Cause of the Issue

According to Technical Service Bulletin (TSB) 08-119-26, the root cause of the 2026 Jeep Wrangler heated steering wheel malfunction is related to the Comfort Seat Wheel Module (CSWM) software. An outdated or incorrect software version can prevent the heated steering wheel from operating as intended.

This involves using a diagnostic tool called wiTECH to reprogram the module with the latest available software. After the reprogramming is complete, any Diagnostic Trouble Codes (DTCs) that may have been set in other modules during the process will be cleared.

Required Tools or Parts

Important Warnings for Owners

• Battery Voltage During Update: During the software flash process, it is critical that the vehicle's battery voltage remains stable. Technicians are instructed to install a battery charger to ensure the voltage does not drop below 13.2 volts and does not climb above 13.5 volts. This precaution helps prevent issues during the update.
• Interrupted Flash: If the software flash process is interrupted or aborted for any reason, it must be restarted from the beginning to ensure proper module programming.
• Dealer Service Code: When addressing the "Heated Steering Wheel does not get hot enough or does not work" symptom, dealers are required to use failure code CC with TSB 08-119-26. This code helps track the specific repair and ensures proper warranty claim processing.
