Mazda CX-90 OBD-II / MDS Diagnostic Malaysia

CX-90 PHEV requires Mazda MDS (latest version) for full diagnosis — standard generic OBD readers can read basic codes but CANNOT access PHEV HV system, battery SOH, inverter, or electric motor data. PHEV fault codes have separate DTC tables from ICE codes. Battery management system diagnostics: dealer only. Malaysia: ensure your workshop has current MDS software before any PHEV service.
