B212F-IGNITION RUN/ACC CONTROL CIRCUIT LOW







- When Monitored:
With the ignition on.

- Set Condition:
The Totally Integrated Power Module (TIPM) detects a short to ground condition on the Fused Ignition Switch Output (RUN/ACC) circuit.





1. CHECK FOR ACTIVE DIAGNOSTIC TROUBLE CODE (DTC)
1. Check all fuses.
2. Using the scan tool, read the DTCs.
3. Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 10 seconds.
4. Using the scan tool, read the DTCs.

Does the scan tool display this DTC as active?

Yes

- Go To 2

No

- If the DTC is stored, check for an intermittent condition. Using the wiring diagram/schematic as a guide, visually inspect the related wiring harness connectors. Look for broken, bent, pushed out or corroded terminals.
- Perform the BODY VERIFICATION TEST. Body Verification Test.,

2. CHECK TIPM FOR AN INTERNAL SHORT TO GROUND
1. Turn the ignition off.
2. Remove fuse 16.
3. Turn the ignition on.
4. Using the scan tool, read the DTCs.
