2021-2025 Jeep Compass Turtle Icon Warning, No EV Operation

Symptoms

Owners of 2021-2025 Jeep Compass and Renegade vehicles may experience a Jeep Compass Turtle Icon Warning lamp illuminated on the instrument cluster. This warning is typically accompanied by a complete loss of electric vehicle operation and/or the inability to engage reverse gear. Technicians may also observe a malfunction indicator lamp (MIL) illuminated.

Important Warnings

Owners and technicians should be aware of a critical advisory related to this issue:

• "Please note that Electric mode unavailability and/or reverse gear unavailability can be considered as a condition of DTCs P08F2/P08F3; no oil drain from transmission is necessary."

This means that if you are experiencing these symptoms and the related DTCs, replacing the transmission fluid is not the solution and should not be performed.

Fault Codes / DTCs

The following Diagnostic Trouble Codes (DTCs) may be observed in various control modules, indicating issues related to the electric drive system and its components. These codes are crucial for diagnosing the Jeep Compass Turtle Icon Warning.

Diagnosis and Repair Procedure Summary

This Stellantis STAR Online Publication, Case Number S2408000117, outlines a diagnostic and repair process for the Jeep Compass Turtle Icon Warning and related electric drive system issues. The procedure emphasizes thorough electrical checks before considering major component replacements.

1. Initial DTC Verification: Begin by checking for any additional DTCs present in the Powertrain Control Module (PCM), Battery Pack Control Module (BPCM), Hybrid Control Processor (HCP), or Auxiliary Power Module (APM). While multiple codes may be present, they might not all appear simultaneously.
2. Battery State of Charge Check: Verify the 12V and 48V battery states of charge. Recharge if necessary.
3. Wiring and Connection Verification: Conduct a detailed inspection of the wiring and connections, particularly focusing on the 12V and 48V circuit. This includes inspecting the wiring harness between the 48V battery and the electric motor, and checking the 330A fuse located in a blue box. Ensure all nuts at the connections of the 48V battery and the inverter are properly tightened. Specific tightening torques are 16 Nm (±10%) for inverter, DCDC, and battery connections, and 11 Nm for the 48V fuse top and bottom.
4. Related DTC Diagnosis: If any DTCs are present after the initial checks, diagnose and resolve those issues before proceeding with the P08F3 diagnosis.
5. P08F3 Diagnosis: If no other codes are present, follow the specific P08F3 diagnosis procedure. Importantly, this procedure should be completed without immediately replacing the inverter or the transmission.
6. Inverter/Transmission Replacement: If the Hydraulic Control Processor (HCP) reports DTC P0DA3-00, which indicates a "Drive Motor 'B' Inverter Voltage Sensor 'A' Circuit" fault, replace only the inverter first. If the DTC persists after inverter replacement, then the entire transmission should be replaced.
7. Other DTCs: For any other DTCs not explicitly mentioned in this bulletin, follow the standard diagnostic procedures.

Required Tools or Parts

Technicians will require standard electrical diagnostic tools, including a multimeter for continuity and capacity checks, and a torque wrench to ensure proper tightening of electrical connections. No specific special tools or part numbers are listed beyond the inverter and transmission themselves, which are replaced only if specific conditions are met.

Owner Action

If your 2021-2025 Jeep Compass or Renegade is displaying a "Turtle Icon Warning Lamp" or experiencing a loss of electric vehicle operation or reverse, it is recommended to schedule an appointment with an authorized Stellantis dealer. They have access to the specific diagnostic procedures outlined in TSB S2408000117 to accurately diagnose and repair the issue.
