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.
NOTE:
Some BMW and VW vehicles will require the door lock output pulse to be
programmed (Menu 1, Feature 7) to 0.4 secs or the windows will either open or close
slightly when arming and disarming.
