CLIMATE CONTROLLED SEAT MODULE (CCSM) DIAGNOSTIC TROUBLE CODE (DTC) LIST

DTC	Description	Source	Perform Test
B1342	ECU Is Faulted	CCSM	INSTALL a new CCSM.
B1358	Ignition Switch or Blower Electronics Circuit Short to Ground	CCSM	Go To PINPOINT TEST U: 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.
B2488 .The presence of this DTC indicates the module is not configured correctly.	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 U: 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 V: 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 W: 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 V: 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 W: 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 V: 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 W: DTC B2729 -- CUSHION OVER-TEMP DETECTED/DTC B2730 -- BACK OVER-TEMP DETECTED/DTC B2731 -- DIFFERENTIAL TEMPERATURE FAULT -- PASSENGER SEAT .
B2792 ^b	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 ^b	Cool Switch Short to Ground	CCSM	NOTE: Make sure CCSM C3031b (driver) or CCSM C3036b (passenger) pin 16 is open (no connect). If circuit is present at either pin location, repair the wiring concern. For driver CCSM, Go To PINPOINT TEST V: 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 W: DTC B2729 -- CUSHION OVER-TEMP DETECTED/DTC B2730 -- BACK OVER-TEMP DETECTED/DTC B2731 -- DIFFERENTIAL TEMPERATURE FAULT -- PASSENGER SEAT .
