Now all you
have to do is reverse the steps to reinstall your computer.
Additional
Instructions
1996-1997
PCM’s do not have any other special procedures, other than idle
relearn. Start, and allow to idle in Park until engine is at normal
operating temperature if desired.
1998-2000+
PCM’s require an antitheft ‘relearn’ procedure as follows:
(1). Attempt to
start vehicle. You MUST rotate the ignition key enough to try to
start the vehicle. Vehicle will briefly start and quit. LEAVE KEY
ON—this is NORMAL.
(2). Observe
“Security Light”. The Security light may initially flash, but will
remain on steady for a period of 10 minutes, provided you left the
key in the ON position. When the security light goes out (10 minutes
have expired), turn the key OFF—and wait 5 seconds.
(3). Repeat steps
(1) through (2) EXACTLY AS STATED an additional 2 more times for a
total of 3 relearn attempts. Remember to turn the key off
between each of the 3 total relearn attempts as stated in step (2).
(4). Truck should
start on the 4th attempt, provided you didn’t make a
mistake in one of the 3 prior relearn sequences. This is a simple
procedure, but often done incorrectly.
(5). If there’s
no “Check Engine” illuminated, everything is fine. If the “Check
Engine” lamp is on, there may be one additional step which requires
the use of a scan tool, to enable the PCM to know where the
crankshaft sensor is in relation to camshaft. It is totally safe to
drive your vehicle to any repair centre to have this service
performed (a 2-3 minute procedure. 90% of the time, this does not
need to be done). All diagnostics are performed normally with this
performance computer.
