bypass as in HACK?
old cars yes, but not newer.
by design. and law.
this IMMOblizer, (called by jeep. SKIM)
read the FSM book yet on 2002? chapter on SKIM.
chapter 8E, electronic modules.
page 21. read that page first . it answers why.
see secret key code and pin, good luck hacking that.
The skim module blocks the ASD relay (stalls engine)
scanning the PCM with any scan tool it will show, why.
SKIM key wrong, or ?
and with that error the ASD drops and the scan tool tells you that.
so, that means you need to make the SKIM happy.
hacking it , ill not cover, but good luck, its not easy and in most cases impossible.
and if you continue to hack away, the PCM sees that and bricks it self and other modules on the bus as punishments.
good luck hacking.
