DTC CONFIRMATION PROCEDURE

CHECK DTC PRIORITY

If DTC P2263 is displayed with DTC P0237 or P0238, first perform the trouble diagnosis for DTC P0237 or P0238.

Is applicable DTC detected?

YES>>

Perform diagnosis of applicable. Refer to DTC Index.

NO>>

GO TO 2.

INSPECTION START

NOTE:

Use component function check to check the overall function of the turbocharger system circuit. During this check, a 1st trip DTC might not be confirmed.

Do you have CONSULT?

YES>>

GO TO 3.

NO>>

GO TO 4.

CHECK ELECTRIC WASTEGATE CONTROL ACTUATOR

With CONSULT

  1. Turn ignition switch ON and engine stopped.

  2. On the CONSULT screen, select “ENGINE”>>“ACTIVE TEST”>>“WASTEGATE ACTUATOR”.

  3. Operate “Up” or “Down”, set “W/G ACTUATOR POSITION B1” to 0.002 m, and make a quick short note of value “V1” of “W/G ACTUATOR POSI SEN B1”.

  4. Operate “Up” or “Down”, set “W/G ACTUATOR POSITION B1” to 0.015 m, and make a quick short note of value “V2” of “W/G ACTUATOR POSI SEN B1”.

Do the values of “V1” and “V2” change (visually, ACTUATOR SHAFT operates) and “V2” minus “V1” becomes equal to or more than 2.6 V?

YES-1>>

To check malfunction symptom before repair: Refer to Intermittent Incident.

YES-2>>

Confirmation after repair: INSPECTION END

NO>>

Proceed to DTC Diagnosis Procedure.

CHECK ELECTRIC WASTEGATE CONTROL ACTUATOR

Without CONSULT

  1. Turn ignition switch OFF.

  2. Disconnect Wastegate control actuator harness connector.

  3. While checking the POSITION SENSOR OUT voltage with an oscilloscope, apply a voltage of 12 V to the positive or negative terminal.

Does ACTUATOR SHAFT visually operate and POSITION SENSOR OUT voltage change?

YES-1>>

To check malfunction symptom before repair: Refer to Intermittent Incident.

YES-2>>

Confirmation after repair: INSPECTION END

NO>>

Proceed to DTC Diagnosis Procedure.
