Owners of affected 2021-2024 Jeep Compass vehicles may experience a "Malfunction Indicator Lamp (MIL) illumination" on their dashboard. This warning light typically indicates an issue with the Power Transfer Unit (PTU) system, often accompanied by specific diagnostic trouble codes (DTCs) stored in the vehicle's computer. The root cause of this Jeep Compass PTU failure is identified as moisture.
Diagnostic Trouble Codes (DTCs)
When diagnosing a Jeep Compass PTU failure, technicians may find one or more of the following DTCs:
| Code | Description |
|---|---|

Repair Procedure Summary
Technical Service Bulletin 21-057-24 outlines a diagnostic and repair process for the Jeep Compass PTU failure. The procedure begins with using a wiTECH scan tool to confirm the presence of the relevant DTCs.
- Initial Inspection: Technicians will inspect the connector pins at both the PTU and the shift actuator wire harness for any evidence of moisture. Figure 1 in the TSB illustrates these wire harness connectors.
- Wire Harness Replacement: If moisture is found, the wire harness is replaced. After replacement, any stored DTCs are cleared, and the vehicle is road-tested for 5-6 miles (8-10 km). If DTCs reappear, further steps are necessary.
- Shift Actuator Removal: If DTCs persist after the wire harness replacement and road test, or if no moisture was initially found, the shift actuator is removed from the PTU.
- Intermediate Gear Inspection: The intermediate gear is then inspected for broken teeth, as shown in Figure 2 of the TSB.
- PTU or Shift Actuator Replacement:
- If broken teeth are found on the intermediate gear, the entire Power Transfer Unit (PTU) and its mating wire harness are replaced.
- If no broken teeth are found, the shift actuator and its mating wire harness are replaced.
- Final Steps: After any component replacement, all DTCs are cleared.
