1998 Plymouth Grand Voyager SE 6 cyl, 3.3L. Check engine light on, speedometer/odometer not working after changing battery
1998 Plymouth Grand Voyager SE 6 cyl, 3.3L. Installed new battery - fired up the car - check enging light came on, speedometer & odemeter stopped working. Prior to changing the battery the car ran like a champ! No OBD Codes. Dealer says they checked all the electrical and can't find anything. Dealer says to replace the PCM and hopefully that will fix it. I'm not willing to spend $1105.00 for "hopefully". Is there a PCM fuse or relay of some type that would keep it from communicating? Any ideas? Thanks in advance for your ideas!
I would return the battery while still under warranty and install a different one. It could be a faulty battery.
