My ABS light has not worked for a long time so I bought a scanner to read the codes and find out why. In the ABS/SAS mode when checking the ABS side it says "No Communication." It works on the SAS mode and every other mode. Is the module bad, and is there a way to confirm this since I dont get a code for it? Thanks for any help.

 

most likely bad module. make sure the fuses are good and you can access the connector into the module and check it for power and ground. if the module has all the powers and all the grounds it should and no comm its dead

 

 

Thanks a lot. I will check these out.
