What Does DTC P2177 Mean in a Buick?

The diagnostic trouble code (DTC) P2177 in a Buick typically points to an issue with the thermoelectric system in the driver’s seat. Specifically, this code is set when the Seat Climate Module Electronics (SCME) detects a short to ground or a resistance value lower than 0.9 ohms in the blower motor circuit for either the backrest or cushion. To prevent further issues, the system shuts down and triggers this code for safety.

Common Causes of Code P2177

Short circuit to ground in the blower motor wiring
Faulty seat blower motor with high current draw
Corroded or damaged connectors in the seat climate system
Malfunctioning Seat Climate Module Electronics (SCME)
Blown fuse or faulty relay in the seat power system
