Can it be done without the scanner?

Someone said you can short 2 connectors to get them to clear

 

Why would you want to clear them with out fixing it? And the answer is no, they can't be cleared without the proper scanner or computer.

 

The code is a weak signal on back right wheel. Part is swapped but I need to clear it I believe and don't have a tool nor do I want to drive 100 miles to the dealership.

Thank you though, I'll see if anyone is willing to let me borrow the amigo.

 

weak signal on back wheel - you can get a screw driver on a Discovery I and pound on the sensor to move it a bit toward the toothed reluctance on the hub and the weak signal goes away.
Not sure if this works on Discovery II.

On Discovery I the sensor is just in via friction.

 

Still won't clear a 3 amigos set of lights, takes a scanner.
