Opening The Trunk Lid/Tailgate
The tailgate/trunk lid can be opened in three ways:
- via the switch on the tailgate/trunk lid if the vehicle is unlocked
- via the button on the remote key
- keyless
- lock button.
The tailgate/trunk lid can be "unlocked" separately using a switch on the light switch module (LSM). When the switch is pressed in, a signal is transmitted to the central electronic module (CEM) indicating that the tailgate/trunk lid must permitted to be opened using the switch in the handle on the lid.
If the unlocking switch for the tailgate/boot lid on the light switch module (LSM) is pressed in there is no feedback to the driver. That is, nothing will be heard or seen that indicates that the tailgate/boot lid has been "unlocked".
The lock motor for the tailgate/trunk lid is directly connected to the central electronic module (CEM).
The switch on the tailgate/trunk lid is directly connected to the central electronic module (CEM).
When the switch is pressed in, the central electronic module (CEM) transmits a message to the keyless vehicle module (KVM), which activates the antenna in the bumper and begins checking for an authorized remote key using keyless functionality. If an authorized remote key is found, the keyless vehicle module (KVM) transmits a signal to the central electronic module (CEM) to activate the lock motor in the trunk lid or tailgate. The tailgate/trunk lid is not opened if valet locking is activated.
There is no "unlocked" position for the lock motor for the tailgate/trunk lid. When the motor is activated, it releases the catch in the body and the tailgate/trunk lid can be opened. The tailgate/trunk lid locks when it is closed again. When the tailgate/trunk lid is to be opened, the lock motor is powered for approximately 0.5 seconds or until the central electronic module (CEM) receives a signal from the door open contact breaker in the lock motor indicating that it is open. If the trunk lid/tailgate is not indicated as open during this time, a diagnostic trouble code (DTC) is stored in the central electronic module (CEM).
The button on the remote key can be used to unlock the tailgate/trunk lid even if the rest of the vehicle is locked.
There is also a function for activating the lock motor via the remote key or switch on Light switch module (LSM).
