Details of the b2175 OBD Code
B2175 code indicates a malfunction in the steering wheel audio control switch circuit.
OBD code B2175 means Seat Track Position Switch Circuit Short to Ground.
This code is triggered by the Body Control Module (BCM) when it detects a short to ground in the circuit of the seat track position switch.
The seat track position switch is part of the power seat system and is used to determine the position of the seat for adjustment.
When a short to ground is detected in this circuit, the BCM sets code B2175 to indicate the issue with the seat track position switch circuit.
Mechanic’s Tech Notes
Code B2175 relates to the ignition switch position circuit being out of range.
To diagnose and fix OBDII code B2175, start by checking the Transmission Control Module (TCM) power and ground using a multimeter.
Verify TCM communication over the Controller Area Network (CAN) network with a scan tool.
If the TCM does not respond, reprogramming or reflashing may be necessary.
Visually inspect the wiring harness and connectors for any damage, and check connector pins for signs of being broken, bent, pushed out, or corroded.
This thorough inspection can help identify and resolve the issue causing the B2175 fault code.
