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

. Just wondering how it gived 15% more soc? I've noticed our fuel meter jumping around when we disconnect the 12V. It's obviously affecting the calibration calculation rather than the actual state of charge. Do u think i might need ask maintenance just reprogram ECU to not get p1a15 active after ev...

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

Bonjour Christopher, I know if at least one case where clearing the error codes was not required, assuming the only error was from the charger. From what I've seen it seems some error codes are "self-clearing", but others aren't. If you double check everything, and can't find any fault, re...

Re: my Miev will not charge

Sounds promising Mike.

I'm again pondering which way the causal relation goes - did the wiring problem cause a fault elsewhere? Or is it a bit of a coincidence.

Imiev repair - precharge resistor

Does anyone know the specs for the pre-charge resistor in the imiev battery pack? In the process of diagnosing a failure to start (go into "ready") of our imiev, we believe we have isolated the issue to the pre-charge contactor and resistor. We are able to trigger the negative, main positi...

Re: my Miev will not charge

Fuel gauge is still displaying 4 bars. I think it is based on the BMS reading from the cell monitoring units, rather then from reading the overall pack voltage. It's definitely not taking a reading from outside the contractors. I should have noted what the fuel gauge did with the service plug removed.

Re: my Miev will not charge

This is the car that had the service plug removed. After replacing the service plug, the contactors chattered the first two attempts to start it, and haven't been heard from since. The i909 showed a stored trouble code for the service plug (P0A0A). The code isn't listed as active. I'm unable to clea...

Re: my Miev will not charge

REDCANE: If your fault is the fuses inside the battery pack, here is some info [...] Behind these plate covers are the fuses. I appreciate the information on getting to the fuses. It seems like the fuses are near the main connections to the pack (also need checking as part of the P1A15 diagnoses pr...

Re: iCarsoft i909 Diagnostic Tool

Further testing reveals I'm able to clear codes from other ECUs where they don't have an active code.

Re: my Miev will not charge

To me, it sounds like some other new fault has been introduced. [...] I think to go farther, you really need access to a MUT III, or get a dealer to run a scan on your car to see what the new fault actually is before you can go forward. My carsoft i909 (MUT alternative) turned up yesterday, and it ...

Re: iCarsoft i909 scan tool?

I got one on Monday. Reads trouble codes from EV-EVU, BMU, airbag etc.

However I can't get it to clear codes at this point :(
