Thanks for the info! I tried it, but I can’t seem to get any blinking codes. I flipped the kill switch three times (both fast and slow), but the FI light never flashed. I also bridged the service connector under the seat, and the dash just showed “CHK” without any blink sequence, or error codes.
Could you clarify how exactly it should be done? Do I need to wait until the dash finishes its startup and shows the CHK message before flicking the kill switch, or should I be doing it during the “startup” while there is nothing on the dash?
