Contact Mitsubishi direct as dealers like this give them a bad name. They can surely ship a replacement faster than that.

I vote with the other tech savvy here on the forum. The odds of the charger failing with the scenario you originally laid out are more than slim. The charger won't work if it doesn't "see" the Traction battery. The 12 volt boots up the system and pulls in the contactors which connect the Traction battery to the charger etc.

As Kiev said a 12V lead Acid can look OK on charging and standing voltage. But with a load added it craters almost instantly. Remove the load and it will pop back up to the voltage one would expect for a charged 12V.

Keep after them, make sure they diagnose the problem and give you a loaner car while they are waiting for the parts. I was just through a similar problem (warning light with the exclamation mark), and it took six months to get it sorted out. Details in this thread:

Guess what is wrong with my iMiev...

Wed Feb 03, 2016 10:55 pm

O.k. so now it has been almost two months that the iMiev is at the dealer's shop. I was swamped with work and also with a death in the family so I have not had time to follow up very much. But I called the service guy today; surprisingly he said that the charger arrived yesterday and they put it in and .... it did nothing. Just as someone on this forum said would happen. He said they had tested the 12V battery and it looks fine (I know this is different than getting a new battery and I told him this but he seems to think the 12V battery is o.k.). So now the are 'going back and forth' between the dealer and the service headquarters. I figure your educated and experienced guess is at least as good as the dealer's guess with a machine or two. So what do you think? bad cell in the main battery? bad 12V battery? bad connection in the wiring? Again, the car sat for a few weeks while I was out of town; the 12V battery was dead (but not the large one, which I charged prior to leaving); I trickle charged the 12V battery overnight and the car started right up. I drove it for a day with no problems, no lights. I plugged it in. It charged the main battery overnight. The next morning it would not start and gave the error light with a car and the exclamation point. It's sad not to have my iMiev!

My bet is still on the 12V battery being too weak. There are tests for a lead-acid battery to determine it's condition, e.g. electrolyte specific gravity measurement, voltage sag under heavy load, etc. Just charging it up and measuring the resting voltage is not a valid test.

But have them give you the list of codes that show up from the MUT and you can post them here, then we can see what the troubleshooting flowchart indicates and you can go back and ask questions. Just hooking up the MUT and clearing the codes is not a valid method to fix a car.

Geesh, I would tall them to just put a new one in, if it doesn't fix it then no one is out anything but 10 min.

I'll tell em again. The dealer seems to prefer to spends hundreds if not thousands of dollars chasing down ratholes.

I'm finally back after a long delay (on my part and on the dealer's). I tried calling the service guy I had been talking with regarding my iMiev and found out that he.... left the dealership for the Toyota service down the road. Fortunately they do seem to keep records of things and the new tech guy seemed to know at least what the issues were. I finally got a call from the tech supervisor, who seemed more informed and aware of things. Not sure why he didn't call me a month ago... They have been working on my car (on and off) for six weeks now. He said they changed the 12V battery early on and that did nothing. They also tested my 12V battery on another Miev and it started up that car fine. According to the tech manager they now have two levels of engineers at corporate Mitsubishi working on trying to diagnose the car. Apparently there is a 'Dave' at the national office who is the best guy they have at diagnosing these things. It has a P18A15 code (I think I heard that correctly), which, he said, was a pretty generic code so it doesn't pin-point a specific component that has failed. ??? -what?? I don't see anything on the web for this one that tells me much but maybe I'm looking in the wrong places. They also finally mentioned the traction battery today. The tech supervisor said that they cannot change it out yet because the error code does not point in that direction; because the corporate headquarters is footing the bill for the warranty work they have to have factory authorization to change components like that. So far they can't go there. I said it sounded to me like we were getting to a dead end. He didn't exactly disagree but said to wait and see what Dave comes up with. I'm waiting.

Howdy fresno,
Was the error code P1A15? If the result of Step 7 (reading the correct capacitor voltage) is Yes, then they replace the drive inverter (motor control unit); if No, then the solution is to replace the main battery pack, but there is plenty to check before reaching that point.

If i were troubleshooting without a MUT and out of warranty then i might measure the voltage with a handheld voltmeter. More later gotta head to the rink.

------------------------------------------------
DIAGNOSIS CODE SET CONDITIONS
If the charging time of the smooth condenser in the EMCU reaches the specified time or more, the diagnosis code No. P1A15 will be set.

PROBABLE CAUSES

Thanks very much for all of that info. I'll see what I can get out of the dealer...
Kenny, I PM'd you; I'd like to talk to you directly so that I can talk more intelligently to the dealer. Hopefully we can shorten the learning curve for the dealer.... (even though it is supposed to be a iMiev capable dealership).
