S11 DETERMINE CUSHION BLOWER MOTOR OR SCME (FRONT SEAT CLIMATE CONTROL MODULE) FAILURE
- Remove the cushion blower motor from the passenger seat. Refer to: Front Seat Cushion Blower Motor .
- Remove the cushion blower motor from the driver seat and install it on the passenger seat.
- Connect: Passenger Cushion Blower Motor C3040 .
- Connect: DSM C341D and C341E .
- Start the engine and check operation of the passenger seat climate controlled seat system.
Does the seat operate with the cushion blower motor from the other seat installed?

Yes INSTALL a new seat cushion blower motor. REFER to: Front Seat Cushion Blower Motor . GO to S13

No GO to S12

S12 CHECK THE SCME (FRONT SEAT CLIMATE CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect and inspect all of the DSM connectors.

Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins as necessary
- pushed-out pins - install new pins as necessary

Reconnect the DSM connectors. Make sure they seat and latch correctly.

NOTE: Do not reconnect Driver Side Airbag In-Line C3368 or Passenger Side Airbag In-Line C3206 at this time.

Reconnect all previously disconnected connectors.

Ignition ON.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes	CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new DSM. Refer to: Driver Front Seat Module (DSM) . GO to S13

No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues. GO to S13

S13 CHECK FOR SRS (SUPPLEMENTAL RESTRAINT SYSTEM) DIAGNOSTIC TROUBLE CODES (DTCS)
- WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.
  
  Ignition OFF.
- Connect: Driver Side Airbag In-line C3368 .
- Connect: Passenger Side Airbag In-line C3206 .
- Connect all previously disconnected connectors.
- Ignition ON.
- Using a diagnostic scan tool, clear the RCM Diagnostic Trouble Codes (DTCs).
- Cycle the ignition OFF then ON.
- Using a diagnostic scan tool, perform RCM self-test.
Are any RCM Diagnostic Trouble Codes (DTCs) retrieved during self-test?

Yes REFER to: Supplemental Restraint System (Except Hybrid) .
