Go to Step 2

Go to Diagnostic System Check - Instrument Cluster

1. Turn the ignition OFF.
2. Disconnect the ambient air temperature sensor.
3. Connect a 3-ampere fused jumper wire between the signal circuit and the ground circuit of the ambient air temperature sensor.
4. Turn the ignition ON, with the engine OFF.

Does the DIC display SC?
