Central Locking System Motor, Left Rear Door (184RL)

Location





Main task

^ Lock and unlock the door.
^ TSL locks the door (Theft Security Locking) (not US/CA).
^ With a switch, indicate if the door is open or closed, see Switch, left rear door (54RL)

Type

The central locking system motor, which is integrated in the door lock, has one electric motor version without TSL and 2 versions with TSL. The TSL motor has the task of controlling the ordinary lock motor in the locked position so that the door cannot be opened manually from the inside.

If for some reason the remote control does not work and the car is TSL locked, the front left door can still be opened using the mechanical emergency key. The polarity of the two motors is reversed to run them in the reverse direction. A switch indicates the status of the door and lock.

Connect

Electric motor

The motors are 2 pole and connected with their own separate wiring and common wiring to the door control module.

Switches

The switch has a ground and a signal lead connected to the door module. The door module feeds the switch with B+ via a resistor integrated in the control module. For the door the resistance is 100 k Ohms. The control module input is digital. A voltage greater than 2 V is interpreted as an open circuit, and lower than 2 V as a closed circuit.

NOTE: All cables in the wiring harness to the motor are black in order to impede car theft. The lock motor's connector has a guard to impede removal via the window channel.
