Reading and Clearing Diagnostic Trouble Codes

Diagnostic Trouble Code (DTC) Retrieval:

2. Turn the ignition switch ON, but do not start the engine.

Diagnostic Trouble Code (DTC) Blinking Frequency Chart:

3. Record the blinking frequency of the ABS indicator light. The blinking frequency indicates the diagnostic trouble code (DTC).

CAUTION: Before starting the engine, disconnect the jumper wire from the service check connector, or else the Malfunction Indicator Lamp (MIL) will stay ON with the engine running.



NOTE:
- The ABS control unit can only indicate three DTCs at a time (one, two or three problems).
- If the ABS indicator light does not light, refer to ABS Light Testing. ABS Light
- If you miscount the blinking frequency, turn the ignition switch OFF then ON to cycle the ABS indicator light again.
- After the repair is completed, disconnect the ABS B2 (15 A) fuse in the under-hood fuse/relay box for at least three seconds to erase the ABS control unit's memory. Then turn the ignition key ON again and recheck.
- The memory is erased if the connector is disconnected from the ABS control unit or the ABS control unit is removed from the body.
- After recording the DTC (if applicable), refer to the Symptom-to-System Chart.
