Circuit/System Testing

1. Ignition OFF, disconnect the X1 harness connector at the DIC.
2. Ignition OFF, test for less than 1 ohm of resistance between the ground circuit terminal listed below and ground.

* Terminal 1
* Terminal 2


• If greater than the specified value, test the appropriate ground circuit for an open/high resistance.

3. Ignition ON, verify that a test lamp illuminates when connected between the B+ circuit terminal listed below and ground.

* Terminal 3
* Terminal 5


• If the test lamp does not illuminate, test the appropriate B+ circuit for an open/high resistance. If the circuit tests normal, test or replace the DIC.




Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
