Renault traffic business - Stop start permanent fault - aroon

Can anybody assist with a fault on a 2020 renault traffic business.


Comes up check stop start, active fault, cannot be cleared.

Read codes with autel
DF083 STOP START MODULE CIRCUIT INCORRECT SIGNAL

Snap-on diag shows
DF0043 stop start configuration error.

Battery tested to be in good health and BMS on negative terminal shows around 1.6 volts varying.

I switched the battery and the BMS terminal with one of a different van and made no difference to the fault, still wouldn't clear. Autodata has no wiring diagrams for the vehicle so I don't know what voltages and resistances to expect from bms or alternator.

Any suggestions on diagnostics or where to look to confirm the fault?
