First off it could mean that you have a headlight that is burned out, or it could be that you need to tighten down your gas cap because the system has to have pressure to function smoothly. good luck. could mean lots of different things you can go too an auto zone store and they can run a free test
usually means to service your vehilcle soon
A problem has been detected . take your vehicle in for service , it could just be one of the sensors
If both lights are on the same vehicle then they mean 2 different things. Check Engine light means there is a problem with the emissions system. Service Vehicle means you need to perform regularly scheduled maintenance. Can mean you just need to change the oil/filter. Consult your owners manual for more information.
Most newer vehicles sense the miles and time since the last time the service light was reset. It's just a reminder to have the oil/filter changed.
Problem with emission system - have vehicle scanned to determine problem
The check engine light means there is a problem with the emission systems on the vehicle. The service engine light means that a regular schedule service is needed. Most of the time this means you need an oil/filter change.
That is the Service Engine Soon light. You need to have the vehicle checked at your earliest convenience.
It means that the engine computer has detected a malfunction that will affect the emissions of the vehicle.
re: bad regulator in the alternator WRONG ANSWER. these lights, when on at the same time, mean one that you will need to change one of your wheel bearings. You will need to have the vehicle scanned to determine which of the four is in need of replacement.
The ASR dash light is a brake assist system/acceleration slip regulation light. When this light comes on in the Isuzu NPR truck, the on board computer in the vehicle detected a malfunction in the acceleration slip regulation and the vehicle needs to be taken for service.
The on-board diagnostics have spotted a fault or the vehicle is overdue a periodic service.
it means that the car is due for service. a mechanic(certified) has the equipment to turn off the light. my car has run just fine for 60,000 miles with the light on
