2006 Chevrolet Express 3500 My Security light comes on (dash light) if the car is turned off keys out.
My Security light comes on (dash light) if the car is turned off keys out.
What is your question?
If I leave the van (actually an RV) off the security light will come on and stay on and drain the battery. I bought this vehicle used and it has had some modifications done by the coach builder at the factory and then by the previous owner. It has a keyless entry that appears to be aftermarket and I can not find it to disconnect. It has a trailer brake system and an aftermarket radio. The dome light did not come on when the door was opened and recently I disconnected the battery and after reconnecting it the light works again. The car shows no diagnostic codes and runs great. If I put the key in and advance to run position it gets rid of the security light. Could it be a bad bcm causing this?
