Pinpoint Test Ad : DTC B103D: Notes

Pinpoint Test AD: DTC B103D 

Refer to Wiring Diagrams Climate Controlled Seats for schematic and connector information.

Normal Operation 

The Dual Climate Controlled Seat Module (DCSM) monitors the driver seat blower circuits. If a short to ground on any of these circuits is detected, the DTC will be set.

• DTC B103D (Blower Driver Overtemperature) - If the DCSM output circuits to the driver seat blowers or any components within these circuit loops are shorted to ground or cause an excessive current draw, the DCSM will overheat, shut down the driver seat system and set this DTC.

This pinpoint test is intended to diagnose the following: 

• Wiring, terminals or connectors
• Thermo-Electric Device (TED) assembly
• DCSM
