About B1425

B1425 is a manufacturer-specific body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1425 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

B1425 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The Body Control Module (BCM) or Door Control Module (DCM) controls the right rear power window motor through driver outputs that reverse polarity to operate the window up or down. DTC B1425 sets when the module detects that the motor control circuit is shorted to ground, typically by monitoring voltage or current feedback on the output stage. Causes commonly include chafed wiring inside the rear door hinge boot, water intrusion at the rear door connector, internal motor faults, or a sticking window switch holding the circuit grounded. When this code is set, the right rear window may fail to o...
