Test Description
The numbers below refer to the step numbers on the diagnostic table.
-
This step tests for voltage at the coil side of the lock cylinder relay.
-
This step verifies that the dash integration module (DIM) is providing ground to the lock cylinder relay.
-
This step tests if ground is constantly being applied to the ignition lock cylinder control actuator.
