Function sequence
Unlocking vehicle with RF remote control
1 Basic prerequisites:
Driver's and passenger doors closed and locked.
2 The unlocking operation can be actuated with the "unlock" button on the radio frequency remote control (1).
3 The FFB control module (A43) receives the "unlock" signal and relays it to the ZV/KSA control module (A23).
4 The signal causes the ZV/KSA control module to actuate the locking motor (M11) in the driver's door and switch on the cab interior lighting. The locking motor in the driver's door moves to the "unlocked" position, the driver's door is unlocked and the interior lighting is switched on for max.
10 s (entry lamp/interior lamps on driver and passenger sides).
Only the driver's door is unlocked. The driver's door is locked again automatically if it is not opened within 25 s after unlocking.
The interior lighting goes out immediately when the ignition is switched on within 10 s. However, it remains switched on for a maximum of 5 minutes when one of the doors is opened and not closed again.
On vehicles equipped according to GGVS guidelines unlocking with the RF remote control is not possible. These vehicles have a battery isolation switch, which interrupts the entire power supply after switching off the ignition so that only mechanical unlocking is possible.
