- Access Central Timer Module (CTM). CTM is located behind right kick panel. Disconnect CTM 18-pin connector "B". Using an external ohmmeter, measure resistance between ground and CTM 18-pin connector "B" terminal No. 10 (Black/Orange wire on Dakota or Light Green/Orange wire on Durango). If resistance is less than 1000 ohms, repair short to ground in Black/Orange wire on Dakota or Light Green/Orange wire on Durango. If resistance is 1000 ohms or more, replace CTM.
