CONTROL SYSTEM OUTLINE [AJ] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513)

BME014000000T52

• The control system for Mazda MPV has been adopted or changed the following parts.
- BARO sensor for barometric pressure detection has been adopted. (European (L.H.D.) specs.)
- EGR boost sensor for EGR monitor and barometric pressure detection has been adopted. (Australian, General (L.H.D. R.H.D.) specs.)
- Rear HO2S (RH, LH) has been adopted. (European (L.H.D.) specs.)
- The intake manifold communication control (IMCC) system has been adopted to increase the engine torque.
- Electric distribution ignition function of electric spark advance (ESA) system has been changed.
- Electric fan control has been changed.
- Controller area network (CAN) for communication with TCM has been adopted.
- ECT signal output function has been adopted for system simplification.
• The shape and the construction of the parts in the control system have been changed due to the adoption of the AJ engine.
