Hi all,
my 1990 LS400 got check engine light on. with key in on position, I connect TE1 and E1 then get the following:
flash 5 times, a short pause, flash 6 times, a long pause then it keeps repeating over and over again the same patern (flash 5 times, a short pause, flash 6 times, a long pause)
i think ECU gives me error code 56 (!?) however, in the service manual, there isnt any error code number 56.
Also, i did try clearing the code by removing EFI fuse for a few minutes and put it back on, then driving the car for several km. re-read the ECU error code, got the same flashing patern described above
any help?
