Dear Realin,

please state what Evaluation board you are using. Please state a full product number or a link to the evaluation board. If you have your own design please share the schematic with voltage levels and part values.

Dear Realin,

please make sure the BAT pin is unsupplied when you are trying to factory reset the UJA1169A. 

Please check and share the content of the WRCNTS bit in the MTPNV status register. To confirm that the SBC registers were not restored.

With Best Regards,

Jozef
