Door Disarm Switch Failure (Dakota)

Insert key into driver's door key cylinder and turn key between neutral, lock and unlock several times. Repeat for passenger's door lock cylinder and liftgate door lock cylinder. If binding or sticking condition exists at any door key cylinder, repair or replace door key cylinder as necessary. If all door lock cylinder's are okay, go to next step.
Turn ignition switch to OFF position. Disconnect driver's door key cylinder lock switch harness connector. Using DVOM, measure resistance between ground and door key cylinder switch connector Black/Light Green wire terminal. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, locate and repair open in Black/Light Green wire suspect wire. Perform BODY VERIFICATION TEST .
Disconnect passenger's door key cylinder lock switch harness connector. Measure resistance between ground and passenger's door key cylinder switch connector Black/Light Green wire terminal. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, locate and repair open in Black/Light Green wire. Perform BODY VERIFICATION TEST .
Gain access Central Timer Module (CTM). Turn ignition switch to OFF position. Disconnect CTM connector C2. Using DVOM, measure resistance between ground and CTM connector C2 terminal No. 10 (Light Green/Orange wire). If reading is less than 1000 ohms, repair short to ground in Light Green/Orange wire. If reading is 1000 ohms or more, replace CTM. Perform BODY VERIFICATION TEST .
With CTM harness connector C2, driver's and passenger's door key cylinder lock switch connectors disconnected, measure resistance of Light Green/Orange wire between CTM connector C2 terminal No. 10 and both door key cylinder harness connector. If both readings are less than 5 ohms, go to next step. If either reading is 5 ohms or more, locate and repair open in Light Green/Orange wire. Perform BODY VERIFICATION TEST .
Turn ignition switch to ON position. Measure voltage in Light Green/Orange wire. If reading is less than one volt, go to next step. If reading is one volt or more, repair short to ground in Light Green/Orange wire between CTM connector C2, driver's and passenger's door key lock cylinder switch connectors.
Turn ignition switch to OFF position. Connect CTM connector C2 connector. Turn ignition switch to ON position. Measure voltage in Light Green/Orange wire. If reading is 8-11 volts, go to next step. If reading is not 8-11 volts, replace CTM. Perform BODY VERIFICATION TEST .
NOTE: Two ignition switch keys are required for following test procedures.
Turn ignition switch to OFF position. Connect all previously disconnected components. Turn ignition switch to ON position. Using scan tool, monitor cylinder lock switch while turning driver's door lock cylinder switch from neutral to unlock positions. If reading changes from 2.5 volts in neutral position to one volt in unlocked position, go to next step. If reading does not change from about 3.4 volts in neutral to one volt in unlocked position, replace driver's door key cylinder lock switch. Perform BODY VERIFICATION TEST .
Monitor cylinder lock switch while turning passenger's door lock cylinder switch from neutral to unlock positions. If reading changes from about 3.4 volts in neutral position to one volt in unlocked position, go to next step. If reading does not change from about 3.4 volts in neutral to one volt in unlocked position, replace passenger's door key lock cylinder switch. Perform BODY VERIFICATION TEST .
Turn ignition switch to OFF position. Fault is not present at this time. Retest system. If fault remains, see appropriate procedure for symptoms present. See SYMPTOMS INDEX DIRECTORY table.
