Rear Double Lock Motor LH Circuit

DESCRIPTION

The rear left side door double lock motor is built into the rear left side door lock assembly.
The door opening relay receives rear left side door double door lock set/release signals from the body ECU using multiplex communication.
The door opening relay controls the double lock motor to set/release the double door lock. This relay applies current from terminal ACTS to terminal ACTR to operate the motor to set the lock. It reverses the direction of the current to operate the motor to release the lock.
