Re: 12v battery keeps draining - parasitic drain?

headlight relays, tail light relays, any relays associated with the Brakes, the ABS, the ACS and the EV-ECU. These are all on fusible links without a tiny fuse in the box. Also the keyless entry/immobilizer is not clearly defined that i can find in the manual. Good luck i know it's tough to chase th...

Re: 12v battery keeps draining - parasitic drain?

It seems like a stuck relay, maybe the contacts have welded together and its not able to open and shut off the circuit. Pull the relays one by one to find the culprit. e.g. the windows can be rolled up within about 20 seconds after you turn off the key due to a timer circuit that keeps power for tha...

Re: 12v battery keeps draining - parasitic drain?

That is definitely too high, it will draw about 5AHr in one day and our little aux battery is only good for about 20-35, so it will flatten it in a hurry. Usually everything has a fuse or a fusible link. Are there any aftermarket equipment installed, e.g. radio, camera, heater? Maybe someone added a...

Re: It looks like I just got an Anderson modified i-MiEV

What is under the charging door on the passenger side? Does it not have the regular AC charging port? Maybe you need to look under the lid in the trunk to see if it has an On-board Chargger, or has been modified with an aftermarket chargger? If you can find the OEM OBC, it is now under warranty from...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

Like Coulomb stated there is likely a much bigger issue. The capacitor was just a symptom of a failure, not the cause. The 5V power supply is suspect and many chips are powered by that buss. There is also a 16V supply and the 12V input voltage lines. There is a fuse on the board that hopefully blew ...

Voltage Monitoring Chip

IC509 is an MB3793 Power Voltage Monitoring ic from Fujitsu. "A reset signal is output when the power is cut or falls abruptly. When the power recovers normally after resetting, a power-on reset signal is output to microprocessor units (MPUs). An internal watchdog timer with two inputs for syst...

Re: No READY. P1A15 error. Condenser charge timeout.

Where is the chip location that holds the VIN info in the MCU / invertor ? It is U6 located nearby to the ISA board. See page 2 of this thread for a picture of the main board in the bottom plenum. Did you get my PM from last year, it had my home email address if you have questions or need help. Bas...

Re: not charging my iON, cell or CMU or BMU problems

It wasn't clear to me that there was a defective LTC chip, maybe so, but there were 2 very low cells, #38 and #42. So after swapping out a CMU05 board, the low cell #38 is not reading low anymore? Was the cell voltage actually measured with a voltmeter to verify it's actual reading before and after ...

Re: Mitsubishi/Citroen OBC trouble

Hi again Kiev. Now I have replaced the MCU Fuse and soldered on a replacement for the snubber cap that was cracked. Result: The yellow fault symbol in the dashboard is gone, but i still have a fault code 0006 on my diagnose tool i don't know where or how you are reading these codes, but OBC code 6 ...
