Power Lock Switch

POWER LOCK SWITCH
The power lock switch circuitry is connected in series between ground and the driver door switch mux input of the instrument cluster (without memory). If equipped with the memory system, the circuitry is connected to the memory mirror module. Each power lock switch position (Lock, Unlock, and Neutral) provides a different resistance value to the instrument cluster or memory mirror input, which allows the instrument cluster or memory module to sense the switch position. Based upon the power lock switch input, the instrument cluster or memory module controls the battery and ground feed outputs to the individual power lock motors to lock or unlock the door latches. The Light-Emitting Diode (LED) in the power lock switch is connected to battery current through the power window circuit breaker in the Integrated Power Module (IPM) on a fused ignition switch output (run-acc) circuit so that the switch will be illuminated whenever the ignition switch is in the On or Accessory positions.
