Ahc update issues (1 Viewer)

[Snooker]

Hello, I got new shocks for my 02 lx470. When changed out the mechanic started he couldn't get the suspension to leave the L setting.
It will not leave the L setting.
So I thought out was air in the system but when elevated all 4 wheels to bleed it the truck ahc went from low to normal height setting despite the wheels being fully extended.
It should be in high correct?
Am I wrong to conclude the height sensors got bumped or damaged and that's the reason it will not get out of L mode.
Also L mode blinks off but when elevated on the lift and the website was reading it was in normal mode but filet l fully extended the off light stopped blinking and turned itself off leaving the off light on.
Should I just get new height control sensors or how will I know if it is them?

Sounds like you need Techstream to figure out what's going on. The FSM will likely be helpful, too.

Techstream can help you as it will probably show some codes. You can go from there.

Out of curiosity, why did you replace the shocks (hydraulic rams)? These aren't really a wear item unless they rust or start gushing fluid.
