Keyless Function
If there is a keyless entry system, the keyless vehicle module (KVM) checks the identity of the remote key during locking and unlocking. After checking the key identity, the keyless vehicle module (KVM) then transmits a command to the central electronic module (CEM) to lock or unlock the central locking. To reduce response time when unlocking, first the keyless vehicle module (KVM) sends an unlock command to relevant door control module. Keyless vehicle module (KVM) uses the antennas in the outer handles on the side doors and in the rear bumper to check the identity of the remote key.
Check of the remote key is done when one of the lock or unlock sensors on the outer door handles or the lock or unlock button on the tailgate is activated. Keyless vehicle module (KVM) then activates one of the outer antennas to check the remote key's identity.
The vehicle is locked using the lock sensors on the door handles or with lock button on the tailgate. During locking, the antenna is also activated to check that there is an authorized remote key in the vicinity of the vehicle. If the remote key is approved, the keyless vehicle module (KVM) transmits a signal to the central electronic module (CEM) to lock the vehicle.
