Hi: My 2006 Durango SLT four wheel drive will not start. I traced the problem to the can B curcuit. The can B - is reading 13 volts to ground and the can B + is reading 0 volts to ground. If I am correct these should be about 2.5 volts each to ground. I have checked each module on the circuit seperately (Can B isolated) and got these values.
Sentry key module Can B - 12.9volts Can B + 0 volts
A/C heater module Can B - .1 volt Can B + .1 volt
Occupant Restaint module Can B - 0 volts Can B + 0 volts
Radio Can B - 12.9 volts Can B + 0 volts
Cluster Can B - 5.3 volts Can B + 0 volts
Occuant Classification Module Can B - 12.9 volts Can B + 0 volts
Front Control module Can B - 12.9 volts Can B + 0 volts

Can someone please tell me if my check is wrong or do I have major issues with several modules?
