sorry for being late
Ok. This is voltage measurement
Disconnect J1 from ZFE.
pin 1/3/29 in connector plug at the red line of your voltage meter, black to battery ground > battery voltage min 12,6V
pin 5 black line and red to battery positiv > same result > 12,6V
pin 26 red line and black to ground cycle ignition on > same result> 12,6 V
pin 17 can-h, pin 16 can-l >>maybe this connections failed. To measure these cables/connections you have to disconnect
all ECU's from the wiring. Then!! Resistance measurement!
after disconnect the battery!
pin 17 to BMS-K pin 53
pin 16 to BMS-K pin 52
pin 17 to ABS pin 30
pin 16 to ABS pin 15
here you have to read 0 Ohm Ω, otherwise check the cables for chafe marks.
Important points > wire straps
I think you need a wiring diagram. Please be careful, that's a professional job.
