I have a Grand Limited 5.7 Hemi. It's done 110,000 Kms and I noticed that the right h and front turn signals stay permanently on whether the turn signal is activated or not. They also stay on when the car is locked and flatten the battery unless I disconnect it. I took it to the dealer and they gave me a 5 word report that "Open Short CCT on ECU" and told me it would cost $3,500 to replace it.
When I asked them for a more detailed explanation, they said that's as detailed as they could give me.
Does anyone else had this happen? In my knowledge of auto electronics (I repair military jets electronics) From what I can glean from the internet, the turn switch sends an earth to the ECU which probably switches a diode to send positive volts to each globe via the flasher can. So I can't see how this signal can be passed when the ignition is turned off.
The dealer replaced the turn, lights stalk 18 months ago because the headlights were coming on all the time, usually when I hit a bump or touched the stalk. I suggested this to them and they said that this fault has nothing to do with the stalk.
Any ideas from members?
