VY Climate control DIAGNOSTIC MODE

[KillerCV8]

Hi There,

Seems quite a few posts on how to get VT/VX climate control into Diagnostic mode,

Does anyone know how to get the VY climate into diagnostic mode ?

If so does anyone know what the codes are and if the ambient air temp. sensor can be calibrated ?

Sozz. I only know of being able to test/adjust via TECH2
