DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION
PROCEDURE
NCAT0220S03
CAUTION:
I
Always drive vehicle at a safe speed.
I
Be careful not to rev engine into the red zone on the
tachometer.
NOTE:
If “DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCE-
DURE” has been previously conducted, always turn ignition
switch “OFF” and wait at least 5 seconds before conducting
the next test.
After the repair, perform the following procedure to confirm the
malfunction is eliminated.
With CONSULT-II
1)
Turn ignition switch “ON” and select “DATA MONITOR” mode
for “ENGINE” with CONSULT-II.
2)
Start engine and maintain the following conditions for at least
5 consecutive seconds.
VHCL SPEED SE: 10 km/h (6 MPH) or more
THRTL POS SEN: More than 1.3V
Selector lever: D position
ENG SPEED: 450 rpm or more
Driving location: Driving the vehicle uphill (increased
engine load) will help maintain the driving conditions
required for this test.
If the check result is NG, go to “Diagnostic Procedure”, AT-61.
With GST
Follow the procedure “With CONSULT-II”.
