No, the ABS light will come on when there is a problem with the anti-lock braking system. Have this looked into by a professional. You will know your brake pads need changing when you hear a squealing sound when you apply the brakes.
The timing chain only needs to be repalced when it breaks. A light on the dash will come on once it's broken, and you can drive to the nearest Walmart and have it replaced.
you need to clear the code
There could be a number of reasons for that light to come on. My suggestion would be to have the vehicle checked over by a mechanic NOW. Good brakes are a number one priority!
You probably need to adjust the tension knob.
Speed sensor....on transmission need changing....
did you get air in the system maybe they need bleeding
generally a timing belt only needs replacing when it breaks
Your brake pads might need to be replaced.
It means your brake pads need changing.
If an check engine light does not come on it is a good thing. When your check engine light comes on, it means you need service done on your vehicle.
The traction light is on becasue there is no communication between the traction control and the ABS. You will need to check the ABS sensor which is probably damaged or need cleaning. The spanner light normally means go to workshop as there are some problems with the engine electric. The spanner light could be on because the traction light is on. Once the traction issue is sorted, the light should come on automatically. If the spanner light is on on its own or has been on before the traction light then probably the oxygen sensor needs changing.
Electronic Diesel Control {EDC} this light will usally come on if there's a problem in your fuel system. Try changing the fuel filter if this doesn't work you might need to get it plugged into a diagnostic machine to see if any fault codes are listed.
