    Yes, both lights comes on.

  • topcopbarnes Sep 13, 2010

    Thank you. I am sure I will have to take it to the dealer. At least I have a working understanding of what my vehicle is suffering from. What is scary, the cost! Again, I appreciate your service.

    Thanks for your response!!

    This might be a problem that should be diagnosed by the dealer
    .
    But usually when the ABS and traction lights are both on, it indicates an issue with the EBCM *Electronic brake control module, or a wheel speed sensor. To verify a compatible scan tool is required to communicate with the module. If communication is possible scan for any codes.
    If there isn't a scan tool available check the powers and ground at the EBCM.
    Some mechanic shops might not have the proper tools to diagnose this problem therefore they don't want to get into it.
    You can test the resistance of the front speed sensors. Compare with each other. If they are the same the speed sensors are probably OK. IF sensor replacment is needed, you must replace the whole hub.

    However, there is a technical bulletin which was given for this year and model. Read :-

    Condition

    Some customers may comment on an intermittent or constant ABS malfunction indicator light.
    Cause

    The front wheel speed sensor harness may wear or come into contact with the tie rod end stud. Additionally, the harness may, in some instances, loop over the tie rod stud. In this case, the wheel speed sensor should be examined for damage.
    Correction

    Replace original wheel speed sensor harnesses by splicing in revised wheel speed sensor harnesses. The new design harnesses are of a different length and have revised retention clip locations. Use the following procedure to replace the harnesses.

    1. Raise and suitably support the vehicle on a hoist.
    2. Disconnect the left wheel speed sensor harness from the sensor/bearing assembly.
    3. Remove the harness retainers from the lower control arm.
    4. Follow the harness back to the point where the harness enters the larger engine harness conduit.
    5. Cut the electrical tape and open the conduit. Select a location where the splice will be within the engine harness conduit. Cut the original harness off.
    6. Using GM/Packard Seal and Crimp Connectors, splice the two wires from the new harness to the old. Specific instructions for use of the Seal and Crimp Connectors are printed on the inside of the cardboard overleaf sealing the bag in which the harness is shipped. If Seal and Crimp Connectors are not available, you may use the crimp and solder type included with the harness kit.
    7. Retape the conduit closed making sure to create an effective seal against road splash.
    8. Route the replacement harness following the same path as the original. Fully seat the 4 retainers into the control arm.

    Notice: In the next step you will be required to measure the distance between the last retaining clip in the control arm and the end of the electrical plug that connects to the wheel speed sensor. Failure to properly perform this measurement and suitably adjust the harness may result in entanglement or infringement on the tie rod stud.
    9. Hold the end of the new electrical harness and stretch it firmly. Due to manufacturing tolerances, you will need to measure from the end of the plug (that attaches to the wheel speed sensor) to the rear edge of the first retaining clip. This distance must not exceed 24.7 cm (9.75 in). If the distance is equal to or greater than 24.7 cm (9.75 in), you must move the retaining clip to allow more slack at the control arm and less between the wheel speed sensor and the retainer. Repeat the measurement until properly adjusted.
    10. Disconnect the right wheel speed sensor harness from the sensor/bearing assembly.
    11. Remove the harness retainers from the lower control arm.
    12. Follow the harness back to the point where the harness enters the larger conduit.
    13. Cut the electrical tape and open the conduit. Select a location where the splice will be within the larger harness conduit. Cut the original harness off.
    14. Using GM/Packard Seal and Crimp Connectors, splice the two wires from the new harness to the old. Specific instructions for use of the Seal and Crimp Connectors are printed on the inside of the cardboard overleaf sealing the bag in which the harness is shipped. If Seal and Crimp Connectors are not available, you may use the crimp and solder type included with the harness kit.
    15. Retape the conduit closed making sure to create an effective seal against road splash.
    16. Route the replacement harness following the same path as the original. Fully seat the 4 retainers into the control arm.

    Notice: In the next step you will be required to measure the distance between the last retaining clip in the control arm and the end of the electrical plug that connects to the wheel speed sensor. Failure to properly perform this measurement and suitably adjust the harness may result in entanglement or infringement on the tie rod stud.
    17. Hold the end of the new electrical harness and stretch it firmly. Due to manufacturing tolerances, you will need to measure from the end of the plug (that attaches to the wheel speed sensor) to the rear edge of the first retaining clip. This distance must not exceed 24.7 cm (9.75 in). If the distance is equal to or greater than 24.7 cm (9.75 in), you must move the retaining clip to allow more slack at the control arm and less between the wheel speed sensor and the retainer. Repeat the measurement until properly adjusted.

I keep getting a message service stabilitrak


StabiliTrak Indicator Light: If the warning light does not come on then, have it fixed so it will be ready to warn you if there is a problem. If it stays on, or comes on when you are driving, there may be a problem with your StabiliTrak system and your vehicle may need service. When this warning light is on, the system is off and will not limit wheel spin. Adjust your driving accordingly.

This light will also flash when the StabiliTrak system is active. If the StabiliTrak system warning light comes on and stays on for an extended period of time when the system is turned on, your vehicle needs service.

The traction control part of StabiliTrak can be turned off by pressing and releasing the StabiliTrak button if both systems (traction control and StabiliTrak) were previously on. To disable both traction control and StabiliTrak, press and hold the button for five seconds.

Traction control and StabiliTrak can be turned on by pressing and releasing the StabiliTrak button if not automatically shut off for any other reason.

When the TCS or StabiliTrak system is turned off, the StabiliTrak light and the appropriate TCS off or StabiliTrak off message will be displayed on the DIC to warn the driver. Your vehicle will still have brake-traction control when traction control is off, but will not be able to use the engine speed management system.

If the StabiliTrak and/or Traction Control are not operating properly, I encourage you to take your vehicle in for inspection. A certified technician will be able to offer a more accurate diagnosis.

What causes the "Reduced Engine Power", "Service Stability Control" and "Traction Control" warning lights to come on?


the "Reduced Engine Power", problem causes the PCM to disable "Service Stability Control" and "Traction Control" turning on the warning lights to come on for those systems . The reduced engine power is because of a problem with the electronic throttle control system or as GM calls it TAC system . Reduced Engine Power Mode
When the PCM detects a condition with the TAC system, the PCM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
• Acceleration limiting--The PCM will continue to use the accelerator pedal for throttle control, however, the vehicle acceleration is limited.
• Limited throttle mode--The PCM will continue to use the accelerator pedal for throttle control, however, the maximum throttle opening is limited.
• Throttle default mode--The PCM will turn OFF the throttle actuator motor and the throttle will return to the spring loaded default position.
• Forced idle mode--The PCM will perform the following actions:
- Limit engine speed to idle by positioning the TP, or by controlling the fuel and spark if the throttle is turned OFF.
- Ignore the accelerator pedal input.
• Engine shutdown mode--The PCM will disable fuel and de-energize the throttle actuator.

I have a 2004 2 door Dodge Stratus Coupe, the SRS light is on. The mechanic says it is traction control but I don't know how to turn it off.


I do not know why the mechanic would suggest the SRS warning light relates to the traction control because it has absolutely nothing to do with the TC system.

SRS means "Supplementary Restraint System" - ie, the vehicles airbag system. If the warning light comes on the system has recognised that there is a fault with the airbag system which could mean it would not deploy as designed in the case of an accident. The causes of the warning light can be numerous including a failed sensor, a problem in the wiring or physical interference with the wiring, one of the electrical plug connections coming loose or being disconnected, a problem with the seat belt pretensioners etc etc.

You should take the vehicle to a dealer to have the problem properly diagnosed, rectified and the computer reset.

Normally the warning light will continue to display every time you start driving the vehicle until the cause of the problem is identified and the issue is fixed.

The airbag system is an important safety feature designed to eliminate or reduce injury in the case of an accident. Manufacturers do not include warning systems like this to annoy owners. Just ignoring the warning and looking for ways to just remove the warning would be irresponsible, especially if you are using the vehicle to also carry passengers.

Why does my traction off light come on?


You either have a problem with your engine control system, the traction control system, or you are not in the correct gear. See the explaination below. This is from the 2000 Chevrolet Cavalier Owner's Manual.

TRAC-OFF LIGHT

... If you turn the system off by moving the shift lever

to FIRST (1) or SECOND (2), the warning light will

come on and stay on. To turn the system back on,

move the shift lever back to a position other than

FIRST (1) or SECOND (2). The warning light

should go off. (See "Enhanced Traction System"

in the Index for more information.)

 The warning light will come on when you set your

parking brake with the engine running, and it will

stay on if your parking brake doesn't release fully.

If the transaxle shift lever is in any position other

than FIRST (1) or SECOND (2) and the warning

light stays on after your parking brake is fully

released, it means there's a problem with the system.

 If the traction control system is affected by an

engine-related problem, the system will turn off

and the warning light will come on.

If the Enhanced Traction System warning light comes

on and stays on for an extended period of time when the

transaxle shift lever is in any position other than FIRST
(1) or SECOND (2) your vehicle needs service.

WILL IT HARM THE ENGINE OR VEHICLE IN GENERAL ON A 2001 TAHOE IF YOU CONTINUE TO DRIVE IT WITH THE ABS LIGHT AND TRACTION OFF LIGHT ON?


No you will not "harm" the vehicle.

1. The ABS fault light will mean that the anti - lock braking facility is not working. However the conventional braking system will continue to operate. Bear in mind that you now have no system that prevents you from locking up your brakes so it is all down to the driver.

2. Traction control (TC) warning. The TC function will not be working or not working as programmed. There should be a TC on/off switch or button in the vehicle. Make sure you manually disable the TC by switching the TC OFF until the problem is identified and rectified.
TC is a useful driver aid, especially in slippery road surface conditions, so take extra precautions when driving without it.

Even in good conditions the Tahoe is not a vehicle that handles well.

3. You should get the vehicle checked for the ABS and TC problem. It may only be some faulty sensors that require replacing but a proper diagnosis needs to be made.

T/C light = Traction Control

Could be something going on with a wheel speed sensor. You'll have to have the ABS/TCS controller scanned for any stored trouble codes to see why the controller is turning on the light. The code(s) might help you to determine what part of the system is faulting. You'll have to take it to a shop that has a high end scan tool.

If the TC light is on, chances are there is a trouble code set and stored in the computer. You need to determine what the code is. If you take the car to a nationally recognized parts store, most will scan the computer for free, so there is no money out of pocket for you.


Actron also makes a ABS code checker called BrakeScan. Don't know how good it is, but it might be good for a DIY person.

TC Explanation:

If your vehicle is equipped with the Enhanced Traction System (ETS), this warning light should come on briefly as you start the engine. If the warning light does not come on, then have it fixed so it will be ready to warn you if there is a problem.
If the warning light stays on, or comes on when you are driving, there may be a problem with your Enhanced Traction System and your vehicle may need service. When this warning light is on, the system will not limit wheel spin. Adjust your driving accordingly.
The Enhanced Traction System warning light may come on for the following reasons:
If you turn the system off by moving the shift lever to FIRST (1), the warning light will come on and stay on. To turn the system back on, move the shift lever back to a position other than FIRST (1). The warning light should go off. The warning light will come on when you set your parking brake with the engine running, and it will stay on if your parking brake does not release fully. If the transaxle shift lever is in any position other than FIRST (1) and the warning light stays on after your parking brake is fully released, it means there is a problem with the system. If the traction control system is affected by an engine-related problem, the system will turn off and the warning light will come on. If the Enhanced Traction System warning light comes on and stays on for an extended period of time when the transaxle shift lever is in any position other than FIRST (1), your vehicle needs service.
