TEST

ACTION

APPLICABILITY

3

Turn the ignition off.
Disconnect the BCM C2 harness connector.
Disconnect the Ignition Switch harness connector.
Measure the resistance of the Ignition Switch Output (Run-Start) circuit between the
BCM C2 connector and the Ignition Switch connector.
Is the resistance above 5.0 ohms?

All

Yes

→ Repair the Fused Ignition Switch Output (Run-Start) circuit for

an open. If the fuse is open make sure to check for a short to
ground.
Perform BODY VERIFICATION TEST - VER 1.

No

→ Replace and program the Body Control Module in accordance

with the Service Information.
Perform BODY VERIFICATION TEST - VER 1.
