How do you manually retrieve fault codes on a 1996 Jeep Cherokee?
There is a key ‘on-off’ sequence that you use. Turn the key to the ‘on position’ (last one before start), then off, and repeat two more times for a total of 3. On the last one, leave in the ‘on’ position and watch the ‘Check Engine’ light. It will go out after a few seconds, then begin a blinking sequence. Between the ‘ones’ and ‘tens’ numbers, it will pause. The light flashes so many times, then pauses, and flashes again. It will then pause between the next set of numbers. Example: flash-flash….flash-flash-flash means 2 and 3, for “23”. There is a pause between the last number and the next set, as I mentioned. The very last number will be “55”, meaning the diagnostic is through. The great thing about the 96 is that you can do the key sequence, but it’s still OBDII…and you can read them with a diagnostic scan tool. Auto parts stores sell them, but you can usually find a decent one at Harbor Freight for around $50-70 on sale. That’s really the only way to clear some codes.
