B2102-IGNITION RUN/START INPUT CIRCUIT HIGH

For a complete wiring diagram, refer to the Wiring Information.

When Monitored:
With the ignition switch off.
Set Condition:
The Totally Integrated Power Module (TIPM) receives a CAN Bus message that indicates the ignition status equals OFF/LOCK, while the hardwired Run/Start input indicates the ignition switch is in the RUN/START position.

Possible Causes
(F20) IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT SHORTED TO VOLTAGE
TOTALLY INTEGRATED POWER MODULE (TIPM)

1. CHECK FOR ACTIVE DIAGNOSTIC TROUBLE CODE (DTC)

1.	Turn the ignition off.

2.	Using the scan tool, read active TIPM DTCs.

Does the scan tool display this DTC as active?

Yes

The condition that caused this code to set is not present at this time. 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 the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

2. CHECK THE (F20) IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT FOR A SHORT TO BATTERY VOLTAGE

1.	Turn the ignition off.

2.	Disconnect the TIPM C7 harness connector.

3.	Cycle the ignition on and off.

4.	Using a 12-volt test light connected to ground, check the (F20) Ignition Switch Output (Run-Start) circuit at the TIPM C7 harness connector.

Does the test light illuminate brightly?

Yes

Repair the (F20) Ignition Switch Output (Run-Start) circuit for a short to battery voltage.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

Replace the Totally Integrated Power Module (TIPM) in accordance with the Service Information.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).
