At the ignition switch, check the correctness of the contact closure in different positions of the ignition key (Table 9.4), the operation of the anti-theft device and the presence of communication with the vehicle anti-theft system. Voltage from the battery and generator is supplied to contact "30"
To relieve the ignition switch contacts, relay K4 is installed in the mounting block.
The anti-theft device locking rod extends when the ignition key is set to position "0" (off) and removed from the ignition switch. The locking rod is recessed after turning the key from position "0" (off) to position "I" (ignition). The key can only be removed from the ignition switch in position "0".
The starter re-engagement interlock must not allow the key to be turned again from position "I" (ignition) to position "II" (starter). Such a turn must only be possible after the key has returned to position "0" (off).
