Retrieving Diagnostic Trouble Codes
- Ensure ABS warning light operates for 2 seconds after ignition switch is turned on (bulb check). If ABS warning light does not operate, go to appropriate test under SYMPTOM TESTS . If ABS warning light is okay, go to next step.
- Connect jumper wire between ground terminal and diagnosis switch terminal on diagnostic connector. See Fig 1 . Turn ignition on. Monitor ABS warning indicator light. DTCs are indicated by "blinking sequence". First and second digits of 2-digit DTC are separated by a one second pause. Lowest number DTC is displayed first.
- If a fault is indicated, go to appropriate DTC circuit test under DIAGNOSTIC TESTS . See ABS DIAGNOSTIC TROUBLE CODE INDEX . Turn ignition off and disconnect jumper wire.
