B2311

DTC B2311 Driver's Seat Pulse Failure Abnormal Detection
DTC B2314 Passenger's Seat Pulse Failure Abnormal Detection

Circuit description

Operating the power window regulator master switch ASSY and the power window regulator switch ASSY drives the power window regulator motor ASSY RH (driver's seat) and power window regulator motor ASSY LH (passenger's seat). The power window regulator motor ASSY RH (driver's seat) and power window regulator motor ASSY LH (passenger's seat) have motor function and regulator function.

B2311 or B2314 is generated when any failure is detected inside the power window regulator motor ASSY RH (driver's seat) or the power window regulator motor ASSY LH (Passenger's seat), as well as when broken wire harness, short circuit, and/or improper connection of connector exists between the power window regulator switch and the power window regulator motor.

CAUTION:
- When replacing the power window regulator motor ASSY with new one or reusing its motor, perform the initialization of the power window system.
- Before performing the troubleshooting, check the fuse of this circuit.
