disconnect battery for 15 mins...if it come back on there is a reason for the light being on...if so google vectra management light paperclip...hope this helps
Disconect battery for 10 mins , and its like brand new .
Not likely but it is possible.
My check engine light came on because the terminals were not connected tightly. no. quite the contrary. if you have a "check engine" light on, disconnecting, or in this case replacing the battery will turn it off. you have a different problem.
Disconnect the red terminal on battery and let it sit for 15-30 minutes, reconnect the battery and check engine light should be off because the computer has been reset.
The check engine light goes on because there is a problem with the engine control system. Until the problem is fixed it will continue to come back on even after you clear it by disconnecting the battery.
my engin management light comes on why
If your engine is running , and the battery light comes on , that indicates that your battery is not being charged
Alternator
When the engine light, electronic throttle light, and battery light all illuminate simultaneously in a Dodge Charger, it typically indicates a problem with the vehicle's electrical system or engine management. This could suggest issues such as a failing battery, alternator problems, or faults in the throttle control system. It's essential to diagnose the issue promptly using an OBD-II scanner or by consulting a professional mechanic to avoid further damage and ensure safe operation.
This the engine management system warning light.
