Go to Step 2

Go to Diagnostic System Check - Instrument Cluster

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

•	Display Mode Switch

•	Display Trip Reset Sw.

•	English/Metric Sw.

•	Info. Reset Switch

•	Information Down Switch

•	Information Up Switch

•	On/Off Switch

•	Trip Odometer A/B Switch

Does the scan tool display On when all switches are pressed and Off when all switches are released?

Does the scan tool display On?

--

Go to Step 14

Go to Step 12

1. Turn ON the park lamps.
2. Cover the ambient light sensor.
3. Observe the operation of all switches on one DIC switch.

Go to Step 11

Go to Step 6

Does the scan tool always display On for the suspect switch?

--

Go to Step 7

Go to Step 8

1. Turn OFF the ignition.
2. Disconnect the DIC switch.
3. Turn ON the ignition, with the engine OFF.
4. With a scan tool, observe the suspect DIC switch parameter.

Does the scan tool display On?

--

Go to Step 9

Go to Step 13

1. Turn OFF the ignition.
2. Disconnect the DIC switch.
3. Connect a 3 amp fused jumper wire between the signal circuit of the suspect DIC switch and a good ground.
4. Turn ON the ignition, with the engine OFF.
5. With a scan tool, observe the suspect DIC switch parameter.

Does the scan tool display On?
