HEATED STEERING WHEEL

CAUTION: When equipped with a leather wrapped heated steering wheel and replacement of a Heated Seat Module (HSM) is required, the new HSM must be manually configured with a scan tool Programming and Relearning . Failure to follow these instruction may result in damage to the heated steering wheel.

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:

1. Check the fuse located in the Totally Integrated Power Module (TIPM). The fuse must be OK and tight in the receptacle.
2. Using a scan tool, check for any Diagnostic Trouble Codes (DTCs) related to the Heated Seat Module (HSM) and the heated steering wheel switch Testing and Inspection. If any DTCs are found, repair as necessary.
3. When equipped with a leather wrapped heated steering wheel, verify the HSM is configured to the leather steering wheel option, using a scan tool Programming and Relearning.
4. 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 supplying sufficient energy to operate the heated steering wheel system.
5. If there are no DTCs and the heated steering wheel system functions properly, but the Light Emitting Diode (LED) indicator in the switch does not illuminate, replace the instrument panel switch pod .
