B1476 — Wiper High Speed Circuit Motor Failure

System: Body  |  Type: Manufacturer-Specific  |  Make: Generic

About B1476

B1476 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 B1476 is stored, the module has detected a signal or supply voltage higher than the expected operating range.

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.

B1476 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 wiper control module monitors the high speed driver circuit that supplies current to the wiper motor's high speed brush tap or PWM input. DTC B1476 sets when the module commands the wiper motor to run at high speed but does not see the expected current draw, motor feedback, or park signal response, indicating the high speed circuit is open, shorted, or the motor itself has failed in that operating mode. Most wiper motors use two separate brush positions tapped from the same armature (a low speed brush and a high speed brush placed at different angular positions...
