DTC Confirmation Procedure

TESTING CONDITION: 

• Engine coolant temperature and EGR temperature must be verified in "DATA MONITOR" mode with CONSULT-II before starting DTC WORK SUPPORT test. If it is out of range below, the test cannot be conducted. 

  COOLAN TEMP/S: -10 to 40°C (14 to 104°F)* 

  EGR TEMP SEN: Less than 4.8V 

  If the values are out of the ranges indicated above, park the vehicle in a cool place and allow the engine temperature to stabilize. Do not attempt to reduce the engine coolant or EGR temperature with a fan or means other than ambient air. Doing so may produce an inaccurate diagnostic result. 

*: Although CONSULT-II screen displays "-10 to 40°C (14 to 104°F)" as a range of engine coolant temperature, ignore it.

WITH CONSULT-II 

1. Turn ignition switch OFF and wait at least 5 seconds, then turn ignition switch ON.
2. Select "EGR SYSTEM P1402" of "EGR SYSTEM" in "DTC WORK SUPPORT" mode with CONSULT-II.

4. Start engine and let it idle until "TESTING" on CONSULT-II screen is turned to "COMPLETED". (It will take 60 seconds or more.)

   If "TESTING" is not displayed after 5 minutes, turn ignition OFF and cool the engine coolant temperature to the range of - 10 to 40°C (14 to 104°F). Retry from step   1 .

5. Make sure that "OK" is displayed after touching "SELF-DIAG RESULTS". If "NG" is displayed, refer to "DIAGNOSTIC PROCEDURE ".

WITH GST 

1. Turn ignition switch ON and select MODE 1 with GST.
2. Check that engine coolant temperature is within the range of - 10 to 40°C (14 to 104°F).
3. Check that voltage between ECM terminal 63 (EGR temperature sensor signal) and engine ground is less than 4.8V.
4. Start engine and let it idle for at least 60 seconds.
5. Stop engine.
6. Perform from step  1 to  4.
7. Select MODE 3 with GST.
8. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE ".
