Viper 600 ESP - One-Wire System, (Type F)

24 © 1999 Directed Electronics, Inc. Vista, CA
This system usually requires a negative pulse to unlock, and cutting the wire to lock the door. (With some vehi-
cles, these are reversed.) It is found in the late-model Nissan Sentra, some Nissan 240SX, and Nissan 300ZX
1992-up. It is also found in some Mazda MPV's.
IMPORTANT! Remember that the violet jumper between the #87 lock terminal and the #87 unlock
terminal must be cut.
