does it have the skim options
the 1993 alarm is not SKIM like on 1999+
it has no skim so can not cut fuel like 1999 can.
but the ASD will drop for 7 other ways.
wow 1995 jeep but what jeep?, no model stated, really?
wrangler , Grand, Cherokee, or reg. Cherokee.?
USA car, not the EXPORT>?
that error is real. it says they can NOT Communicate.
the scan tool will not scan?
or did the scan tool scan then report other errors.
like PCM comm errors. or? is that the tool is dead.
or the PCM will not talk to you.
or is the PCM reporting that it can not comm. to other things?
please be clear. i cant guess what you really saw.
if the scan tool fails that means. (dead scans...?)
the 1995 is not obd2, it's obd1, so your tool is wrong tool.!!!
the 3160 is OBD2 only
and only works on all 1996+ cars and light trucks.in USA. ONLY.
the 3140 is the only tool for DIY, that works. 93-95 jeeps.
besides flash codes. (key on/off trick) do that yet?
no starts are mostly ASD relay drop outs. (and true in this case)
if the ASD drops while cranking, it is an ASD drop cause stall.
the ASD drops in about 3 seconds.
and is caused by up to 8 things,
all reported by the working scan too. (and sometimes the keyon/off trick works)
but not the skim reasons, listed, yours dont have SKIM.
are all fuses good?
wild guess on car . model next....
the book free , is it a ZJ jeep? or what, no matter its there...
if fuses are good
do the flash code way.
Start with the ignition off. Within five seconds, switch the key on, off, on, off, on. ("On" is NOT "Start" and "Off" is NOT "Lock").
The "check engine" light will flash. (codes)
Count the flashes. Each code is a two digit code,for example,23 would be FLASH FLASH (pause) FLASH FLASH FLASH (long pause). It may flash out up to 9 codes.
The best tool for 93 to 1995 is the INNOVA 3140
tool for OBD1 (with adapters) Bang for the buck, best.
key in mind at all times, turning off the key does clear some errors you never what to miss. like dead spark....
the method has value but is not good in all cases like real scan tool, that can show errors cranking or running.. or stalling.
