E:: If two resistors are used in the factory
door lock switch/key cylinder, the door lock switch/key cylinder
will read resistance to ground in both directions.

ESS:: To
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.

To ensure an accurate resistance reading, do not touch
the resistor or leads during testing.
1.
Cut the output wire from the door lock switch/key cylinder in
half.
2.
Test with the meter from the switch side of the cut door lock
switch/key cylinder wire to a reliable ground source. Some good
ground references are the ground input source to the door lock
switch/key cylinder or the battery ground.
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.
