I have a KM c652DS with a C3B02. We have replaced the fusing unit, IHPU, PRCB and REDB and coil unit. Checked the operation of the upper right door. All checks good. Any suggestions?:mad:

looks like you have changed everything that the service manual want's, the only thing that i can think of is cabling that runs between it.
also after changing all the boards did you firmware update it ?.

this is my first fault of the day today, coincidentally.

Stupid question, but did you do a trouble reset ? fusing/critical errors must be reset in this manner

interestingly, I reset it and it worked for about 10 minutes and returned.

I've got a new coil and ihpu on its way for first thing tomorrow, hope this doesn't turn into a pain in the ass too.
