Need help with warning lights
 

My 2003 H2 just started flashing the security light, battery light and the fuel low light as well as the fuel gauge going off then back on when all lights go out. This is crazy and was wondering if anyone has had this problem? It does this about every 5 minutes or so. ?????

I figured it out, all is good now. Seems no one ever had this problem

you might post what you did to fix it. Might help someone else later

Glad to hear that you fixed it. What was wrong?

Warning Lights
 

I have a remote start that works when you double click the key fob. My daughter likes to get in my truck and press the door locks twice which starts the truck. When i came out of the house I just put the key in and switched to run position and drove away. My pass lock thought I had stole the truck I guess and kept trying to shut the engine down. I did not realize what was going on till I remembered that my kid had started the truck from inside not using the key fob . This is why the computer was thinking it was stolen. I got home and removed the battery cables, put my key in the door lock, hooked the battery back up and locked and unlocked the door which reset the pass lock. All was good after doing that, no more warning lights.
