Re: Service, Diagnostic Troubleshooting and Repair, MUT 3

Yes, the unit can read error codes and clear them. It has also the "read data stream" function where I can see values from all the sensors in the car. About the stored information in car´s memory, at least I have seen data from the BMS like the actual Ah capacity of the battery. gisli, th...

Re: Extra battery connection

You Cannot connect the additional battery to the inverter as you are bypassing the main contactor which is located in the battery pack. Bad things will happen unless you have a way to connect the additional pack after the "ready" light is on and disconnect it before the "ready" ...

Re: Extra battery connection

Fantastic! Thank you gisli. Where did you end up connecting to the main battery? I got this far in pursuing the i909 unit, available for NA i-MiEVs, but haven't finished reading the fine print. No time now... http://www.icarsoft.com/web/icarsoftus/allproducts/mazdascantools/2012/201212/201212291225...

Re: Extra battery connection

Wow, that is great news. i'm glad you found a tool that would do the reset. does it also reveal any of the stored information from the car's memory, etc. over the can bus/diagnostic connector? Thanks for sharing, all info helps gain a better understanding... Yes, the unit can read error codes and c...

Re: Extra battery connection

GOOD NEWS! I managed to reset the error WITHOUT the help of the local dealer, thanks to this diagnostic tool : http://www.diagnostic-world.com/pages/mazda_code_readers_189127-z=563744&p=105904.cfm#content_item_105904 Now I don´t have to worry about producing more error codes as I can always rese...

Re: Extra battery connection

How long was the external battery connected after taking the car out of READY? The car will throw a code if the HV bus doesn't de-energize fast enough, which is exactly what would happen with an external battery connected. At the least, leaving the car sit for a while will clear the code, but at th...

Re: Extra battery connection

Have a look at this video link. This guy did something similar with his leaf. Similar problem. I think he blew the precharge resistor. Not sure if this is the case for your car but maybe it will give you some ideas. Don..... https://www.youtube.com/watch?v=6Zivzvh9Bx0&t=17s Thank you. Do you kn...

Re: Extra battery connection

I guess that when the car status changed from Ready to ACC mode the motor inverter still had the extra battery connected with 322 V, then the EV/ECU detected an error that creates the actual situation. I would guess that . . . . you're probably right - You did something the car didn't like, which w...

Extra battery connection

I am working on a project with I-Miev car, I have built 6 kWh removable battery to extend the range of the car. I connected the extra battery with 322 V direct to the motor inverter. The car at that moment was in "Ready mode" with car batteries exactly at 322 V. My plan was to charge the b...
