Hi Peter,
Yes your are right about the termination for the last board which is D board. Never thought about that. It is true for even other serial communication like rs485

Thanks again for the advise. Will look for a good A board. But how do I know if it’s a good A board if I buy it from the junkyard?

You don't unless you know it comes from a working pack.

Hi Peter, I have swap the A board from another battery pack but still getting the check ima system error. A quick question, if a good battery pack is installed will the check ima system error goes away immediately or is there a procedure to follow to reset? Thanks

I have done the 12v battery reset by removing ground wire for 10 minutes and connecting back the ground wire. Still the same. Do I need take a long drive first to let it recalibrate or something?

I would expect it to reset itself and work normally. But you may have to wait till you get your HDS to do more trouble shooting.

We only have the info from your non HDS OBD tool at the moment, so that may be misleading us as to the board at fault.

Are you still getting the same trouble code? Have you checked?
Does the IMA work?

Didn’t have the chance to do the diagnose test yet.
Might go over to the workshop to test.
