DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE
CAUTION:
●Always drive vehicle at a safe speed.
●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 mal-
function is eliminated.
With CONSULT-II
1. Turn ignition switch “ON” and select “DATA MONITOR” mode for
“A/T” with CONSULT-II.
2. Drive vehicle and check for an increase of “VHCL/S SE·MTR”
value increase.
If the check result is NG, go to AT- 1 2 5 , "
Diagnostic Procedure" .
If the check result is OK, go to following step.
3. Select “DATA MONITOR” mode for “ENGINE” with CONSULT-II.
4. Start engine and maintain the following conditions for at least 5
consecutive seconds.
VHCL SPEED SE: 30 km/h (19 MPH) or more
THRTL POS SEN: More than 1.2V
Selector lever: D position (OD “ON”)
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 AT- 1 2 5 , "
Diagnostic Procedure" .
If the check result is OK, go to following step.
5. Maintain the following conditions for at least 5 consecutive sec-
onds.
CMPS·RPM (REF): 3,500 rpm or more
THRTL POS SEN: More than 1.2V
Selector lever: D position (OD “ON”)
Driving location: Driving the vehicle uphill (increased
engine load) will help maintain the driving conditions
required for this test.
