CLIMATE CONTROLLED SEAT MODULE DIAGNOSTIC TROUBLE CODE LIST

DTC	Description	Source	Perform Test
B1342	ECU Is Faulted	CCSM	CONFIGURE the CCSM. CLEAR the DTC. If does not clear, CONFIGURE the CCSM once again. CLEAR the DTC. If the DTC does not clear, INSTALL a new CCSM.
B1358	Ignition Switch or Blower Electronics Circuit Short to Ground	CCSM	Go To PINPOINT TEST Q .
B2477	Module Configuration Error	CCSM	CONFIGURE the CCSM. CLEAR the DTC. If the DTC does not clear, CONFIGURE the CCSM once again. CLEAR the DTC. If the DTC does not clear, INSTALL a new CCSM.
B2486	Climate Controlled Seat Module Voltage Out of Range	CCSM	DEPOWER the supplemental restraint system (SRS). REFER to AIR BAG RESTRAINT SYSTEMS . DISCONNECT driver safety belt buckle pretensioner electrical connector or passenger safety belt buckle pretensioner electrical connector of the affected seat and CONNECT restraint system diagnostic tool 418-F395 to the safety belt buckle pretensioner harness connector. CONNECT the battery ground cable. CHECK circuit 294 (WH/LB) for a fault. REPAIR as needed. If okay, REFER to BATTERY, MOUNTING AND CABLES . Once the repair is complete, DISCONNECT the restraint system diagnostic tool from the safety belt buckle pretensioner harness connector and CONNECT the safety belt buckle pretensioner connector of the affected seat. REPOWER the SRS. REFER to AIR BAG RESTRAINT SYSTEMS .
B2488	Thumbwheel Switch Voltage Out of Range High	CCSM	Go To PINPOINT TEST R
B2521	Tach Circuit Failure	CCSM	Go To PINPOINT TEST Q .
B2729	Cushion Over-Temp Detected	CCSM	Go To PINPOINT TEST S .
B2730	Back Over-Temp Detected	CCSM	Go To PINPOINT TEST S .
B2731	Differential Temperature Fault	CCSM	Go To PINPOINT TEST S .
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 safety belt buckle pretensioner electrical connector or passenger safety belt buckle pretensioner electrical connector of the affected seat and CONNECT restraint system diagnostic tool 418-F395 to the safety belt buckle pretensioner harness connector. CONNECT the battery ground cable. CHECK circuit 1551 (VT/WH) for a short to ground. REPAIR as needed. If okay, INSTALL a new climate controlled seat switch. Once the repair is complete, DISCONNECT the restraint system diagnostic tool from the safety belt buckle pretensioner harness connector and CONNECT the safety belt buckle pretensioner 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 safety belt buckle pretensioner electrical connector or passenger safety belt buckle pretensioner electrical connector of the affected seat and CONNECT restraint system diagnostic tool 418-F395 to the safety belt buckle pretensioner harness connector. CONNECT the battery ground cable. CHECK circuit 1550 (WH/OG) for a short to ground. REPAIR as needed. If okay, INSTALL a new climate controlled seat switch. Once the repair is complete, DISCONNECT the restraint system diagnostic tool from the safety belt buckle pretensioner harness connector and CONNECT the safety belt buckle pretensioner connector of the affected seat RFPOWFR the SRS REFER to AIR BAG RESTRAINT SYSTEMS .
U2362	UBP Invalid	CCSM	NOTE: DTC U2362 indicates a network concern, the CCSM is not the Data Node ID source of the fault. CONFIGURE the CCSM. CLEAR the DTC. If the DTC does not clear, CONFIGURE the CCSM once again. CLEAR the DTC. If the DTC does not clear, REFER MODULE CONFIGURATION .
