Go to Step 2

Go to Diagnostic System Check - Instrument Cluster

1. Install a scan tool.
2. Turn ON the ignition, with the engine OFF.
3. Press each driver information center (DIC) switch one at a time.
4. With a scan tool, observe the following DIC switch parameters in the instrument cluster (IPC) data list:

•	English/Metric Sw. (base/uplevel)

•	Trip Reset Switch (base)

•	Trip A/B (uplevel)

•	Reset Switch (uplevel)

•	Display Gauge Switch (uplevel)

•	Display Fuel Switch (uplevel)
