1. TEST FOR INTERMITTENT CONDITION NOTE: Make sure the battery is fully charged and the charging system is operating properly before proceeding. Turn the ignition on. With the scan tool, record and erase Diagnostic Trouble Codes (DTCs). Turn the ignition off. Start the engine and let it run. Turn the HSW on. With the scan tool, read DTCs. Is the DTC active? Yes Go To 2 . No The conditions that caused this code to set are not present at this time. Verify seat harness is routed correctly to the HSM. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals. Attempt to reproduce condition by rotating the steering wheel. Attempt to reproduce condition by adjusting the seat. Perform the BODY VERIFICATION TEST. Refer to «BODY VERIFICATION TEST»(ref-457926-S40044966262012030200000) for 1500, 2500 & 3500, or «BODY VERIFICATION TEST»(ref-457927-S20352278932012030200000) for 3500 CAB & CHASSIS, 4500 & 5500 .
2. CHECK FOR SHORTED (C91) HEATED STEERING WHEEL FEED CIRCUIT BETWEEN CLOCKSPRING AND HSM WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury. Disconnect the Clockspring C5 harness connector. WARNING: Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury. With the scan tool, erase DTCs. Start the engine and let it run. Turn the HSW on. With the scan tool, read DTCs. Is the same DTC active? Yes Go To 3 . No Go To 5 .
3. CHECK (C91) HEATED STEERING WHEEL FEED CIRCUIT FOR A SHORT TO GROUND Turn the ignition off. Disconnect the HSM C4 harness connector. NOTE: Check connectors. Clean and repair as necessary. Measure the resistance of the (C91) Heated Steering Wheel Feed circuit between ground and the Clockspring C5 harness connector. Is the resistance below 10k Ohms? Yes Repair the short to ground in the (C91) Heated Steering Wheel Feed circuit. Perform the BODY VERIFICATION TEST. Refer to «BODY VERIFICATION TEST»(ref-457926-S40044966262012030200000) for 1500, 2500 & 3500, or «BODY VERIFICATION TEST»(ref-457927-S20352278932012030200000) for 3500 CAB & CHASSIS, 4500 & 5500 . No Go To 4 .
4. CHECK (C91) HEATED STEERING WHEEL FEED CIRCUIT FOR A SHORT TO THE (C986) HEATED STEERING WHEEL RETURN CIRCUIT Measure the resistance between the (C91) Heated Steering Wheel Feed circuit and the (C986) Heated Steering Wheel Return circuit at the Clockspring C5 harness connector. Is the resistance below 10k Ohms? Yes Repair the short between the (C91) Heated Steering Wheel Feed circuit and the (C986) Heated Steering Wheel Return circuit. Perform the BODY VERIFICATION TEST. Refer to «BODY VERIFICATION TEST»(ref-457926-S40044966262012030200000) for 1500, 2500 & 3500, or «BODY VERIFICATION TEST»(ref-457927-S20352278932012030200000) for 3500 CAB & CHASSIS, 4500 & 5500 . No Replace the Heated Seat Module (HSM) in accordance with the Service Information. Perform the BODY VERIFICATION TEST. Refer to «BODY VERIFICATION TEST»(ref-457926-S40044966262012030200000) for 1500, 2500 & 3500, or «BODY VERIFICATION TEST»(ref-457927-S20352278932012030200000) for 3500 CAB & CHASSIS, 4500 & 5500 .
5. CHECK FOR A SHORTED HSW WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury. Remove the Driver Airbag in accordance with the Service Information. Disconnect the CLOCKSPRING C5 connector. NOTE: Before proceeding, thoroughly inspect the wiring harness and connectors between the HSW and the Clockspring. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals. Reconnect the CLOCKSPRING C5 harness connector. WARNING: Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury. With the scan tool, erase DTCs. Turn the ignition off. Start the engine and let it run. Turn the HSW on. With the scan tool, read DTCs. Is the same DTC active? Yes Replace the Clockspring in accordance with the Service Information. Perform the BODY VERIFICATION TEST. Refer to «BODY VERIFICATION TEST»(ref-457926-S40044966262012030200000) for 1500, 2500 & 3500, or «BODY VERIFICATION TEST»(ref-457927-S20352278932012030200000) for 3500 CAB & CHASSIS, 4500 & 5500 . No Replace the Heated Steering Wheel (HSW) in accordance with the Service Information. Perform the BODY VERIFICATION TEST. Refer to «BODY VERIFICATION TEST»(ref-457926-S40044966262012030200000) for 1500, 2500 & 3500, or «BODY VERIFICATION TEST»(ref-457927-S20352278932012030200000) for 3500 CAB & CHASSIS, 4500 & 5500 .
