Got the original charger back on the car before I change CMU09 back to the repaired one Nice to report that the black box elements fire up and the car is charging again from this unit - so it was the CMU09 fault that was scotching the whole elements originally as I hoped. Pleased as it shows I...

Went to the Grampian Transport museum whilst on holiday last week and was rather surprised to be met at the entrance by a silver 12 plate Imiev on display with a couple of other electric cars as part of their display. Go 400 miles plus north in a 76 year old car to be met by an imiev in a...

no because it worked on the original charger to the car - one which needed a black box and was quite happy working from the house charger - this current one is from the red CMU car with the straight 13amp plug - works beautifully only on the charge cable which came with the donor car. Came to...

Repaired CMU board due back today and will then be able to test it and see if its fixed - will mean the battery pack gets dropped a fourth time but... Been thinking about the charger situation - currently got the early standard UK 13amp type plug no black box type charger on the car which works...

More Have now sent off the damaged BMS board to be hopefully be repaired. Been out in the car tonight - forgotten how delightful it is to drive and nice to have less range worry knowing that the powerpack is much better than before. Still no DTC issues and even the battery flash on when key...

my black box charger has code 9499xxx but my early charger dated 2015 has 9481 code assume I have to live with the situation and not use the house charger or change the OBC back to the the original 2011 one and see if this actually works then keep the 2010 early one as a spare. This is now...

Success - I have a working car again. Put the battery pack back in properly but have left off the plastic shroud as plan to get the CMU09 green board repaired with new LTC chip and see if that solves the issue and stupidly I left out the plastic air flow thing over the front pack so have to be...

Yes that is right - we had this issue at the start of this thread since everyone told me it had to have a certain length of numbers and my working car conforms and is fine but the donor car has a short version and the conclusion was it may have been an early batch of imports? my working car is...

These are the two boards fitted together. The red one from 2010 car with a funny short vin the green from 2011 car. Have had movement from car on drive with this one red board fitted to green pack but can only move inch each way as pack not attached to car doing that job now Only issue is that...

Further news With much thanks to Mickey particularly who never seems to say no to try this and so got braver today Have had the pack up and down from the car more times than I care to remember with much frustration and annoyance as more and more things did not fix. Have tried as per video...

Not been sat completely still today - finished editing this about the BMS investigations I have done so not all waste. Hope it helps but here is proof that moving the CMU pcbs away from their designated positions does not confuse the car but you can only have one ID of each within the pack so...

Is this chip easy to change once I have one? Used to do some PCB work with schools etching my own etc but never dealt with commercial pcb repair will check temperatures on the OBD drive app

no damage or corrosion visible all looks like new. The gold contacts were fine and did run a fibre cleaner over the battery terminals where they connect to the pcb but these same batteries gave no error when connected to the adjacent pack with cmu10 board. Looking at the voltages on hobdive All...

Started on car today Put to DRIVE and moved an inch each way. Instantly cm09 fault comes back into dtc codes. Now does not go away. However cells are still registered on the battery meter but once the cm09 fault is registered on the system the battery dash board meter goes blank even if it...

car goes into drive no issues and still not DTC raised on hobdrive cannot drive as battery pack separate to the car - best not to even get the car to start to move I think incase especially as the pack and car are 6ft up in the air Cells all look pretty stable and decent too not planning to...

hv leads connected but not dared turn to drive. Shall l? What potential damage could I do.

Decided against disturbing the cell packs which were not giving me grief. As cmu09 and cmu10 were loose anyway swapped these over so the cmu were transposed cmu09 board was in cmu10 place. Reconnected as per Mickey instructions and got to first key on ignition to find that all battery cells on...

So have dropped battery pack which is getting easy having done three drops in past 6 weeks! Removed cmu 09 block and measured cells compared to what hobdrive read out said. Hobdrive was little variable with cells DEF being slower to get to the whole pack voltage Measured all voltages with...

no swap cells and keep the CMU in the same place that way if I get a CMU fault in the new position we know it is the cells but if we get a CMU fault in the same place then we can suspect the board is faulty. You said that you cannot swap the CMU around

Even with the older style non brick type obc was not sure if the early obc was house charge 16amp compatible? Not got another modern electric might ask friend ... So I need the obc to work to solve cmu issue possibly and chademo will not do this for me Will try this try to find it This is a...
