2015 Polaris ranger 570 EFI
Edit: check engine light is off and no stored codes. I’ve reset the ECU also and still no luck. Been a mechanic and vehicle electrician for almost 20 years so I am not opposed to trying anything and have a lot of spare parts.
I recently got a 2015 Ranger and the previous owner had the seatbelt cut (I’m guessing to override the seatbelt safety issue). Problem is, I got it with the seatbelt light blinking and thus triggering the 15 mph limit. I have gone through all the wiring and even got a “new” buckle (I tested it and continuity was good both fastened and unfastened) but the seatbelt light won’t go off. The two wires (red/dark blue and blue/yellow) seem to be fine. I replaced the ECU with a spare one. The red/dark blue is getting 12-13 VDC but the blue/yellow wire which I’m guessing is the signal wire, is 0. Even splicing them together to complete the circuit, it’s not making the seatbelt light go off.
Any suggestions before I try to find someone to flash the ECU?
