Multiplexed Door Lock Systems
Multiplexed door lock systems have more than one function on the same wire and require the use of dif-
ferent resistor values. It is necessary to use external relays any time a resistor is used.
Positive Trigger Multiplexed Door Lock System
Test Procedure for Multiplexed Door Lock Systems:
1. Locate the Lock/Unlock wire in the vehicle.
2. Cut the wire in half and determine the polarity of the wire.
3. Using a digital multimeter, measure the resistance for Lock and Unlock. (See Diagram)
