B103C MERCURY Description
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 Diagnostic Trouble Code (DTC) will be set: DTC B103C (Thermoelectric Driver Open Load) – If DCSM outputs to the driver seat backrest or cushion TED 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.
