Here are a few things that could possibly be the issue:
-
This is most likely a faulty harness plug, bad connection, or fuse issue. Make sure the pins are not pushed back on the plug and the pins on the cluster aren’t bent.
-
Clean both sides with an electrical cleaner.
-
Make sure there is no bad grounding.
- Perform a hard battery reset. Instructions and video are below:
Hard Battery Reset
-
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 one of the multiple fuse boxes in the vehicle..
-
Often times there are communication issues 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 simple battery reset:
- Disconnect the battery cables
- Clamp the cables together with the terminals touching (off the battery!)
- Leave the cables maintained in this position for 30mins. and then re-install.
HELPFUL TIP
Whenever doing a hard reset (global reset) always remove the ground cable first then the positive cable. When reinstalling a battery or just the cables install positive first then attach the ground. It's always best to do it this way so there are almost no issues causing an electrical spark on a module in the vehicle.
