Grand Cherokee 4WD V8-5.2L VIN Y (1998)
If a malfunction is detected, a diagnostic trouble code is stored and will remain stored as long as the malfunction exists. When and if the
malfunction ceases to exist, an ignition cycle count will be initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of
that same malfunction, that diagnostic trouble code is erased and that ignition cycle counter is reset to zero.
If the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset and the diagnostic trouble code will continue
to be a stored code.
If a malfunction is not active while performing a diagnostic test procedure, the active code diagnostic test will not locate the source of the problem.
In this case, the stored code can indicate an area to inspect.
If no obvious problems are found, erase the stored code, and with the ignition "on", wiggle the wire harness and connectors, rotate the steering
wheel from stop to stop. Recheck for codes periodically as you work through the system. This procedure may uncover a malfunction that is
difficult to locate.
