from being opened from the inside
regardless of lock-button position.
The General Module (GM V) and
Electronic Immobilization (EWS 3.3)
interface via the K-bus to monitor
double lock status and to initiate
double lock override. This feature
allows the doors to be opened from the
inside if a key accepted by EWS is
switched on in the ignition when the
doors are double locked.
Continuous locking/unlocking will
initiate a timed arrest of the locking
system. The GM V counts each time
the locks are actuated. After
approximately 12 cycles, the timed
arrest is active. The timed arrest is
deactivated one actuator cycle for every
8 seconds until the counter is reset to
0. The timed arrest is overridden if a
crash signal is received from the
multiple restraint system (MRS).
