The ABS Light is on when I start my car. This has been going on for quite a while. The mechanic mentioned that there may be problem with the wheel sensor or the computer disc at the engine compartment. Any fast solution?
If your mechanic has the time, you can ask them to check at the ABS Wheel Speed Sensor. It is located within the Brake Rotor 'hat' and as you can imagine, will take some time and work to take out.
Most of the time, it just needs cleaning but be careful, as the plastic casing may be brittle.
This will just be Labor costs to you, but if you can do it yourself, hey, all the better!
In any case, if it doesn't work, then as Tech said, look at the ABS Modulator.
Where are you in Malaysia? Since you are from Malaysia, try to check with the mechanic and try get a rebuild one. A rebuilt version should cost less than RM500 only. If you were quoted more, then they are trying to make a quick buck.
Also to add to that if they have the computer to read the codes then they should be able to spin the tire and read the signal.
When the modules go bad there will still be a signal but the computer will say a permanent fault with the right rear sensor.
