My ABS light stays on for a few minutes when the engine is first started on my Freightliner XC chassis . It then comes on and off speratically. Would a sensor cause this . If so how could I tell which one?
If your system is a Meritor Wabco there will be a button located somewhere near the dash or in an exterior compartment The ECU itself will be either a frame mounted or an interior mounted unit. There are many different blink codes. Most contain three digits mine has only two. The best way to find out is to locate the serial number which will be located on the face cover of the ECU and then contact Meritor. They have very good customer support. Once the unit is identified you will be able to download an operator’s manual. From there it is very straight forward. As an example my error code was 4-4 which tells you that the problem is with the driver’s side rear wheel sensor. That problem can be anything from a sensor all the way to the point that the wire harnesses connects to the ECU. The abs light should only come on when you first start the engine and then stay off.
