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 double door lock ECU receives rear left side door double door lock set/release signals from the main body ECU RH using multiplex communication.
The double door lock ECU controls the double lock motor to set/release the double door lock. This ECU 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.
