EFI Frontier problem (Kohler EFI)

[jtb51b]

Just tried 5 and 6 cycles with no luck. My display works, other than temperature. it has never worked and I was lead to believe they do not work on air cooled units. The oil pressure light illuminates until you start the engine, the (i) will illuminate if the parking brake is on. The light between them, has no indication of what it is and it never lights. The Check engine light also never illuminates. Was I told correctly about the temp not being activated on the air cooled units?

I've never had an issue with one yet, here is a manual which states MIL may not have been installed by mfr. . I do not see one in the Argo manual wiring, no there would be no temp. reading as Argo uses the water jacket in the Aegis. I'll look at our 8x8 later today.

OK, am I reading correctly that you do NOT see the wire in the harness of this machine for a MIL? That would definately explain it! It makes no sense that argo would leave that very important function out. My owners manual doesnt even have my unit listed in the specs pages. Has water cooled EFI kohlers, and kohlers with carbs listed but no air cooled 747 efi. Maybe I got the wrong book? Maybe mine was so new that they didnt provide the correct book yet. Who knows, and I guess it doesnt much matter but its curious.

Sorry I forgot this last time, went to Gil's and our 8x8 Frontier with the 23 the MIL light doesn't light either, perhaps because there is no self diagnostic feature of the Comand efi's like the Aegis engines. Again I personally have no complaints with what we have out there so I never looked into it.

Your cluster is adjustable to remove the temp function icon from it like all previous air cooled engines. Understand the cluster fits all models so there are functions not applicable to all models included in it.

Traced the wiring using a Kohler manual. The MIL wiring IS intact and runs to the LCD. I have checked the system with a test light and it functions as it should, the MIL wire is the ground for the light. No codes present, which is good but I still need to figure out why the LCD is not lighting the MIL. I am going to take the LCD unit apart and see if there is something inside thats an easy fix. If not, I will add an MIL lamp to the dash somewhere, I will not buy another LCD just for that one function.. FYI the MIL wire in the argo harness is a green wire with a white tracer all the way from the engine to the LCD.

Thank you, i didnt see this until after my last post. Thought I refreshed but no. I have no idea why they would have the system wired in all the way from end to end and it not be setup to work. There has to be some good reason for that? MIL lamps are invaluable in troubleshooting EFI engines! And yes these DO have a self diagnostic mode, I just used it.

Thanks again, I will post back what I find inside the LCD unit.

Call your Argo dealer and ask them to e mail a copy of service bulletin SB229. This likely addresses your check engine light not functioning.

Done and Done. Already installed the kit. Works like a champ now.

Thanks!
