- Locate Central Timer Module (CTM). CTM is located behind right kick panel. Disconnect CTM 18-pin connector "B". Using an external voltmeter, measure voltage between ground and CTM 18-pin connector "B" terminal No. 4 (Light Green wire on Dakota and Orange/Violet wire on Durango). If voltage is more than 1.5 volts, repair short to voltage in Light Green wire on Dakota and Orange/Violet wire on Durango between CTM and door lock switch. If voltage is 1.5 volts or less, replace CTM.
