Pinpoint Test Bi : 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
