Lock Units Side Doors
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2013 Volvo C70, 2012 Volvo C70, 2011 Volvo C70, 2010 Volvo C70, and 2009 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.
The lock units (3/74-77) are in the doors and are directly connected to the door control module in the relevant door.
There are different versions of the lock units, depending on the configuration of the lock motors.
There are two versions of the lock units in the front doors with lock motors for:
- central locking
- central locking and deadlocking.
The central locking lock motor locks the door.
The door control modules can only unlock the doors on receipt of a command from the central electronic module (CEM). In addition to the lock motors, the lock units contain up to three contract breakers depending on the configuration:
- contact breaker to indicate that the central locking motor is in the locked position
- contact breaker to indicate that the door is in the latch position (not fully closed)
The lock motors have built in overheating protection which prevents the motor from activating if there is a risk of the motor getting too hot.
