I just finished replacing the rear struts on my 92 ls.Something done in that job,caused the anti lock/trac off light on the dash to come on.I cannott figure out how to turn it off.I disconnected the battry for a good while,that did not do it.I cannot find the answer in the service manuel.Please help; Michael.Carpe Diem.

 

Try pulling out the EFI or 'EFI Main' fuses for about 20 seconds and then re-insert. That resets the CPU, see if that works!
