Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test


2. WIRELESS IGNITION NODE (WIN)

Turn the ignition on.
Using the scan tool, read WIN DTC(s).
Does the scan tool display this DTC as active?

Yes


- Go to 3


No

- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test


3. (F20) IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT SHORTED TO GROUND




Turn the ignition off.
Disconnect the TIPM C7 harness connector.
Turn the ignition on.
Using a 12-volt test light connected to battery, probe the (F20) Ignition Switch Output (Run-Start) circuit in the WIN harness connector.
Does the test light illuminate brightly?

Yes


- Repair the (F20) Ignition Switch Output (Run-Start) circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test


No


- Go To 4


4. CHECK TIPM FUSE
Turn the ignition off.
Check the M27 fuse in the TIPM.
Is the fuse blown?

Yes


- Replace the TIPM.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test


No


- Go To replace the Ignition Switch.
