Proton Diagnostic Tools — PTSS/PTAS
Proton uses the PTSS (Proton Technical Service System) or PTAS diagnostic tool at authorised service centres. Generic OBD-II scanners read basic engine codes (P0XXX) but miss Proton-specific sub-codes for the 7DCT, AEB, and advanced safety systems on X50/X70/X90. For 7DCT clutch adaptation, transmission learning reset, or ADAS calibration after a windscreen replacement, only a PTSS-equipped Proton SC can perform the procedure correctly.
