• The on-board diagnostic system is essentially carried over from that of the current MPV (LW) MZR-CD (RF
Turbo) engine models, except for the following. (See MPV Workshop Manual Supplement 1737-1*-02C.)
— DTCs, PID monitoring items, and simulation items have been changed.
— KOEO/KOER self-test items have been changed.
