Diagnostic Aids
WARNING: This page is about a different car, the 2003 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
Check for any of the following conditions:
- The resistance of the circuit opening relay, the resistance across terminals No. 2 and 3 is 85-95 ohms at 68°F (20°C). The resistance across terminals No. 1 and 4 is infinite.
- The circuit opening relays electrical contacts may be pitted or sticking. Replace the relay if tapping gently on the relay or wiggling the relay causes a change in the relays operation.
- The performance of the circuit opening relay may be affected by temperature. Check the relay after sitting outside overnight and after running the engine 30 minutes.
