HOW TO - Pull ABS Codes

  • Here's a quick how to pull ABS codes, as I just about found this on probetalk and searched a LONG time to find it! Do this if your ABS (car skidding) light wont go away.

    1. Connect a jumper wire in the diagnostics box from TBS(Test Brake System) to GND terminals.
    2. Connect LED+ to FBS (Fault:Braking System) terminal and LED- to a GND, there are 2 GNDs on the diagnostics box, or any ground will do.
    3. Turn key to ON

    You are meant to use an analog voltmeter, but I found it lit an LED sufficiently.
    Long flashes = tens
    Short flashes = ones
