Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Unlocking The Trunk Lid/Tailgate
In practice there is no "locked" mode for the lock on the tailgate/trunk lid. The difference between locked and unlocked is whether the central electronic module (CEM) will activate the lock motor or not when the switch on the tailgate/trunk lid is pressed.
The tailgate/trunk lid is "locked" and "unlocked" at the same time as other doors if an unlock command is received from the remote control. The tailgate/trunk lid can also be unlocked separately using a dedicated button on the remote control.
The switch on the tailgate or trunk lid is directly connected to the keyless vehicle module (KVM) and to the central electronic module (CEM). The lock motor is directly connected to the central electronic module (CEM).
Applies to the C70:
To access the cargo compartment when, for example, the vehicle has no power, there is a lock cylinder on the left-hand side front edge of the rear seat, which is mechanically connected to the cargo compartment lock.
