Its a SAS equipped Toyota counter balance so it must be switched ON when your jacking it!
Jack up the front & support the truck on suitable blocks.
Lift the forks Up & use a suitable mast prop to support the fork carriage / mast ( depending on mast spec )
There is a black pressed steel cover that protects the underside of the traction motors & hides the sensors - unbolt & remove this cover to gain access to the 4 x sensor.
