POWER SEATS CLIMATE CONTROLLED SEAT MODULE (CCSM) DIAGNOSTIC TROUBLE CODE (DTC) LIST
| DTC | Description | Source | Perform Test |
|---|---|---|---|
| B1342 | ECU Is Faulted | CCSM | INSTALL a new CCSM and CARRY OUT programmable module installation (PMI). REFER to CLIMATE CONTROLLED SEAT MODULE . |
| B1358 | Ignition Switch or Blower Electronics Circuit Short to Ground | CCSM | Go To PINPOINT TEST P . |
| 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 CONFIGURATION . 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 safety belt buckle pretensioner C3201 or passenger safety belt buckle pretensioner C3202 of the affected seat and CONNECT restraint system diagnostic tool 418-133 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 | Thumb-Wheel Switch Voltage Out of Range High | CCSM | Go To PINPOINT TEST P . |
| B2521 | Tach Circuit Failure | CCSM | Go To PINPOINT TEST P . |
| B2729 | Cushion Overtemp Detected | CCSM | Go To PINPOINT TEST P . |
| B2730 | Back Overtemp Detected | CCSM | Go To PINPOINT TEST P . |
| B2731 | Differential Temperature Fault | CCSM | Go To PINPOINT TEST P . |
| 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 C3201 or passenger safety belt buckle pretensioner C3202 of the affected seat and CONNECT restraint system diagnostic tool 418-133 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 C3201 or passenger safety belt buckle pretensioner C3202 of the affected seat and CONNECT restraint system diagnostic tool 418-133 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. REPOWER the SRS. REFER to AIR BAG RESTRAINT SYSTEMS
