I have an 03 Dodge Dakota that I have upgraded the overhead courtesy light to a trip computer removed from a 01 Dakota. It worked at time of removal. Everything works except for the temperature function which displays - - I have checked the wiring and sensor for temperature and they are operating properly. I have been unable to find out much about troubleshooting to find out why.
There is a scanner DRB-3 I believe can be used to program it. They are outdated and most dealers don’t have them anymore. I found a dealer that has one but says it is intermittent.
It costs$130 to “ flash it”. ??? Whether it works or not. If anyone has any information that would be helpful I would be grateful. Thanks

 

They are probably charging an hour labor.....

I have seen the DRB2 on ebay on occasion though. Might wanna see how much they are going for.

 

Just have to make sure you get the right cards. The gold card on it's own could have some value over the red/white cards. I paid 1K for my DRB2 with the computer interface and everything.

OP, I don't recall them requiring any configs. Was pretty sure it pulls the data off the databus organically, alongside fuel mileage data.

 

OP, do you have the long or short OHC? Because I have an 01 qc, and installed the trip from another and it didnt require any programming, all i had to do was reset it and do the learn procedure from the owners manual. Also when I purchased mine from the recycling yard, there are 2 variants of the long console, one is 7wire and one is 6wire based, depending on the bus.
