Dodge Caravan Repair Question
Dodge Caravan non working gauges and turn signals!
I took a peek at the wiring diagram and it seems there is an "Intelligent Power Module" located on the left side of the engine compt. This may be an issue. some questions ...... what prompted you to change the BCM? Was it new or used? did you do any testing on the mutifuntion switch on the column? Is your scan tool capable of interfacing with the BCM (ie:bidirectional? meaning you can command the BCM to do certain output controls) for outputs? Let me know and we'll go from there!
Hi! I replaced the BCM in hopesthat that was the problem. It is a used one, and didn't cost squat. I got lucky! Just got back from a Dodge Dealership, and this is what is says on the paper they gave me:
CK for codes 9 codes in BCM/ tried to relearn
Run test found no communication from cluster
Need further Diag/ need to pull out instrument
cluster and CK power/ possible cluster failure
Guess I should start looking at the instrument cluster huh!?
Sounds like a plan. Let us know
Just put in an instrument cluster. No change at all, will I need to have the dealership reprogram to see if this works now, where I had changed the BCM before? I am running out of ideas and time!
Ouch, was afraid of that. time to go deeper! Ummm .... 1. do you have a multimeter? (or at least a test light?) would strongly recommend the basics first. powers and grounds! Let me know if you need a diagram and/or procedures!
Thank you Chris! Where the heck should I start testing?? I do have the Chilton book.
Start by looking at the wiring diagram for the bcm and i/p, locate the power and ground wires and test each one. Let me know if you need a more detailed diagram!
I would appreciate detailed wiring scymatics, and your thoughts on trouble shooting procedures. Today, we went through fuses and relay box. Checked for corosion on wiring harnesses, appear to be in good shape, and wrapped.
Email w/ diagram and instructions in your inbox!
Thank you Chris!
