1. PRODUCT APPLICATION INFORMATION
1.1 Outline
z The common rail system for the MZR-CD engine has been newly installed in the Mazda 5 and Mazda 6. The contents for the common
rail system are basically the same as those published in the previous Service Bulletin, "S/B Code: ECD02-06, Subject: New Common
Rail System (ECD-U2P) for Mazda." The two major points that have changed for this system are the addition of the DPF system, and
injectors equipped with the QR code. Please be sure to use this Service Manual together with the Service Bulletin as this edition ex-
plains only points that have changed.

3.3 SCV (Suction Control Valve)
z A linear solenoid type solenoid valve has been adopted. The length of time in which the ECU applies current to the SCV is controlled
(duty cycle control) in order to regulate the volume of suction of fuel into the pumping area. Because only the volume of fuel that is
required by the target rail pressure is drawn in, the drive load on the supply pump decreases, thus resulting in improved fuel economy.

(1) SCV Opening Small (Duty ON time long - Refer to the "Relationship Between Actuation

• When the opening of the SCV is small, the fuel suction area is kept small, which decreases the transferable fuel volume.

information for market service use
z QR codes have resulted in a substantial increase in the number of fuel injection quantity correction points, greatly imimproving pre-
cision. The characteristics of the engine cylinders have been further unified, contributing to improvements in combustion efficiency,
reductions in exhaust gas emissions and so on.

(1) Repair Procedure Changes (Reference)
• When replacing injectors with QR codes, or the engine ECU, it is necessary to record the ID codes in the ECU. (If the ID codes for
the installed injectors are not registered correctly, engine failure such as rough idling and noise will result). The ID codes will be reg-
istered in the ECU at a MAZDA dealer using approved MAZDA tools.

6.3 Operation of Sensors
z The Crankshaft Position Sensor (NE Sensor) as well as the Cylinder Recognition Sensor (TDC Sensor) have been changed to the MRE
(Magnetic Resistance Element) type. For the MRE type, when the pulsar passes the sensor, the magnetic resistance changes and the
voltage passing through the sensor changes. The change in voltage is amplified by the internal IC circuit and is output to the engine
ECU. In addition the Intake Air Pressure Sensor (MAPS) output characteristics have also changed.
(1) Crankshaft Position Sensor (NE Sensor)
• An NE pulsar is mounted on the crankshaft timing gear in order to output the signals that are used for detecting the crankshaft position.
The pulsar gear consists of 55 teeth and 5 missing tooth per pulse, thus enabling the sensor to output 55 pulses for every revolution
(360
°CA) of the crankshaft.

8. DIAGNOSTIC TROUBLE CODES (DTC)
8.1 About the Codes Shown in the Table
z The "SAE" diagnostic trouble code indicates the code that is output through the use of the STT (WDS). (SAE: Society of Automotive
Engineers)
8.2 Diagnostic Trouble Code Details
< NOTE >
*1 : In the event that the code "DTC0088" is displayed when using a diagnostic tool, there is a possibility that the injectors have exceeded the guarantee limit
(engine speed and fuel pressure parameters). Replace all injectors.
*2 : In the event that the code "DTC0089" is displayed when using a diagnostic tool, there is a possibility that the pressure limiter is open. Replace the rail.
*3 : In the event that the code "DTC1211" is displayed when using a diagnostic tool, there is a possibility of damage to one of the pump cylinders. However, if
the MIL lamp is on, verify that the vehicle is not out of gas. If there is even a small amount of residual fuel, refill the tank and check the MIL lamp again.
If the MIL lamp is still on, replace the pump.
*4 : In the event that the code "DTC1281" is displayed when using a diagnostic tool, there is a possibility that the pump has exceeded the guarantee limit
(engine speed and fuel pressure parameters). Replace the pump.
*5 : In the event that the code "DTC1329" is displayed when using a diagnostic tool, there is a possibility that the pump has exceeded the guarantee limit
(engine speed and fuel pressure parameters). Replace the pump.
