DTC Confirmation Procedure

CAUTION: Always drive vehicle at a sate 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.
- During the test, P0400 will not be stored in ECM even though "NG" is displayed on the CONSULT screen.

TESTING CONDITION:
Always perform the test at a temperature of -10°C (14°F) or higher.

With CONSULT
(1) Turn ignition switch "ON"
(2) Check "COOLAN TEMP/S" in "DATA MONITOR" mode with CONSULT.
Confirm COOLAN TEMP/S value is within the range listed below.
COOLANT 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.
(3) 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.
(4) Select "EGR SYSTEM P0400" of "EGR SYSTEM" in "DTC WORK SUPPORT" mode with CONSULT.
(5) Touch "START".
(6) Accelerate vehicle to a speed of 40 km/h (25 MPH) once and then stop vehicle.
If "COMPLETED" with "OK" appears on CONSULT screen, go to step 9.
If "COMPLETED" does not appear on CONSULT screen, go to the following step.
(7) Check the output voltage of "THRTL POS SEN" (at closed throttle position) and note it.
(8) When the following conditions are met, "TESTING" will be displayed on the CONSULT screen. Maintain the conditions until "TESTING" changes to "COMPLETED". (If will take approximately 50 seconds or more.)
CMPS.RPM (REF):
1,600 - 2,400 rpm (A/T models)
1,800 - 2,600 rpm (M/T models)
B/FUEL SCHDL: 3.0 - 4.5 ms
THRTL POS SEN:
X - (X + 0.(7) V (A/T models)
X - (X + 0.66) V (M/T models)
X = Voltage value measured at step 7
Selector lever: Suitable position
If "TESTING" is not displayed after 5 minutes, retry from step 2.
(9) Make sure that "OK" is displayed after touching "SELF-DIAG RESULTS". If "NG" is displayed, refer to "Diagnostic Procedure".
