DTC	Description	Source	Perform Test
B1342	ECU Is Faulted	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.
B1358	Ignition Switch or Blower Electronics Circuit Short to Ground	CCSM	Go To PINPOINT TEST J: DTC B1358 - IGNITION SWITCH OR BLOWER ELECTRONICS CIRCUIT SHORT TO GROUND/DTC B2521 - TACH CIRCUIT FAILURE .
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	CHECK circuit 1554 (WH) for a fault and REPAIR as needed. If okay, refer to BATTERY & CHARGING SYSTEM .
B2488	Thumb-Wheel Switch Voltage Out of Range High	CCSM	NOTE: Make sure CCSM C3031b (driver) or CCSM C3036b (passenger) pins 7 and 15 are open (no connect). If circuits are present at either pin location, repair the wiring concern. 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.
B2521	Tach Circuit Failure	CCSM	Go To PINPOINT TEST J: DTC B1358 - IGNITION SWITCH OR BLOWER ELECTRONICS CIRCUIT SHORT TO GROUND/DTC B2521 - TACH CIRCUIT FAILURE .
B2729	Cushion Over-Temp Detected	CCSM	For driver CCSM, Go To PINPOINT TEST K: DTC B2729 - CUSHION OVER-TEMP DETECTED/DTC B2730 - BACK OVER-TEMP DETECTED/DTC B2731 - DIFFERENTIAL TEMPERATURE FAULT - DRIVER SEAT . For passenger CCSM, Go To PINPOINT TEST L: DTC B2729 - CUSHION OVER-TEMP DETECTED/DTC B2730 - BACK OVER-TEMP DETECTED/DTC B2731 - DIFFERENTIAL TEMPERATURE FAULT - PASSENGER SEAT .
B2730	Back Over-Temp Detected	CCSM	For driver CCSM, Go To PINPOINT TEST K: DTC B2729 - CUSHION OVER-TEMP DETECTED/DTC B2730 - BACK OVER-TEMP DETECTED/DTC B2731 - DIFFERENTIAL TEMPERATURE FAULT - DRIVER SEAT . For passenger CCSM, Go To PINPOINT TEST L: DTC B2729 - CUSHION OVER-TEMP DETECTED/DTC B2730 - BACK OVER-TEMP DETECTED/DTC B2731 - DIFFERENTIAL TEMPERATURE FAULT - PASSENGER SEAT .
B2731	Differential Temperature Fault	CCSM	For driver CCSM, Go To PINPOINT TEST K: DTC B2729 - CUSHION OVER-TEMP DETECTED/DTC B2730 - BACK OVER-TEMP DETECTED/DTC B2731 - DIFFERENTIAL TEMPERATURE FAULT - DRIVER SEAT . For passenger CCSM, Go To PINPOINT TEST L: DTC B2729 - CUSHION OVER-TEMP DETECTED/DTC B2730 - BACK OVER-TEMP DETECTED/DTC B2731 - DIFFERENTIAL TEMPERATURE FAULT - PASSENGER SEAT .
B2792	Heat Switch Short to Ground	CCSM	NOTE: Make sure CCSM C3031b (driver) or CCSM C3036b (passenger) pin 6 are open (no connect). If circuits are present at either pin location, repair the wiring concern. 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.
B2793	Cool Switch Short to Ground	CCSM	NOTE: Make sure CCSM C3031b (driver) or CCSM C3036b (passenger) pin 16 are open (no connect). If circuits are present at either pin location, repair the wiring concern. 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.
U2362	UBP Invalid Data Node ID	CCSM	NOTE: DTC U2362 indicates a network concern, the CCSM is not the 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 to MODULE COMMUNICATIONS NETWORK .
