WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
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 will be set:
- DTC B103C (Thermoelectric Driver Open Load) - If DCSM outputs to the driver seat backrest or cushion TED (circuit pin G, H, J or K 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
