I have installed a 2002 drive by cable LM7 into my Toyota Land Cruiser. Been driving it for a month or so. It's been great. All but the evap monitor had passed and I passed the emissions test for state emission. Anyway this evening I came out from the restaurant I had parked at after grabbing my take out and went to start the engine. It would not idle. I pulled up my obd2 scanner I had on me and noticed all the monitors were now not complete. I was in the restaurant for about 15 minutes. My first thought is to pull the blue and red ecu plugs and make sure all the female pins look like they're fully clipped into the plug. Any other Ideas? It's like I disconnected the battery but I didn't. And the clock on my dash isn't flashing 12:00 or anything which would indicate a loss of vehicle power.

 

There are only 2 orange wires that are constant hots, usually they are fused. I would check the fuses and the 2 wires.
