Details of the b0025 OBD Code
B0025 code indicates a problem with the left side airbag deployment loop.
OBD code B0025 means Left Side Deployment Loop Resistance Low.
This code is triggered by the sensing and diagnostic module (SDM) when it detects a low resistance in the deployment loop circuit on the left side airbag system.
The deployment loop is part of the airbag system that includes the airbag module, impact sensors, and wiring that deploy the airbag in the event of a crash.
When the resistance in this circuit is lower than specified, the B0025 code is set, indicating a potential issue with the left side airbag system.
