type G: positive (+) multiplex

This 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.

SSIINNGGLLEE--RREESSIISSTTOORR TTYYPPEE::

If one resistor is used in the door

lock switch/key cylinder, the wire will pulse (+)12V in one direc-

tion and less than (+)12V when operated in the opposite direction.

TTWWOO--RREESSIISSTTOORR TTYYPPEE::

If two resistors are used in the factory

door lock switch/key cylinder, the switch/key cylinder will read

less than (+)12V in both directions.

determine the resistor values, the door lock switch/key cylinder

must be isolated from the factory door lock system. For testing, use

a calibrated digital multimeter that is set to ohms.

note: Please refer to the Door Locking Systems document

(On-Line Tech Support, Tech

Tips) for complete resistor test procedure and additional

information for multiplexed door locks.

note: To ensure an accurate resistance reading, do not

touch the resistor or leads during testing.
