DTC Confirmation Procedure
CAUTION:
Always drive vehicle at a safe speed.
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.
- P0400 will not be displayed at "SELF-DIAG RESULTS" mode with CONSULT-II even though DTC work support test result is "NG".
WITH CONSULT-II
- Turn ignition switch ON.
- Check "COOLAN TEMP/S" in "DATA MONITOR" mode with CONSULT-II.
Confirm COOLAN TEMP/S valve is within the range listed below.
COOLAN TEMP/S: Less than 40°C (104°F)
If the value is out of range, park the vehicle in a cool place and allow the engine temperature to stabilize. Do not attempt to lower the engine coolant temperature with a fan or means other than ambient air. Doing so may produce an inaccurate diagnostic result.
- Start engine and let it idle monitoring "COOLAN TEMP/S" value. When the "COOLAN TEMP/S" value reaches 70°C (158°F), immediately go to the next step.
- Select "EGR SYSTEM P0400" of "EGR SYSTEM" in "DTC WORK SUPPORT" mode with CONSULT-II.
- Touch "START".
- Accelerate vehicle to a speed of 40 km/h (25 MPH) once and then stop vehicle with engine running.
If "COMPLETED" appears on CONSULT-II screen, go to step 9.
If "COMPLETED" does not appear on CONSULT-II screen, go to the following step.
- Check the output voltage of "THRTL POS SEN" (at closed throttle position) and note it.
- When the following conditions are met, "TESTING" will be displayed on the CONSULT-II screen. Maintain the conditions until "TESTING" changes to "COMPLETED". (It will take approximately 60 seconds or more.)
If "TESTING" is not displayed after 5 minutes, retry from step 2 .
- Make sure that "OK" is displayed after touching "SELF-DIAG RESULTS". If "NG" is displayed, refer to "DIAGNOSTIC PROCEDURE ".
