B1415 — Power Window LR Motor Circuit Open
System: Body | Type: Manufacturer-Specific | Make: Generic
B1415 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 B1415 is stored, the module has detected an open (broken or disconnected) electrical path 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.
B1415 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.
The Body Control Module (BCM) or Door Control Module (DCM) monitors the left rear power window motor circuit and sets B1415 when an open or excessively high resistance is detected on one of the motor command outputs. The module commands the bidirectional window motor by switching battery voltage to one of the two motor terminals while grounding the other, and current senses the motor during operation to confirm a closed circuit. An open circuit fault means the module pulled the output high or low but saw no corresponding current flow, indicating a break in the wiring, a disconnected connector,...
