WARNING: This page is about a different car, the 2013 RAM 3500 HD and 2013 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Vehicles equipped with the heated steering wheel option utilize a low voltage cut-off feature. This feature turns off power to the heated steering wheel anytime vehicle voltage is below 11.7 volts or above 15.5 volts. Be certain to check the vehicle electrical system for proper voltage anytime the heated steering wheel appears inoperative.

NOTE:

If a Diagnostic Trouble Code (DTC) can not be verified, it is a good indication that an INTERMITTENT fault condition may be present. To help find an intermittent problem, move the steering wheel around while testing continuity. also wiggle the heated steering wheel wire harness and electrical connectors while testing continuity.

NOTE:

For complete circuit diagrams, see Wiring Information. Wiring Information includes wiring diagrams, connector pin-out and location views, details of wire harness routing and retention, splice and ground locations and proper wire and connector repair procedures.

Before testing any individual components in the heated steering wheel system, check the following:

Check the ignition fuse in the Power Distribution Center (PDC). Repair as necessary.
Using a scan tool, check for any Diagnostic Trouble Codes (DTCs) related to the Heated Seat Module (HSM) and the U-Connect Touch ™ screen module. If any DTCs are found, repair as necessary . Refer to appropriate Electrical Diagnostics article.
Check the vehicles battery open-circuit voltage and charging system performance. If the vehicle's electrical system is defective or weak it may not be suppling sufficient energy to operate the heated steering wheel system.
If there are no DTCs and the heated steering wheel system functions properly, but the heated steering wheel indicator does not illuminate, the entire U-Connect Touch ™ screen module must be replaced.
