Question about 2006 Chevrolet TrailBlazer LT

Parking Brake, ABS, Traction Control & Anti Skid lights on

When I start the vehicle, none of the lights come on. Within the first 1/4 mile of driving, you can feel the ABS acting up with a pulsating feel in the brake pedal. Then I get exactly 33 tones and the parking brake, abs, traction control and anti skid lights all come on. The brakes work fine after that. The system resets itself everytime you turn off the engine. Any idea what can be causing this problem?

One or more of the sensors in the wheels that are responsible for these functions is faulty. It is sending a signal that is mucking up the calculations that control the brakes and engine for traction control and anti skid. All of them need to be checked!

    Are you talking about the tone ring inside the axle?

    No, the sensors on the wheels and brakes.

SOURCE: ABS light and Traction control light stay on.

That "grindy" feeling is when the ABS kicks in. It's only suppose to activate when you slam on the brakes and the wheels would normally lock. Instead, ABS will very quickly pump the brakes on and off, to prevent the wheels from locking (making a giant skid mark) and stopping the car more effectively. Generally this only happens if you slam on the brakes or loose traction due to rain or snow while braking. If this is happening often and the brake light is on, on the dash, then you need to get this checked out by a qualified mechanic ASAP.

Abslight stays on. How to fix? This is a2007trailblazer?


First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

Why does my ABS light stays on and sometimes i get a vibration in the brake petal causing my 2002 Cadillac escalade not wanting to stop?


Sounds like a fault with the Antilock Braking System. The vibration in the pedal is the ABS working. With your foot on the brake pedal, it releases and re-applies the brakes to stop a skid from the wheels locking up. You need professional service for brakes.

Seems to be a known issue on all Cadillac and requires the ABS module to be replaced.

PRE-DIAGNOSTIC INSPECTIONBefore diagnosing ABS/TCS, perform a comprehensive visual inspection of system as follows.Check ABS/TCS wiring harness connectors for looseness. Check harness routing; pay particular attention to wheel speed sensor wiring harness routing. Check fuses No. 1D, 5B and 6B in instrument panel fuse block. Check fuses No. 1 and 2 in underhood fuse block. Check brake fluid level in master cylinder reservoir. Check brake fluid level in Pressure Modulator Valve (PMV) assembly reservoir. Ensure parking brake is fully released. Ensure parking brake switch is functioning properly. Always perform ABS/TCS system functional check before using DIAGNOSTIC CODE CHARTSThe EBCM/EBTCM has self-diagnostic capability, which can detect system failures. Fault codes stored by EBCM/EBTCM can be displayed using Tech 1 scan tester. There are no provisions for flash code diagnostics.Begin ABS/TCS diagnosis with PRE-DIAGNOSTIC INSPECTION procedure. If failures are found during pre-diagnostic inspection, perform necessary repairs, and proceed with ABS/TCS FUNCTIONAL CHECK. See Fig. 5 .If no failures are found during pre-diagnostic inspection, go to ABS/TCS FUNCTIONAL CHECK. See Fig. 5 . The ABS/TCS FUNCTIONAL CHECK will either indicate ABS/TCS is functioning properly or direct technician to various diagnostic procedures such as diagnostic charts, symptom diagnosis or BRAKE warning light diagnosis.CHART D - TRACTION OFF WARNING LIGHT ON CONTINUOUSLY & NO DTC SET (BUICK WITH UH8 OR U2A INSTRUMENT CLUSTER)Circuit DescriptionWhen ignition switch is first turned to RUN position, EBTCM goes through a self-test, which lasts 2-4 seconds. During self-test, EBTCM commands TRACTION OFF indicator warning light on. Powertrain Control Module (PCM) can also command EBTCM to set a Code 75 which will illuminate TRACTION OFF indicator.Traction control switch is located either on instrument panel center trim plate or driver's front door trim panel. Switch allows driver to select traction control mode (on/off). When traction control system is turned off, TRACTION OFF warning light comes on.EBTCM monitors transaxle temperature through

I have a 2002 VW New Beetle. The ABS light has come on and there is a chiming beep and the ABS light flickers. What could be the problem?


ABS - Anti-lock Brake System.
If the ABS lights on the dashboard permanently the ABS system is faulty. You must access the ABS Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ABS ECU, in other words reset the ABS system and turn off the warning lamp on dashboard.
ASR - Acceleration Skid Control system.
When ASR warning light blinking the system is activated itself for car acceleration skid control.

For today's typical high-torque engines, traction control (ASR) can increase both comfort and safety, particularly when driving on slippery roads or surfaces offering differing levels of grip. Traction control permits smooth starting and acceleration through the full speed range without wheel-spin or fishtailing.
tdisline_703.jpg


ASR only operates in conjunction with the electronic accelerator (E-gas) and uses components of the anti-lock braking system (ABS). If one wheel suddenly begins to rotate faster than the others (slip), ASR intervenes in the engine management system and reduces power until the wheel stops spinning.
The ASR system represents a further contribution to active safety as it maintains vehicle traction and directional stability throughout the acceleration phase at any speed. In addition, it reduces tyre wear. Activation of the ASR system is indicated by a flashing indicator lamp in the instrument cluster.
The ESP system means the Electronic Stability Program. ESP system includes the ABS system.

2001 Mercury Grand Marquis brake and ABS dash lights on and off


The red brake light is the key here. That usually indicateds a hydraulic problem. Check you fluid level in master cylinder and see if it is low. Also the level indicator sensor there in the master cylinder maybe sticking or corrioded. If ABS sees the red brake light it will shut off and turn on the ABS light,also traction control would be disabled as well.
