Toyota Corolla Cross (2022-2024) Service Manual / Vehicle Exterior / Window / Glass / Power Window Control System / RL-Door P/W Motor Component Internal Failure (B232096)

DESCRIPTION

The main body ECU (multiplex network body ECU) communicates with the power window regulator motor assembly (for rear LH door) via LIN communication.

This DTC is stored when a power window regulator motor assembly (for rear LH door) is malfunctioning, or the ECU built into the power window regulator motor assembly (for rear LH door) determines that the fully closed power window position has deviated approximately 20 mm (0.787 in.) or more from the normal position.

DTC No.
