Ok, went to check on some things on the LR3 and plugged the gap tool in, truck was in on position. Right after I plugged the tool in the hazards flashed, suspension lowered, F on dashboard, all kinds of errors. Truck won't start, turn key off, remove gap, truck starts but all the warnings there. What is that about as the last time I ran the tool, they did not exist and seems like gap and the lr3 are fighting. Had to disconnect battery and let it sit, then check engine was on, drove it some, came back, turned off, then on, check engine gone. Anyone seen this happen?
