Good morning,

Does the car run?

The ABS system has a fault code stored. When this happens, it will take the trac system off line until the ABS is repaired.

As far as the headlights, did anyone verify power to the headlights to be sure the bulbs are good?

Can you post the other codes?

Okay,

That is a lot of codes. Chances of all that going wrong at the same time is very small.

I would start by load testing the battery. Low voltage is a common reason for a lot of codes.

Check your charging system for 14 to 14.5 volts. Also, check for any Ac voltage while the engine is running. That will confuse the ECM and it will throw a lot of codes.

Okay. As I stated before, the ABS will take the trac system out of service until it is repaired.

As far as the brake light, that should be the red brake light related to the ABS.

Can you check the codes now?

What about the charging system as I stated before? Voltage both AC and DC?

You need a volt meter to do those checks. If you do not have one, you can get one at a parts store for cheap.

Let me check the code.

Okay, check the brake light switch on the brake pedal. That is what controls the interlock for shifting. Once again, you need a voltmeter to test for voltage on both sides when the pedal is depressed.

As far as the code, it is for the wheel speed sensor. They need to be checked or monitored to see if they are sending signals.

You need an advanced scan tool to monitor these sensors.

I am trying to find a wiring diagram for the ABS system so you can verify powers and grounds to the unit but I am not having much luck finding one.

I will keep looking for you.

Clearing does nothing until the issue is determined and repaired.

I found this diagram. Take a look at it.

You would need to download and then you can enlarge it.
