Question about 2003 Chevrolet Impala

4 Answers

I have a 2003 Chevy impala. The warning lights on gauge are randomly/consistently on for no apparent reason. First the ABS, Brake, and Service Traction Control turned on. Then Air Bag turns on with them. While these are on, turn signals not working, only makes a weird buzzing sound. But still could start and drive car. Now the security light is on with everything else.........no start. Help me.

These are common problems in these models due to defects in Body Control Module and the left inside cabin driver side fuse box.
Test procedure:-
1. In the left hand inside fuse box check voltage on the TURN SIGNAL, SRS, STOP, and ABS/PCM fuse with the key on.

2. If low or no voltage, go to the ignition switch and check the Pink wire for the same condition.

3. Check the two main power feeds into the ignition switch are maintaining voltage.

4. If there is good voltage from ignition switch to the above mentioned fuses, then the problem is with the instrument panel fuse block. Check MIL codes and let me know please to help you further.

Given the wide variety of systems involved it's likely a grounding issue or a main fuse or relay failing.

The only thing I can think of that would explain your problem is a faulty ignition switch.

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

Gauge lights


ABS and Brake warning lights intermittent may be caused by a failing wheel speed sensor(ABS Sensor) and /or its connector. You may have one on each wheel hub(4WD) or if 2WD, a sensor may be on the rear axle differential center.

2005 Chevy impala brake pedal pulsation with brand new rotors installed


Is your ABS working properly? Under heavy braking the ABS should engage and 'pulse' the brakes on/off. It is normal to feel the brake petal flutter or pulse under your foot.

Under light braking there should be no pulsing as the ABS does not engage and you have changed the rotors and pads.

WHEN YOU PRESS THE BRAKE PEDAL DOES THE PEDAL SEEM TO JUMP? IF SO THE MODULE HAS SEEN A WHEEL SPEED SENSOR MPH DROP SIGNALING A BRAKE LOCK UP . OR LOSS OF WHEEL SPEED , IF THATS THE CASE THE MOST COMMON PROBLEM IS A BROKEN WIRE IN THE VEHICLE HARNESS NEAR THE WHEEL SPEED SENSOR CONNECTOR USUALLY WHERE THE HARNESS MAKES A U TURN UPWARDS .

IS THE ABS LIGHT ON ALL THE TIME ORDOES IT RESET WITH A KEY CYCLE?

FIRST OF ALL THE TRACTION CONTROLL AND THE ABS SYSTEM ARE BASICALLY THE SAME SYSTEM.

THERE SHOULD BE SERVICE CODES FOR THE MALFUNCTIONS , FIRST THING IS TO RETRIEVE ALL ABS CODES THEN MONITOR WHEEL SPEED SENSOR INPUTS WHILE DRIVING

HOPE THIS HELPS

2003 Chevy Impala Service Traction Sytem show on Dash


I can't answer the question about the gas fumes, but I had the same problem last year with the "Service Traction Sysytem" message and the Trac and ABS lights coming on in my Impala. Mine turned out to be because of a bad wheel bearing, that was causing the ABS and traction system not to work. I'm not sure if you've experienced this, but another thing that would happen with mine was that I would go to brake and have a hard time depressing the brake pedal, almost like it was pushing back. That is the point when the Trac and ABS lights came on.
