I did the test procedure per Midwest ABS to check the ohms between the ABS connector and the wheel sensors.. all sensors should ohm between 900-1380. My wheel sensors all showed good except the right rear..
- LF- 1129 ohms
- RF- 1155 ohms
- LR- 1123 ohms
- RR- 0 ( I guess bad sensor or wire problem ? )
phils94850 » I decided to open up my ABS module and re-solder the joints. As you can see in the bottom pic below with the pump motor plug unhooked im getting about 9 volts, but.. when I plug the pump motor plug back in and probe the wire going to the motor im getting nothing.
I used jumper wires from the battery and ran 12v constant to one side of the pump motor plug and a ground from the battery to the other side of the plug and the pump motor comes on. That’s why I think the module must ground the other wire to make the pump run when it needs to..
My question is.. should I get constant voltage thru the plug to the pump or does it stay zero volts until the module activates it by grounding the other wire ? Trying to figure out if I have a bad plug or what ??
