| (D72) DIAGNOSTIC CAN C (+) CIRCUIT SHORTED TO GROUND |
| TOTALLY INTEGRATED POWER MODULE |
1. CHECK THE STATUS OF THE ERROR MESSAGE
| NOTE: | Ensure the vehicle being tested is a CAN BUS VEHICLE. If not, false error messages may be displayed. |
| NOTE: | Ensure the scan tool is updated to the latest software. |
| 1. | With the scan tool, record the error message. |
| 2. | Disconnect the scan tool from the DLC. |
| 3. | Cycle the ignition from on to off 3 times. |
| 4. | Turn the ignition on. |
Does the scan tool display this same error message?
Yes
- Go To 2
No
- The conditions that caused this error message to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
2. (D72) DIAGNOSTIC CAN C (+) CIRCUIT SHORTED TO GROUND
| 1. | Turn the ignition off. |
| 2. | Disconnect the TIPM C7 harness connector. |
| 3. | Disconnect the scan tool from the DLC. |
| 4. | Measure the resistance between ground and the (D72) Diagnostic CAN C (+) circuit. |
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 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).
