2026 Jeep Wrangler Heated Steering Wheel Not Working TSB 08-119-26

Symptoms

Owners of certain 2026 Jeep Wrangler vehicles may experience issues with their heated steering wheel. The primary symptom reported is that the "Heated Steering Wheel does not get hot enough or does not work." This can significantly impact comfort, especially in colder climates. This issue specifically affects the 2026 Jeep Wrangler.

Diagnosis

To diagnose this issue, technicians will use a Scan Tool (wiTECH) along with the appropriate Diagnostic Procedures available in DealerCONNECT/Service Library. They will verify that all related systems are functioning correctly. If any Diagnostic Trouble Codes (DTCs) or other symptom conditions, beyond the "Heated Steering Wheel does not get hot enough or does not work" issue, are present, these must be recorded and repaired before proceeding with the TSB 08-119-26 flash update.

Repair Procedure Summary

Technical Service Bulletin 08-119-26 outlines a software update for the Comfort Seat Wheel Module (CSWM) to resolve the heated steering wheel problem. The procedure involves:

1. Preparation: Install a battery charger to maintain voltage between 13.2 and 13.5 volts throughout the process. This prevents voltage drops that could interrupt the flash.
2. Reprogramming: Reprogram the CSWM with the latest available software using the wiTECH Diagnostic Application. If any issues occur during the flash, a ticket should be submitted to the Helpdesk.
3. DTC Clearance: After successful reprogramming, clear all Diagnostic Trouble Codes (DTCs) that may have been set in any module due to the reprogramming process. The wiTECH application will automatically display these DTCs for clearance.

Required Tools or Parts

The primary tool required for this repair is the wiTECH diagnostic system or an equivalent. No specific part numbers are listed for replacement, as the fix is a software update.

Important Warnings

• Battery Voltage: During the reprogramming process, it is critical to install a battery charger. Ensure the battery voltage does not drop below 13.2 volts and does not climb above 13.5 volts. Maintaining this specific voltage range is essential for a successful flash.
• Interruption: If the flash process is interrupted or aborted for any reason, it must be restarted from the beginning to ensure proper software installation.
