I have a 1995 Isuzu Trooper and am getting the diagnostic code Flash... Flash,Flash. I believe thet means 12. Does that mean solenoid circuit failure? And if so, what do I need to do to fix my rig?
When you flash codes on a 95 trooper..it should flash code 12 pause and flash code 12 two more times...if no other codes flash it means there are no codes stored...code 12 is basically, enter codes, beginning of codes and end of codes.
I just double checked cos 95 models were I thought allrunning the obd 2systems..but production dates after the 8th month are considered next year models..so maybe yours is a late year production. I am going to send a picture and pre odb2 code 12 is a code..hope this helps!

2000 trooper wont start!!! pulled it in the driveway shut it off then wen't to leave and wouldn't start. i changed the starter relay and still nothing. makes a clicking noise and that is it. is there a...
Sounds like the starter solenoid is working, but the starter motor isn't. If you have a voltmeter or test light, measure for light/12 volts at the motor terminal while someone tries the key. If the solenoid is what is 'clicking', but nothing at the motor terminal, change the solenoid. If you get light/12 volts, then the motor itself is in trouble.

4x4 light is flashing (TOD indicator)
this means there is a problem if it continuosly flashes
Short-circuit terminal 8 of the self-diagnostic
connector to GND to display the trouble code on the
CHECK lamp.
If no trouble codes exist, code “12” is displayed continuously.
If trouble codes exist, code “12” is displayed three times, and then other trouble codes, starting from the smaller code number, these are displayed three times respectively.

this is located behind right front centre console side trim..
