Gauge Test

WARNING: This page is about a different car, the 2005 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

Using a scan tool, the instrument cluster can check all the gauges. While in this mode, the EMIC will sweep the gauge pointer from low to high, stopping at predetermined points. Each gauge must be checked individually by selecting the specific gauge from the scan tool menu.

Successful completion of the cluster tests will confirm that the instrument cluster is operational. However, there may still be a problem with the CAN data bus, the Powertrain Control Module (PCM), the Front Control Module (FCM), the Transmission Control Module (TCM), the Occupant Restraint Controller (ORC), the Controller Anti-lock Brake (CAB), or the hard wired inputs to one of these electronic control modules. Use a diagnostic scan tool to diagnose these components. Refer to INSTRUMENT CLUSTER - ELECTRICAL DIAGNOSTICS .
