3. Operate the door lock switch/key cylinder in both directions to

determine the resistor values. If the multimeter displays zero

resistance in one direction, no resistor is needed for that direc-

tion.

4. Once the resistor value(s) is determined, refer to the wiring dia-

gram for proper wiring.

type H: negative (+) multiplex

The system is most commonly found in Ford, Mazda, Chrysler

and GM vehicles. The door lock switch or door key cylinder

may contain either one or two resistors.
