ABS Malfunction Code

[jrichards64]

As I discussed in a earlier thread, my 2000 Disco II has the dreaded 3-amigos issue. Joey was kind enough to recommend cleaning the ABS sensors, which I am in the process of completing. I remembered I had the codes pulled a couple of weeks ago, and the code relevant to this issue is as follows:

P1590 - ABS Road Signal Circuit Malfunction.

The error code description from the RAVE CD-ROM Manual states the following:

P1590 - ABS Road Signal Circuit Malfunction. Hardware is OK, but SLABS ECU is sending an error signal

Does this mean I won't have to buy any new hardware to fix the problem? Will simply cleaning the ABS sensors clear the 3-amigos error? And, once I clean the ABS sensors, will I have to have a shop clear the 3-amigos, or will they clear automatically once I clean them (assuming they are the problem)?

And, the passenger side rotor is stuck and will not budge. Any suggestions on how to remove the frozen rotor so I can get to the ABS sensor?

Thanks again for your help!

IIRC you should be able to get to the sensor without removing the rotor. Just unscrew the nut/part that holds the sensor, then remove/clean sensor. I could be wrong on this.

ABS codes will clear themselves.
