Rear Door Lock Motor RH Circuit

DESCRIPTION

The rear right side door lock motor is built into the rear right side door lock assembly.
The main body ECU RH controls the rear right side door lock motor to lock/unlock the rear right side door. This ECU applies current from terminal ACT+ to terminal ACT- to operate the motor to lock the door. It reverses the direction of the current flow to operate the motor to unlock the door.
