1998 sidekick sport auto - no key start - push button start
#23
keep in mind i have not seen the see your PRNDL hack
no country codes. on car, (vin or?)
all i know is what is in these text boxes, blind.

the car when new and PRNLD working (aka park lockout)
when you crank the engine the ECU sees that, and uses a special set of rules for cranking (start pin on PCM)
the PCM also knows where the shifter is selected.
if in park one idle profile is used
then when D,L,R is selected the TC clutch puts a huge load on the engine (stall speed RPM is 2000 rpm and hints at such a load with brakes on)
that PCM then uses special set of idle controls for all that, cold , and hot engine.
its not simple at all but fooling the PCM is always a bad idea, unless done perfectly.
this car PCM has 6 rangeswitch inputs from A/T PRNDL switch. and PCM A3 is the start pin , and 4wd pin so that OD is defeated in 4wd i think....
usually the scanning of the PCM will set range switch errors. got those yet? P1717 ( P1 are factory codes some scan tools cant read P1 errors) P17xx and P07xx are all transmission errors. x = wild card.


your USA 98 ECU p/n is 78E50 (E70 for calif) 97- 78ek0 (usa)
