Diagnostic Aids
WARNING: This page is about a different car, the 2004 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
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 short in deceleration sensor to EBCM wiring circuits
- An open or high resistance in the ignition positive voltage circuit
- An open or high resistance in the deceleration sensor ground circuit
- A deceleration sensor malfunction
- An internal EBCM malfunction
If an intermittent malfunction exists, refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
