Details of the b2725 OBD Code
B2725 code indicates a malfunction in the driver’s door key cylinder switch circuit.
OBD code B2725 means the Park Brake Switch Circuit Low Voltage.
This code is triggered by the Body Control Module (BCM) when it detects a low voltage signal from the park brake switch circuit.
The park brake switch is typically located on the parking brake lever or pedal and sends a signal to the BCM to indicate when the parking brake is engaged or disengaged.
When the BCM receives a low voltage signal from the park brake switch circuit, it sets code B2725 to indicate a potential issue with the park brake switch or its circuit.
Mechanic’s Tech Notes
Code B2725 indicates a malfunction in the HVAC door actuator control circuit.
OBDII code B2725 indicates a communication issue with the transmission control module (TCM).
To diagnose, check TCM power and ground using a multimeter.
Use a scan tool to confirm TCM response over the CAN network.
Inspect wiring harness and connectors for damage, focusing on pin condition.
If no visible issues, consider TCM reprogramming.
Reflash the TCM if necessary.
This process helps ensure proper communication between the TCM and other vehicle systems.
