Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome! My name is ***** ***** I can assist you with your question. Please start by sending me your VIN. Also, please feel free to accept my offer and call me.
Thank you for that information. This problem is caused by a bad instrument cluster or a bad front control module
You would have to do some diagnostics.. Check each circuit individually. A scanner would be best to use for these tests..
I bet there are codes in the computer that is not working. Again, a scanner will help because it can pull codes from both the front control module and the instrument cluster.
You could even try to disconnect the battery cables from the battery for about 10 minutes to see if that does the trick. Sometimes the module will simply lock up and need to be reset.
Which modules have codes in them? What are the code numbers?
Are you saying that one of the modules would not even communicat at all?
Ok, then check all powers and grounds at the cluster. If they check out good, the cluster is bad and will need to be replaced.
Pins 1 and 14 on the C1 connector are B+ voltage, on the C3 connector pins 13, 24, 25 and 26 will B+ voltage with the key on. Next check the grounds on C1 pin 13 and C3 pins 11 and 12.
A wiring diagram or a pinout chart?
Here is connector 1
Here is connector 3
