On a recent trip I ran over a ladder that had fallen out of a truck. The ladder cut the wire to the passenger side rear. Mechanic says the senser was replaced with a factory replacement. He does not know what to do, suggest taking to a Mercedes dealer. First problem is there is no dealer that will work on a Sprinter MH in my area. Second problem is that my daughter also has a Sprinter chassis MH and it also has the dash light issue after a recent replacement of a chassis fuse.
Any ideas?
 
First check that the ABS fuse, under the drivers seat or in the footwell, is good. A blown fuse will keep the light on. Be advised meantime, AI says a malfunctioning ABS on a heavy sprinter chassis is a significant safety risk.
 
From experience I have found the ABS sensors are "sensitive" It's possible the "ladder incident" affected another sensor. I suggest raising up the front, removing the sensor heads, clean with a cloth, replace and push in all the way. Do this on all four. You may have to drive the MH a few miles for a reset, but if it's your sensors, this should fix it. Good luck, Blessings

With systems now a days you can’t just replace a sensor. You will have to reset the system. I’d take it somewhere and have a scanner check for any stored malfunctions caused by the broken sensor. Some readers are able to reset the codes to see if they reset.

Also you may have to disconnect the battery for 1 minute. This resets memory in some areas.
