Diagnostic Aids
Thoroughly inspect the wiring and the connectors. An incomplete inspection of the wiring and the connectors may result in a misdiagnosis, causing a part replacement with the reappearance of the malfunction.
The following are possible causes of the malfunction:
- An open or high resistance in the ABS indicator control circuit
- An open, high resistance or short to ground in the IPC ignition voltage circuit
- An open or high resistance in the EBCM ground circuits
- An internal EBCM malfunction
- An internal IPC malfunction
If an intermittent malfunction exists, refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
