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 SRS. Refer to Supplemental Restraint System (SRS) Depowering and Repowering in the General Procedures portion of AIR BAG RESTRAINT SYSTEMS . DISCONNECT driver seat side air bag C316 or passenger seat side air bag C314 of the affected seat and CONNECT restraint system diagnostic tool 418-133 or 501 -097 to the seat side air bag module body harness connector. CONNECT the battery ground cable. CHECK circuit 20-HC21 (PK/BK) (driver) or circuit 20-HC22 (PK/YE) passenger for a fault and REPAIR as needed. If okay, REFER to GENERATORS & REGULATORS .Once the repair is complete, DISCONNECT the restraint system diagnostic tool from the seat side air bag module body harness connector and CONNECT the seat side air bag module connector of the affected seat. REPOWER the SRS. REFER to AIR BAG RESTRAINT SYSTEMS .

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.
