2025 Jeep Wrangler Clutch Warning TSB 18-056-25

Symptoms of PCM Software Issue

Owners of certain 2025 Jeep Wrangler vehicles may experience specific warnings or operational issues related to their vehicle's Powertrain Control Module (PCM). These symptoms are typically displayed on the Instrument Panel Cluster (IPC) and can include:

• The warning message "Clutch Hot" appearing.
• The warning message "Fully Release Clutch Pedal" appearing.
• The warning message "Reduce Clutch Use" appearing.
• The vehicle entering a "limp-in" state, which limits engine power and speed to prevent further damage.

These issues point to a problem with the PCM software, affecting the vehicle's performance and potentially its drivability. If you encounter a 2025 Jeep Wrangler clutch warning, it's important to address it promptly.

Diagnosis and Cause

The root cause of these symptoms is identified as an issue with the Powertrain Control Module (PCM) software. To diagnose the problem, technicians will use a Scan Tool, such as wiTECH, along with diagnostic procedures available in the DealerCONNECT/Service Library. They will verify that all related systems are functioning correctly. If any Diagnostic Trouble Codes (DTCs) or other symptom conditions are present beyond those listed in this bulletin, these must be recorded and addressed before proceeding with the PCM software update.

Repair Procedure Summary

The repair for the 2025 Jeep Wrangler clutch warning involves updating the PCM software. The process is straightforward but requires specific steps to ensure a successful flash:

1. Battery Stabilization: Before starting the reprogramming, a battery charger must be connected to the vehicle. This ensures the battery voltage remains between 13.2 and 13.5 volts throughout the flash process. Maintaining stable voltage is critical to prevent interruptions.
2. PCM Reprogramming: The technician will reprogram the Powertrain Control Module (PCM) with the latest available software using the wiTECH Diagnostic Application. If the flash process is interrupted or aborted for any reason, it must be restarted from the beginning.
3. DTC Clearing: After the PCM has been successfully reprogrammed, any Diagnostic Trouble Codes (DTCs) that may have been set in other modules due to the reprogramming process will be cleared. The wiTECH application will automatically present these DTCs for clearing.

This procedure, identified by Labor Operation Number 18-19-06-KC, typically takes approximately 0.3 hours of labor time.

Required Tools

To perform the PCM software update, technicians will need a wiTECH or equivalent diagnostic scan tool.

Important Notes for Technicians and Owners

• Battery Voltage: It is crucial to install a battery charger to ensure the battery voltage does not drop below 13.2 volts and does not exceed 13.5 volts during the flash process. Failure to do so can lead to an interrupted or failed update.
• Flash Interruption: If the PCM flash process is interrupted or aborted for any reason, the flash must be restarted from the beginning.
• Failure Code: Dealers must use failure code CC (Customer Concern) when processing claims related to this Technical Service Bulletin. This code is to be used specifically when the customer's concern matches the symptoms identified in TSB 18-056-25. When using failure code CC, the 3C's (customer's concern, cause, and correction) must be provided for processing.

Owner Action

If your 2025 Jeep Wrangler is exhibiting any of the described symptoms, such as a 2025 Jeep Wrangler clutch warning or entering a limp-in state, you should schedule an appointment with an authorized Jeep dealership. The repair involves a software update to the PCM and is reimbursable under the provisions of your vehicle's warranty.
