This is the Battery Troubleshooting Guide

I received my instrument cluster back after repair

My unit or instrument cluster still has erroneous diagnostic lights, unusual symptoms and/or not responding to certain tests or signal.

  • If the vehicle’s battery was not disconnected prior to removal of the unit, it may inadvertently blow a fuse along the wiring behind the dash, a relay near the fuse box, or a fuse in the one of the multiple fuse boxes in the vehicle.
  • Often times there are communication present if the unit is installed back in the vehicle. One of the fastest and easiest ways to clear any soft codes in the vehicle is to do a simply battery reset:
  1. Disconnect the battery cables
  2. Clamp the cables together with the terminals touching (off the battery!)
  3. Leave the cables maintained in this position for 15-20 and then re-install

*This should clear any soft codes and communication issues with the vehicle’s PCI bus.*
