Tech Tip: Subaru Parasitic Battery Draw Eastpointe MI
This bulletin provides the diagnostic procedure when checking for excessive battery draw for any Subaru model. Test procedure includes: Connect one end of the bypass wire to the battery’s negative post, then connect the other end to the negative battery cable end. Simply wrapping then twisting the stripped back ends of the bypass wire around the post and terminal will be sufficient. Reinstall the negative cable on the battery post, and more.
Diagnostic Solutions: Brake Maintenance & Inspection Eastpointe MI
Although brake systems wear at a relatively glacial rate, a point will be reached when they can no longer stop the vehicle in an emergency situation and brake system inspections are therefore required to prevent accidents caused by brake component failure. Inspection procedures vary from area to area. Mountainous or metro-area driving conditions, for example, obviously demand more brake performance than do plains-area conditions.
Tech Feature: Diagnosing Intermittent Driveability Issues Eastpointe MI
Common causes of intermittent stalling may include a bad idle speed control (ISC) system, low fuel pressure, loss of ignition, vacuum or EGR leaks, or other problems we’ll get to later in this article. The engine’s idle speed is controlled by how much air is allowed to bypass the throttle via the idle bypass circuit in the throttle body. The PCM monitors idle speed and operates a solenoid or small electric motor to move a valve that regulates airflow through the air bypass circuit.
Toyota Tech: Diagnosing Today's Complex Electronics Systems Eastpointe MI
The factory scan tool can obviously read and access the full range of onboard diagnostics on any late-model Toyota (back to 1989), including powertrain, body, ABS and other systems. The tool also allows a technician to simultaneously view and analyze onboard vehicle data, browse relevant technical bulletins and even reprogram the vehicle from the driver’s seat via the wireless TIS connection.

Diagnostic Solutions: Upgrades That Deliver Performance and Pizzazz Eastpointe MI
As import car techs, we can't ignore Korean-made cars: They're making the same inroads into the market that the Japanese cars did in the late '70s and early '80s. By providing good value, quality cars and strong warranties, there's no reason to think they won't enjoy the same success.
Analyzing Ignition Misfires and Plotting a Diagnostic Course Eastpointe MI
Random misfires are another type of misfire that can be hard to nail down. Random misfires that jump around from one cylinder to another may also be caused by a lean fuel condition or a weak spark. The challenge here is figuring out what's upsetting the fuel mixture or robbing the spark.
Diagnosing Honda Accord EX with Trouble Code P0325 Eastpointe MI
An illuminated check engine light on a customer's 1998 Honda Accord EX, that is registering a trouble code P0325, could be caused by the knock sensor, the connection, wire harness or the Engine Control Module (ECM).
Diagnosing Mercedes-Benz Low Range Light Flashes, Code P1831 Eastpointe MI
If you receive customer reports in the affected model vehicles of the low range light flashing rapidly (18 times) after vehicle start with fault code P1831 (positioner motor, position sensor or power supply is faulty) in transfer case ECU, do not replace the transfer case motor.
Diagnosing the Blue Car Syndrom of a Random Stalling Condition Eastpointe MI
Blue Car Syndrome is the non-technical term for a very common phenomenon. It is the experience that many people possess regarding having a specific observation, idea, experience, etc., enter one's consciousness, and then having it seem that the same observation or experience begins to occur with increased frequency.
Diagnostic Dilemmas: The Pressures of Intake Manifold Vacuum Tests Eastpointe MI
Several years ago, a retired school teacher brought in a 1994 Chevrolet S-10 Blazer that had developed an intermittent rough idle condition. Although a rebuilt engine had been installed a year before, and all of the wiring and vacuum hoses looked as if they were in factory condition, I took nothing for granted.
Diagnostic Solutions: Brake Maintenance & Inspection Eastpointe MI
Although brake systems wear at a relatively glacial rate, a point will be reached when they can no longer stop the vehicle in an emergency situation and brake system inspections are therefore required to prevent accidents caused by brake component failure. Inspection procedures vary from area to area. Mountainous or metro-area driving conditions, for example, obviously demand more brake performance than do plains-area conditions.
Diagnostic Solutions: Charging System Diagnostics & Troubleshooting Eastpointe MI
Caster is defined as the forward (negative) or rearward (positive) tilt of the steering axis as viewed from the side. Caster is measured in degrees from an imaginary line perpendicular (90 degrees) to the road surface. Zero caster would be a line straight up and down.
Diagnostic Solutions: Charging System Service Eastpointe MI
Drive belts last so long on late-model imports that it's very easy to forget about inspecting them during a scheduled maintenance interval. In the early days of import cars, drive belts didn't last as long because many were made from a leather belt joined together by a mechanical coupler or from cut leather links that looped together to make the belt adjustable.
Diagnostic Solutions: COP Ignition Systems Eastpointe MI
By using various data inputs including engine speed, calculated engine load, throttle opening and coolant temperature, the PCM can calculate the spark advance needed for maximum power and fuel economy, and minimum exhaust emissions under various operating conditions.
Diagnostic Solutions: Cylinder Head Service, Restoring the Engine to Precise OE Tolerances Eastpointe MI
Although cylinder head repairs have been a staple of the import repair shop for many years, modern technology has changed the way we should sell and perform cylinder head services.
Diagnostic Solutions: Fuel System Pressure & Volume Checks Eastpointe MI
Because the fuel injector's job is to mix fuel with the intake air charge, it must produce a finely misted, conical spray pattern through the fuel injector nozzle. Lower-than-specified fuel pressures not only fail to provide enough fuel for combustion at larger throttle openings, but may also introduce an uneven air/fuel charge distribution into the combustion chamber itself, which usually results in hard starting, hesitation and reduced power output.
Diagnostic Solutions: Identifying Ignition Switch Failure Symptoms Eastpointe MI
lthough the basic ignition switch has remained unchanged for many years, the way it supplies electrical current to modern on-board electronics has made it a key factor when diagnosing intermittent failures in various electronic operating systems. Going back into automotive history, the ignition switch's sole purpose on early imports was to energize the primary ignition system circuit as the engine was being cranked.
Diagnostic Solutions: Master Cylinder Diagnosis Eastpointe MI
The most important point to remember during any master cylinder diagnosis is that an inch of travel at the brake pedal translates into only a few thousandths of an inch of piston travel at a disc brake caliper or brake cylinder. Consequently, the fluid displacement of a master cylinder is matched very closely to the fluid volume requirements of the brake system itself.
Diagnostic Solutions: Noise, Vibration & Harshness Diagnosis Eastpointe MI
Unfortunately for those of us in the auto repair business, even our best customers have the occasional need for noise, vibration and harshness (NVH) diagnostics. On the plus side, if NVH diagnostics are approached in a methodical manner, profitability and customer satisfaction can be greatly improved.
Diagnostic Solutions: Oil Filters Eastpointe MI
Most veteran technicians remember when oil filters didn't appear as standard equipment on many automobiles until mid-century. As time progressed, oil filtration became standard equipment because technical innovations such as hydraulic valve lifters or valve lash tensioners required clean, particle-free oil to ensure that check valves inside the lifter or tensioner would function perfectly during each valve-opening event.
Diagnostic Solutions: Oxygen Sensor Diagnostics Eastpointe MI
Before we venture into basic PCM operating strategies and diagnostic procedures, let's review how a simple, single-wire zirconia oxygen sensor works in conjunction with the PCM. A closed-loop fuel control system must contain three essential components: an information processor (the PCM), an actuator (the fuel injector) and an exhaust gas sensor (the oxygen sensor). During a cold startup, the PCM operates briefly in an open-loop or fixed fuel-control mode until the oxygen sensor reaches at least 600° F operating temperature.
Diagnostic Solutions: Profitable Radiator Service Eastpointe MI
The volume of the coolant flow throughout the engine must be sufficient to remove excess heat from the engine block assembly. If the thermostat doesn't completely open, a restriction is created that reduces coolant flow volume to the radiator. In other cases, if the water pump's impellor slips on the shaft or if the impellor has become worn, corroded or broken, coolant flow to the radiator is similarly reduced.
Diagnostic Solutions: Reading Spark Plugs is as Much an Art as It is a Science Eastpointe MI
Originally, the starter motor pinion gear was manually engaged with the flywheel gear by pressing and releasing a spring-loaded pedal. Later versions used an inertia-based drive pinion that spun along a helical spline cut into the motor shaft to engage the flywheel gear. The inertia drive was eventually discarded because it would usually disengage at a critical time when trying to clear a flooded engine.
Diagnostic Solutions: Replacing Water Pumps as Preventive Maintenance Eastpointe MI
Water pumps serve as an idler pulley on many engines equipped with timing belts and, due to accessibility issues on many transverse engines, so they should be replaced during any major timing cover service. Read on to know this preventive maintenance.
Diagnostic Solutions: Steering Gears Eastpointe MI
As vehicles became heavier and more difficult to steer, auto manufacturers developed different types of steering gears designed to change the rotating motion of the steering wheel and shaft into a lateral motion transmitted through the steering linkage to the steering knuckles and front wheels. This system has prevailed to this day.
Diagnostic Solutions: Wheel Bearing Diagnosis Eastpointe MI
Although wheel bearings are often the most neglected part of the vehicle, they nevertheless have a critical job to do, and in most cases, do it very well. Not only are wheel bearings designed to support the weight of the vehicle and allow it to travel over a road with a minimum of rolling friction, the bearings must also withstand the thrust loads generated by high-speed cornering and hard acceleration and braking.
Diagnostics Through CAN Networks Eastpointe MI
Since model year 2003, a growing number of domestic and import vehicles have been built with a new onboard communications protocol called CAN (Controller Area Network). CAN is essentially an engineering standard for how computers and modules talk to one another via the serial data bus in a vehicle's wiring system. It's a high speed standard designed for powertrain control modules, anti-lock brakes and stability control systems.
Dodge Brake Repair Eastpointe MI

Mazda Driveability Diagnostics and Check Engine Light Complaints Eastpointe MI
The most common failure we see on Mazda models is a torn air intake hose between the airflow sensor and the throttle body. The symptoms that result from this failure are hard to miss. The usual complaint is a big stumble or stall on initial acceleration.
Mercedes 'CAN' Diagnostics - Uncovering Faults Speeds The Repair Process Eastpointe MI
On Mercedes cars, CAN wiring has been incorporated since 1992 to allow the sharing of information that is used for the engine, transmission, airbag, anti-lock brakes and suspension control systems. Mercedes uses a two-wire system, which allows two data streams.
Mode $06 Diagnostic Update Eastpointe MI
Mode $06 has been around since the introduction of second-generation onboard diagnostic (OBD II) systems back in the mid-1990s. Essentially, Mode $06 is the raw test data the OBD II system uses to evaluate the operating status of various components in the engine management and emission control systems.
OBD II Diagnostics:Tips and Tricks to Make the Process Easier Eastpointe MI
The Malfunction Indicator Lamp (MIL) can be a golden light of opportunity for your shop. If the light comes on, it means the Onboard Diagnostics II system (OBD II) has detected an emissions-related problem. OBD II is designed to turn on the MIL if a problem occurs that may cause emissions to exceed federal limits by 150 percent. The problem has to occur more than once, and it must be significant enough to create a potential emissions problem (one serious enough to prevent a vehicle from passing an emissions test).
Starting/Charging System Diagnosis: Fixing Faults the First Time Eliminates Comebacks & Returns Eastpointe MI
How many starters and alternators are replaced unnecessarily every year because of misdiagnosis? Nobody knows for sure, but suppliers of both new and remanufactured rotating electrical parts tell us more than half of their warranty returns have "no fault found" when the parts are examined.
Subaru Tech Tip: Diagnosing Idle Surges on Legacy Models Eastpointe MI
If you encounter a driveability concern such as idle surges or whistling, it may be caused by carbon buildup on the Idle Speed Control (ISC) valve. In these cases, it is not necessary to replace the ISC valve. Cleaning the ISC valve could correct the condition. To clean an ISC valve, perform the repair procedure.
Tech Feature: Diagnosing Intermittent Driveability Issues Eastpointe MI
Common causes of intermittent stalling may include a bad idle speed control (ISC) system, low fuel pressure, loss of ignition, vacuum or EGR leaks, or other problems we’ll get to later in this article. The engine’s idle speed is controlled by how much air is allowed to bypass the throttle via the idle bypass circuit in the throttle body. The PCM monitors idle speed and operates a solenoid or small electric motor to move a valve that regulates airflow through the air bypass circuit.
Tech Tip: Diagnosing an Engine that Won't Start Eastpointe MI
If the fuel pump doesn’t buzz and generate pressure when the ignition key is turned on, it doesn’t necessarily mean the fuel pump has failed. The problem could be a bad fuel pump relay, a blown fuel pump fuse, a loose or corroded wiring connector anywhere in the fuel pump electrical circuit, or even a fault in the PCM itself.
Tech Tip: Subaru Parasitic Battery Draw Eastpointe MI
This bulletin provides the diagnostic procedure when checking for excessive battery draw for any Subaru model. Test procedure includes: Connect one end of the bypass wire to the battery’s negative post, then connect the other end to the negative battery cable end. Simply wrapping then twisting the stripped back ends of the bypass wire around the post and terminal will be sufficient. Reinstall the negative cable on the battery post, and more.

Tech Update: A to VSV...Troubleshooting Toyota/Lexus EVAP Systems Eastpointe MI
The first step is to seal the system for testing. This is usually accomplished by sealing the air vent line to the tank and any other normally open vent lines in the system. One trick I've learned is to first hook up to the PCM and enter via Global OBD II.
The Ins and Outs of Diagnosing Battery, Charging and Starter Problems Eastpointe MI
If the battery is low or getting old, the starter is weak or there's too much resistance in the starting circuit, the combination of increased cranking load and reduced battery capacity may prove to be too much when temperatures drop. The engine may not crank fast enough to start, or it may not crank at all.
Toyota Tech: Diagnosing Today's Complex Electronics Systems Eastpointe MI
The factory scan tool can obviously read and access the full range of onboard diagnostics on any late-model Toyota (back to 1989), including powertrain, body, ABS and other systems. The tool also allows a technician to simultaneously view and analyze onboard vehicle data, browse relevant technical bulletins and even reprogram the vehicle from the driver’s seat via the wireless TIS connection.
Troubleshooting MIL Issues: OBD II & "CAN" Scan Tool Diagnostics Eastpointe MI
The MIL light is an emissions warning light. It's not an engine maintenance reminder light, an overheating warning light, a low oil pressure warning light or a low charging voltage light. If the MIL is on, it means the onboard diagnostic system (OBD II) has detected a fault that may cause emissions to rise and has set a Diagnostic Trouble Code (DTC) that corresponds to the problem.
