Type A: Positive-Triggered, Relay-Driven System - Viper 480XV Installation Manual

Type A: Positive-Triggered, Relay-Driven System

The system can control Type A door locks directly, with no additional parts. The switch will have
three wires on it; one will test (+)12 volt constantly. The others will alternately pulse (+)12 volt
when the switch is pressed to the lock or unlock position.
If you cannot get to the switch, and you find a set of wires that pulse (+)12 volt alternately on lock
and unlock, make sure that it is not a Type C direct-wire system.
Cut the wire that pulses (+)12 volt on lock, and then operate the switch to unlock.
➤ ➤
If all doors unlock, the vehicle uses type A system.
➤ ➤
If you lose all door lock operation in both directions, you are operating the master switch in a
Type C system.
➤ ➤
If you lose all door lock operation of one or more, but not all motors, and other doors still work,
you have cut a wire leading directly to one or more motors. You must instead find the actual
wires leading to the switch.
IMPORTANT! Remember that these wires' functions reverse between Type A and
Type B.
