B2112-5-VOLT SUPPLY CIRCUIT LOW





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

- When Monitored:
With the ignition on.

- Set Condition:
The Totally Integrated Power Module (TIPM) detects a short to ground on the 5-Volt Supply circuit.





1. CHECK FOR ACTIVE DIAGNOSTIC TROUBLE CODE (DTC)
1. Turn the ignition on.
2. 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. A/C PRESSURE TRANSDUCER




1. Turn the ignition off.
2. Disconnect the A/C Pressure Transducer harness connector.
3. Turn the ignition on.
4. Wait 30 seconds
5. Using the scan tool, read DTCs.

Does the scan tool display this DTC as active?

Yes

- Go To 3

No

- Replace the A/C Pressure Transducer.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

3. SHIFT MOTOR/MODE SELECTOR ASSEMBLY




1. Turn the ignition off.
2. Disconnect the Shift Motor/Mode Selector Assembly harness connector.
3. Turn the ignition on.
4. Using the scan tool, read DTCs.

Does the scan tool display this DTC as active?

Yes

- Go To 4

No

- Replace the Shift Motor/Mode Selector Assembly.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

4. (T103) 5-VOLT SUPPLY SHORTED TO GROUND




1. Turn the ignition off.
2. Disconnect the TIPM C4 harness connector.
3. Measure the resistance between ground and the (T103) 5-Volt Supply circuit.

Is the resistance below 10K Ohms?

Yes

- Repair the (T103) 5-Volt Supply circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 5

5. (C818) A/C PRESSURE 5-VOLT SUPPLY SHORTED TO GROUND




1. Disconnect the TIPM C7 harness connector.
2. Measure the resistance between ground and the (C818) A/C Pressure 5-Volt Supply circuit.

Is the resistance below 10K Ohms?

Yes

- Repair the (C818) A/C Pressure 5-Volt Supply circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Replace the Totally Integrated Power Module (TIPM).
- Perform the BODY VERIFICATION TEST. Body Verification Test.
