1997 Infiniti QX4.
The ABS lamp has been on for a few months and using the ABS flash lamp trouble diagnostic method I got the error codes #'s 21, 22, and 26. That was great but I have no idea what to do next as the maintenance manual does not show how to perform the repair(s). Code 21 was the 1st and then the other two in the order listed. Reading the footnotes in the manual I noticed that codes 22 and 26 could be caused by one or more wheels spinning on a slippery road which did happen about 3 weeks ago after a freezing storm.
It would be greatly appreciated if anyone can share some light on the subject.
Thank you.
