Retrieving Trouble Codes

Turn ignition on (without engine running). Ensure ABS warning light comes on. Start engine, and observe ABS warning light. If warning light goes out, no trouble codes exist.
If ABS warning light stays on, turn ignition off. Remove access cover on passenger-side of center console to locate 2-pin connector. Install jumper wire between pins on 2-pin connector. See Fig 1 .Turn ignition on (without engine running). Record blinking ABS warning light sequence.

After ignition is turned on, ABS warning light will turn on for one second, then pause for 2 seconds before blinking first code. First code number indicates main code and second code number indicates sub code. See Fig 2 . Three codes can be set at once. To recheck sequence, turn ignition off for a few seconds, and then turn it on again. After trouble codes have been retrieved, conduct appropriate test procedures outlined in flow charts. See ABS SELF-DIAGNOSTIC FLOW CHARTS.
