Hi all,
I have a 1997 isuzu bighorn irmscher; 3.1 TD Automatic; 4JG2 engine.
My engine ECU came into contact with water via a flood. I immediately removed and serviced with quick Contact cleaner. After servicing it worked well, I then performed a manual diagnostic test and came up with the following codes 21, 31, 35 and 36. I then tried to clear the codes by disconnecting negative batter pole for 1 minute and then 24 hrs but This did not work. I then decided to trouble shoot codes 21 to see if it would go but i found notting to be wrong with accelerator sensor position all readng were found to be within range.
I believe that the water may have messed up the ECU.
I would like however to switch the engine ECU with that of a 1997 isuzu bighorn plaisiar 3.1 TD 4JG2 engine Automatic. MY major concern is that this ECU might require reprogramming and i unfortunately do not have access to the Tech 1 scan tool.
What should i do ?
