Continuity Check
- Disconnect instrument cluster connectors. See Figure. Check continuity between terminal 2H on instrument cluster harness connector (left side) and PCM terminal 43. See Fig 1. Continuity should exist. If continuity is not as specified, inspect the wiring harness (instrument cluster to PCM). If continuity is as specified, go to the next step.
- Check continuity between terminals 1J and 2H on instrument cluster connectors. See Figure. Continuity should exist. If continuity is not as specified, replace instrument cluster or bulb.
