DTC	Description	Source	Action
B1342	ECU Is Faulted	CCSM	INSTALL a new CCSM and CARRY OUT programmable module installation (PMI). REFER to FRONT SEAT CUSHION .
B1358	Ignition Switch or Blower Electronics Circuit Short to Ground	CCSM	For driver CCSM, Go To PINPOINT TEST J . For passenger CCSM, Go To PINPOINT TEST K .
B2477	Module Configuration Error	CCSM	This DTC indicates programmable module installation (PMI) has not been done to a newly installed module. CARRY OUT PMI. REFER to MODULE COMMUNICATIONS NETWORK . CLEAR the DTC. CARRY OUT the self-test.
B2486	Climate Controlled Seat Module Voltage Out of Range	CCSM	DEPOWER the supplemental restraint system (SRS). REFER to AIR BAG RESTRAINT SYSTEMS . DISCONNECT driver seat C327 or passenger seat C315 of the affected seat and CONNECT restraint system diagnostic tool 501-095 to the affected seat connector. CONNECT the battery ground cable. CHECK circuit 294 (WH/LB) for a fault and REPAIR as needed. If OK, REFER to BATTERY & CHARGING SYSTEM . Once the repair is complete, DISCONNECT the restraint system diagnostic tool from the seat connector and CONNECT the seat connector of the affected seat. REPOWER the SRS. REFER to AIR BAG RESTRAINT SYSTEMS .
B2488	Thumb-Wheel Switch Voltage Out of Range High	CCSM	For driver CCSM, Go To PINPOINT TEST J . For passenger CCSM, Go To PINPOINT TEST K .
B2521	Tach Circuit Failure	CCSM	For driver CCSM, Go To PINPOINT TEST J . For passenger CCSM, Go To PINPOINT TEST K .
B2729	Cushion Over-Temp Detected	CCSM	For driver CCSM, Go To PINPOINT TEST J . For passenger CCSM, Go To PINPOINT TEST K .
B2730	Back Over-Temp Detected	CCSM	For driver CCSM, Go To PINPOINT TEST J . For passenger CCSM, Go To PINPOINT TEST K .
B2731	Differential Temperature Fault	CCSM	For driver CCSM, Go To PINPOINT TEST J . For passenger CCSM, Go To PINPOINT TEST K .
B2792	Heat Switch Short to Ground	CCSM	NOTE: If HEAT is pressed for greater than 20 seconds on the climate controlled seat switch, DTC B2792 will set in the CCSM. CLEAR the DTC. If the DTC does not clear, DEPOWER the supplemental restraint system (SRS). REFER to AIR BAG RESTRAINT SYSTEMS . DISCONNECT driver seat C327 or passenger seat C315 of the affected seat and CONNECT restraint system diagnostic tool 501-095 to the affected seat connector. CONNECT the battery ground cable. CHECK circuit 1551 (VT/WH) for a fault and REPAIR as needed. If OK, INSTALL a new climate controlled seat switch. Once the repair is complete, DISCONNECT the restraint system diagnostic tool from the seat connector and CONNECT the seat connector of the affected seat. REPOWER the SRS. REFER to AIR BAG RESTRAINT SYSTEMS .
B2793	Cool Switch Short to Ground	CCSM	NOTE: If COOL is pressed for greater than 20 seconds on the climate controlled seat switch, DTC B2793 will set in the CCSM. CLEAR the DTC. If the DTC does not clear, DEPOWER the supplemental restraint system (SRS). REFER to AIR BAG RESTRAINT SYSTEMS . DISCONNECT driver seat C327 or passenger seat C315 of the affected seat and CONNECT restraint system diagnostic tool 501-095 to the affected seat connector. CONNECT the battery ground cable. CHECK circuit 1550 (WH/OG) for a fault and REPAIR as needed. If OK, INSTALL a new climate controlled seat switch. Once the repair is complete, DISCONNECT the restraint system diagnostic tool from the seat connector and CONNECT the seat connector of the affected seat. REPOWER the SRS. REFER to AIR BAG RESTRAINT SYSTEMS .
U2362	UBP Invalid Data Node ID	CCSM	NOTE: DTC U2362 indicates a network concern, the CCSM is not the source of the fault. CLEAR the DTC. If the DTC does not clear, REFER MODULE COMMUNICATIONS NETWORK .
