A/T 4speed fails, car wont move until hot.
many parts on this PCB can not be bought today.

the idle switch is GOOD.
but the ECU is bad.
my duty page lists over 18 ways for the regulation of idle to fail. lots of ways.
but if you had a scan tool?
and it was connected.?
you'd see communications going dead. as car ran. (this is the ECU CRASHING)
just like that deal with 12s failing, that too is crude form of communications (human to ecu)

ISC is last , to work on all Suzuki's these year.
dead last.
and is because we are ignoring all other bad signs. code 12s and the stalling.

if the ECU does not like the diagnostic jumper, that means it got ISSUES.
the ECU does jobs (tasks) on priorities. (how ever crudely) If the ecu crashes (caps bad) the ecu reboots and sees thin rpm very high (its running still (coasting to stop possible) its first job is to get spark online, then fueling, back
and the Diag pin is on the last end of list to work. and can skip this.

the Diag mode failing tells me the ECU is overtaxed, (crashing tops list)
we have seen 12s even skip mid stride. 1/2 flashed out. and doing that over and over...

we should not even bother with the ISC, on this sick ECU,
idle controls are the last thing to calibrate... dead last. and we must not try.
not now.

time to start a new post
my 16v ECU is acting up. code 12s, fail, code 12s, on demand cause engine to stall. Diag mode FAILS.

bad caps
and with gross damage from leaking caps, due to acid spill inside ecu. as is common.

your doing great.
got new tranny
new steering.
now we can fix the ECU..... everyone does this 1989 to 1995
i had a brand new, ecu (nos, new old stock) not long ago, in hand, a 1992, and the caps were all good.(tested)
this ecu sat in and air conditioned warehouse for (20+ years)
it had rubycons on it, and were the first ones I ever saw to be still good this old. (id still replace then with nichicons)
