DTC Confirmation Procedure

NOTE:
If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.




TESTING CONDITION:
Always perform the test at a temperature of -10°C (14°F) or higher. Engine coolant temperature and EGR temperature must be verified in "DATA MONITOR" mode with CONSULT before starting DTC WORK SUPPORT test. If it is out of range below, the test cannot be conducted.
COOLAN TEMPIS: -10 to 30°C (14 to 86°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 temperature or EGR temperature with a fan or means other than ambient air. Doing so may produce an inaccurate diagnostic result.
*: Although CONSULT screen displays "-10 to 40°C (14 to 104°F)" as a range of engine coolant temperature, ignore it.

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










4. Start engine and let it idle until "TESTING" on CONSULT 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 30°C (14 to 86°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°C to 30°C (14 to 86°F).




3. Check that voltage between ECM terminal 63 (EGR temperature sensor signal) and 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 DTC is detected, go to "Diagnostic Procedure".

No Tools
1. Turn ignition switch "ON".




2. Check the following voltages.
ECM terminal 59 (engine coolant temperature sensor signal) and ground:
3.2 - 4.4V
ECM terminal 63 (EGR temperature sensor signal) and ground:
Less than 4.8V
3. Start engine and let it idle for at least 60 seconds.
4. Turn ignition switch "OFF", wait at least 5 seconds and then turn "ON".
5. Perform "Diagnostic Test Mode II (Self-diagnostic results)" with ECM.
6. If NG, go to "Diagnostic Procedure".
When using GST, "DTC Confirmation Procedure" should be performed twice as much as when using CONSULT or ECM (Diagnostic Test Mode II) because GST cannot display MODE 7 (1st trip DTC) concerning this diagnosis. Therefore, using CONSULT or ECM (Diagnostic Test Mode II) is recommended.
