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
