2012 Volvo vnl670 D13, no throttle response.

I've seen misajusted brake switches cause weird things with the throttle with i-shifts. If the ecm thinks the brakes are applied, it may interfere with the throttle response. Usually its jerking and surging though.

 

Sorry for getting in your forum. I’m new to this website. I have a 2010 Volvo D13 engine 10 speed manual transmission. I have this code MID 144 PPID 74 FMI 4 I checked the vehicle Ecu and it says supply relay electrical fault. The trucks starts and turns off. Can anyone help thanks

 

Do you have the message on your dashboard that says “maintenance required vehicle Ecu”?

 

Ok
