ECD SYSTEM (w/o DPF) - DATA LIST / ACTIVE TEST
| DATA LIST |
- HINT:
- Using the intelligent tester to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
- NOTICE:
- In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

| Alternate Duty Ratio | Alternator generation duty ratio: Min.: 0%, Max.: 100% | No electrical load at idling: 10 to 60% High electrical load at idling: 100% | Duty value from ALT terminal | Battery deterioration Alternator malfunction Check for accessory lights, malfunctions, etc. |
| Results of real-vehicle check: Idling (No electrical load) (warm up the engine): 30% (2 minutes after starting the vehicle) | ||||
| Symptoms when out of range: - | ||||
| Diagnostic Note: Outputs the alternator generation duty in order to see the electrical load. Can be used to determine whether a higher-than-normal injection volume at idle, etc. is resulting from electrical loading or from some other source. For example, when the duty is not high but the idling injection volume is high, there is injector volume degradation or high engine friction. Can be used for judging whether or not a malfunctioning component in the electrical system is generating continual generation requests (ex. battery deterioration is causing an unending full recharge request, etc.). Regardless of whether or not an auxiliary device like the A/C or heater is active, the alternator duty is always at MAX status. There is an electrical system abnormality, like battery deterioration. | ||||

| Accel Position | Accelerator position status: Min.: 0%, Max.: 100% | Accelerator pedal released: 0% Accelerator pedal fully depressed: 100% | Accelerator pedal position sensor opening position ETC request opening position Cruise request opening position VSC request opening position | - |
| Results of real-vehicle check: Ignition switch ON: 0% (accelerator pedal released) Running without load (2500 rpm): 24.6% Running without load (4700 rpm): 99.6% (accelerator pedal fully depressed) | ||||
| Symptoms when out of range: - | ||||
| Diagnostic Note: "Accel Position" is the accelerator opening angle (%) for engine control use. When the MIL is illuminated, even with the accelerator pedal fully depressed and an "Accel Position" of around 10% or 25%, it means the fail-safe is restricting the accelerator. When the accelerator pedal position sensor output itself (Accel Sens. No.1 Volt % and Accel Sens. No.2 Volt %) is in the normal range, another actuator malfunction has caused the fail-safe to restrict the accelerator. Without cruise or ETC, VSC requests, and without accelerator restriction by the fail-safe, this is adjusted proportionally to the depressing of the accelerator pedal by the driver. Accelerator fully closed: 0% Accelerator fully open: 100% | ||||
- HINT:
- Accel Sens. No.1 Volt % and Accel Sens. No.2 Volt % express the value obtained by dividing the output voltage from the accelerator pedal position sensor by 5 (expressed in percentage). This is used only for diagnosing malfunctions in the accelerator pedal position sensor. Under normal conditions, it is sufficient to only check the accelerator opening angle final value "Accel Position".

| ||||
| Symptoms when out of range: Difficult to start, rough idling | ||||
| Diagnostic Note: The pre-glow ON period varies according to the engine coolant temperature. Whether the glow plug operation is affected or not can be determined by monitoring the glow plug energization command value when a problem occurs during engine start-up. When the battery voltage value remains the same even if the glow command is changed (ON to OFF, or OFF to ON), it is likely that there may be a malfunction in the glow plug or circuit. (TIPS: Whether the problem causes are related to the glow system or not can be determined only when all cylinders do not operate such as in a case of relay operation problem.) | ||||

| Symptoms when out of range: Difficult to start, rough idling | ||||
| Diagnostic Note: The after-glow ON period varies according to the engine coolant temperature. Whether the glow plug operation is affected or not can be determined by monitoring the glow plug energization command value when a problem occurs during engine start-up. When the battery voltage value remains the same even if the glow command is changed (ON to OFF, or OFF to ON), it is likely that there may be a malfunction in the glow plug or circuit. (TIPS: Whether the problem causes are related to the glow system or not can be determined only when all cylinders do not operate such as in a case of relay operation problem.) | ||||

| Symptoms when out of range: Difficult to start, poor driveability, lack of power, abnormal combustion noise | ||||
| Diagnostic Note: Fuel pressure is the actual common rail fuel pressure. Inspect by comparing the fuel pressure with the target fuel pressure. When in a stable condition such as when idling, the fuel pressure is within +/-5 MPa of the target fuel pressure. The ECM uses fuel pressure for feedback control of the target fuel pressure via the supply pump. The injection amount is determined based on the injection timing and fuel pressure. Also, the spray pattern is selected based on the fuel pressure. For startup, at least 25 MPa of fuel pressure is needed (take care as there is a response lag when the pressure rises). When the fuel pressure is below 25 MPa, it may cause rough idling. When the fuel pressure has decreased by 20 MPa from the target fuel pressure, there may be a lack of power. If actual fuel pressure is 40 MPa higher than the target fuel pressure, P1229 will be stored. When it is lower than the target fuel pressure, "Lack of Power" will occur, but a DTC will not be stored. When the fuel pressure is higher than 200 MPa, DTC P0088 will be stored. | ||||

| Diagnostic Note: ECU-calculated value for the suction control valve actuation target current. Value is large when a high fuel pressure is desired. Value becomes stuck at 3 A or more or operation is poor (poor movement due to deposits, etc.). When this deviates from the standard value, it indicates that for some reason, even though the pump is running hard, the actual fuel pressure is inconsistent with the target fuel pressure. | ||||

| Symptoms when out of range: - | ||||
| Diagnostic Note: Injection amount for each combustion. If injectors are clogged, fuel quality is poor, the fuel filter is clogged, or engine friction increases, "Injection Volume" will increase. If there is a malfunction due to low turbocharger pressure or a low intake air volume, the injection volume is limited and there is a lack of power. | ||||

| Symptoms when out of range: - | ||||
| Diagnostic Note: When the (actual) fuel pressure is equal to the target fuel pressure, this value becomes 0. This indicator can be used for diagnosing supply pump related malfunctions. When this value (absolute value) is large, it indicates that the difference between the actual and target fuel pressure is also large. A positive value indicates that the pressure feed is being increased due to insufficient pressure. A negative value indicates that pressure is being reduced due to excessive rail pressure. When the suction control valve does not close properly, it causes rail overpressure, and this value and the "Pump SCV Learning Value" slip to the negative volume side. | ||||

| Symptoms when out of range: Rough idling, black smoke, white smoke, poor driveability, lack of power, abnormal combustion noise, difficult to start | ||||
| Diagnostic Note: When idling after warm up, the injection amount for each cylinder is corrected to optimize the difference between the engine speed of each cylinder. Example: For cylinders that are slowing the engine speed compared to other cylinders, the injection volume is increased. "Injection Feedback Val" more than 3.0 mm3/st: Injector may have a problem which causes injection volume deviation, or insufficient compression which causes poor combustion may exist in the cylinder. If the value is within the correctable range which is controlled by the ECM and symptoms such as engine knocking and rough idling are not present, the system is normal even though the value exceeds 3.0 mm3/st, | ||||

- HINT:
- *: When cranking the engine, the Active Test measures the speed of each cylinder.
In this Active Test, the fuel of all cylinders is cut, and cranking occurs for approximately 10 seconds. At this time, the speed of each cylinder is measured. If the speed of one cylinder is higher than the other cylinders, the compression pressure of that cylinder is determined to be lower than the other cylinders.
Warm up the engine.
Turn the ignition switch off.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON and turn the tester on.
Enter the following menus: Powertrain / Engine / Active Test / Check the Cylinder Compression.
- HINT:

While the engine is not running, press the RIGHT or LEFT button to change Check the Cylinder Compression to ON.
- HINT:
- After performing the above procedure, the Active Test Check the Cylinder Compression will start. Fuel injection for all cylinders is prohibited, and the engine speed measurement of each cylinder will enter standby mode.
Crank the engine for about 10 seconds.
Monitor the engine speed (Engine Speed of Cyl #1 to #8, Av Engine Speed of All Cyl) displayed on the tester.
- HINT:
- At first, the tester's display will show the engine speed measurement of each cylinder to be extremely high. After approximately 10 seconds of engine cranking, the engine speed measurement of each cylinder will change to the actual engine speed.
- NOTICE:
After the Active Test Check the Cylinder Compression is turned on, it will automatically turn off after 255 seconds.
When the Check the Cylinder Compression test is off and the engine is cranked, the engine will start.
If the Check the Cylinder Compression test needs to be performed after it is turned on and performed once, press EXIT to return to the Active Test menu screen. Then perform the Check the Cylinder Compression test again.
