Pinpoint Test Al : DTC B111C: Notes

Refer to Climate Controlled Seats , for schematic and connector information.

Normal Operation 

The seat cushion and backrest are equipped with a Thermo-Electric Device(TED) assembly that includes a seat blower (fan motor, serviced as an assembly with the TED). If the Dual Climate Controlled Seat Module(DCSM) detects an open circuit or high TED resistance, the following DTC sets:

• DTC B111C (Passenger Thermo-Electric Driver Open Load) - If the DCSM output circuits to the passenger seat backrest or cushion TED (circuit pins A, B, C or D at the DCSM connector) or any components within these circuit loops are open, disconnected or a TED resistance greater than 90, 000 ohms is sensed, the DCSM continues normal operation and sets this DTC.

This pinpoint test is intended to diagnose the following: 

• Wiring, terminals or connectors
• TED assembly
• DCSM
