A Volvo dealer can't fix it ? It's probably needs volvo software to read the codes and give them some idea of were to start. Hill Start Assistant and Antilock Brakes and probably Traction Control System.

Remember when it was the drivers job to start on a hill, control the wheel lock up and the driver was the traction control?
If these safety systems can make trucks almost idiot proof, these same systems are important steps to achieving autonomous?Last edited: Feb 26, 2021

Hey Nas. The gentleman stated that "nobody" can fix this issue. I think between both of us we are fixing 5-6 a month.

MichaelK1 Where are you located? Bring it to the shop where I work and I will fix it.
I'm in Northwest Canada.black_dog106 Thanks this. -
Most likely an ABS problem. Both Traction Control and Hill Start Assist requires ABS to work.
flood Thanks this. -
Definitely an ABS related problem could be a failed TC solenoid or wiring too.
