Re: Problemwith MCU P062F

If you look at the label on the MCU, there will be a part number and serial number. 9499A620 is a Mitsubishi part number for the MCU, and the C... number is the serial number. i suspect that those must also match in the eeprom in addition to the VIN; also if these are changed then the checksum will ...

Re: MiEV, potential regen braking issue

TCL is the traction controller system and no regen will occur with that error. Sometimes a low tire pressure or worn out tire such that the diameter is smaller than spec, will cause this error. The gear position sensor may have dirty contacts such that the B mode has intermittent contact; this could...

Re: Problemwith MCU P062F

Thank you for posting the contents of the eeprom.

What are the 2 bytes at the end of the line after the VIN--is that a checksum?

What is the part number of your MCU? Is it 9499A620 ?

What about the serial number, does it match the MCU in the car? CF1101004920 and 2 bytes for check sum?

Was this causing any (intermittent) faults?

Re: Problemwith MCU P062F

Which car make/model do you have miev, czero, Ion ?

How did you reflash the VIN into the MCU eeprom, using an external programming device or with the OEM tool?

Re: Not able to drive. P1A15 error.

And don't forget the connectors in the rear compartment at the MCU and OBC--these carry CAN buss signals also.

communication and OBC

If the big ceramic resistors have failed open, then no charging will occur and this will throw a DT Code. The code is stored in the EV-ECU, and it can only be retrieved by individuals and owners using aftermarket CAN buss tools such as an OBDII scantool or with a bluetooth or wifi dongle with one of...

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

The link did not show me the schematic, so i could not review it. Maybe you can post it as an image? It sounds like your test was good but the problem did not occur. Was there anything different--temperature, charge or change the 12V aux battery, etc? An intermittent problem is the most difficult to...
