Did you perform the Instrument Cluster Diagnostic System Check?

Go to Step 2

Go to Diagnostic System Check - Instrument Cluster

1. Turn the ignition ON, with the engine OFF.
2. Observe the instrument panel cluster (IPC).

Does the IPC perform the displays test?

Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems

Go to Step 3

1. Turn the ignition OFF.
2. Disconnect the IPC.
3. Turn the ignition ON, with the engine OFF.
4. Connect a test lamp between the ignition 1 voltage circuit of the IPC and a good ground.

Does the test lamp illuminate?

Go to Step 4

Go to Step 7

Connect a test lamp between the ignition 1 voltage circuit of the IPC and the ground circuit of the IPC.

Does the test lamp illuminate?
