Front Seats — 2016 workshop reference 1030

DTC B111C

Refer to Wiring Diagrams Cell 119 for schematic and connector information.

Normal Operation and Fault Conditions

The SCME monitors the backrest and cushion blower motor circuits. If an open on any of these circuits is detected, the DTC will be set.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Conditions
	B111C Passenger Thermoelectric Driver Open Load	If SCME outputs to the passenger seat backrest or cushion blower motor (circuit pins A, B, C or D at the SCME connector) or any components within these circuit loops are open, disconnected or a blower motor resistance greater than 90,000 ohms is sensed, the SCME continues normal operation and sets this DTC.
