Diagnostic Test
- TEST FOR INTERMITTENT CONDITION NOTE:
Check for any TSB(s) related to the condition. If a TSB applies, perform the procedure outlined in the TSB before continuing.
NOTE:Make sure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.
NOTE:Make sure the scan tool is updated to the latest software.
NOTE:If the scan tool displays any error messages involving the Diagnostic CAN C circuits, diagnose and repair the errors before proceeding. Refer to the DTC INDEX article.
NOTE:A loss of communication with the TIPM can cause the ECU View button on the scan tool to be inoperative (not highlighted).
- Turn the ignition on.
- With the scan tool, attempt to select ECU View.
Can the scan tool communicate with the TIPM?
Yes
- The no response condition is not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring for chafed, pierced, pinched, and partially broken wires and the wiring harness connectors for broken, bent, pushed out, and corroded terminals.
No
- Go To Step 2
- DIRECT BATTERY FEED CIRCUIT OPEN AT TIPM
- Disconnect the scan tool from the DLC.
- Using a 12-volt test light connected to ground, check the (A0) B(+) circuit at the TIPM C9 connector.
Does the test light illuminate brightly?
Yes
- Go To Step 3
No
- Repair the open in the (A0) B(+) circuit.
- Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
- GROUND CIRCUITS OPEN AT TIPM
- Turn the ignition off.
- Disconnect the TIPM C1, C2, C6, and C11 harness connectors.
- Using a 12-volt test light connected to 12-volts, check the (Z901) Ground circuits in the TIPM harness connectors.
Does the test light illuminate brightly on each circuit?
Yes
- Go To Step 4
No
- Repair the open in the (Z901) Ground circuit that did not illuminate the test light.
- Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

- Disconnect the TIPM C3 harness connector.
- Measure the resistance on the (D72) Diagnostic CAN C (+) circuit between the TIPM C3 harness connector and the DLC.
Is the resistance above 10.0 Ohms?
Yes
- Repair the (D72) Diagnostic CAN C (+) circuit for an open.
- Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
No
- Go To Step 5
- CHECK FOR (D71) DIAGNOSTIC CAN C (-) CIRCUIT OPEN AT DLC
Courtesy of CHRYSLER GROUP, LLC
- Measure the resistance on the (D71) Diagnostic CAN C (-) circuit between the TIPM C3 harness connector and the DLC.
Is the resistance above 10.0 Ohms?
Yes
- Repair the (D71) Diagnostic CAN C (-) circuit for an open.
- Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
No
- Go To Step 6
- Measure the resistance on the (D71) Diagnostic CAN C (-) circuit between the TIPM C3 harness connector and the DLC.
- CHECK FOR (D72) DIAGNOSTIC CAN C (+) CIRCUIT SHORTED TO GROUND Fig 4: Measuring Resistance Between Ground & Diagnostic Can C (+) Circuit At TIPM C3 Harness Connector

- Measure the resistance between ground and the (D72) Diagnostic CAN C (+) circuit at the TIPM C3 harness connector.
Is the resistance below 100.0 Ohms?
Yes
- Repair the (D72) Diagnostic CAN C (+) circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
No
- Go To Step 7
- Measure the resistance between ground and the (D72) Diagnostic CAN C (+) circuit at the TIPM C3 harness connector.
- CHECK FOR (D71) DIAGNOSTIC CAN C (-) CIRCUIT SHORTED TO GROUND Fig 5: Measuring Resistance Between Ground & Diagnostic Can C (-) Circuit At TIPM C3 Harness Connector

- Measure the resistance between ground and the (D71) Diagnostic CAN C (-) circuit at the TIPM C3 harness connector.
Is the resistance below 100.0 Ohms?
Yes
- Repair the (D71) Diagnostic CAN C (-) circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
No
- Go To Step 8
- Measure the resistance between ground and the (D71) Diagnostic CAN C (-) circuit at the TIPM C3 harness connector.
- CHECK FOR DIAGNOSTIC CAN C CIRCUITS SHORTED TOGETHER Fig 6: Measuring Resistance Between Diagnostic CAN C (+) Circuit & Diagnostic CAN C (-) Circuit At TIPM C3 Harness Connector

- Measure the resistance between the (D72) Diagnostic CAN C (+) circuit and the (D71) Diagnostic CAN C (-) circuit at the TIPM C3 harness connector.
Is the resistance below 100.0 Ohms?
Yes
- Repair the (D72) Diagnostic CAN C (+) circuit for a short to the (D71) Diagnostic CAN C (-) circuit.
- Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
No
- Replace the Totally Integrated Power Module in accordance with the Service Information.
- Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
- Measure the resistance between the (D72) Diagnostic CAN C (+) circuit and the (D71) Diagnostic CAN C (-) circuit at the TIPM C3 harness connector.
