INSPECTION PROCEDURE

NOTICE:
Before proceeding to the diagnosis procedure, please carry out the below operations and check the cylinder.
1. Disconnect the injector connector of the cylinder number 2. Then turn the ignition switch to ON.
2. Check the DTC to see if P0202 is output.
3. If the output DTC is a different to P0202, follow the below instructions and carry out a diagnosis on the relevant cylinder.

HINT:
If the DTC is the same, conduct a diagnosis on that cylinder which the output DTC indicates.

Result:
If P0202 is output, repair cylinder number 3
If P0203 is output, repair cylinder number 4
If P0204 is output, repair cylinder number 2

NOTICE:
When replacing the ECM and/or fuel injector, the ECM needs Registration and Initialization (Click here).

HINT:
  1. When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the intelligent tester. Then after installing the new ECM, perform all of the initializations/registrations for the "Learning Values Write" function by following the instructions shown on the tester display.
  2. Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

1.INSPECT INJECTOR ASSEMBLY


    A200309E01

  1. Disconnect the injector assembly connector.

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    1 - 2
    		20°C
    		150 to 210 kΩ
