DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
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. Check the following.
If the check result is NG, go toAT- 1 8 3 , "
Diagnostic Procedure" .
If the check result is OK, go to following step.
3. Turn ignition switch “ON” and select “DATA MONITOR” mode for
“ENGINE” with CONSULT-II.
4. Start engine and maintain the following conditions for at least 3
consecutive seconds. Then release accelerator pedal com-
pletely.
VHCL SPEED SE: 10 km/h (6 MPH) or more
THRTL POS SEN: Approximately 3V or less
Selector lever: D position (OD “ON”)
If the check result is NG, go to AT- 1 8 3 , "
Diagnostic Procedure" .
If the check result is OK, go to following step.
5. Maintain the following conditions for at least 3 consecutive sec-
onds. Then release accelerator pedal completely.
VHCL SPEED SE: 10 km/h (6 MPH) or more
Accelerator pedal: Wide open throttle
Selector lever: D position (OD “ON”)
With GST
Follow the procedure “With CONSULT-II”.

Diagnostic ProcedureECS004S8
1.CHECK DTC WITH ECM
Perform diagnostic test mode II (self-diagnostic results) for engine control.
Refer to EC-58, "
Malfunction Indicator (MI)" (QR25DE) or EC-790, "Malfunction Indicator (MI)" (QR20DE).
OK or NG
OK (With CONSULT-II)>>GO TO 2.
OK (Without CONSULT-II)>>GO TO 3.
NG >> Check throttle position sensor circuit for engine control.
2.CHECK INPUT SIGNAL (WITH CONSULT-II)
With CONSULT-II
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Read out the value of “THRTL POS SEN”.
OK or NG
OK >> GO TO 4.
NG >> Check harness for short or open between ECM and
TCM regarding throttle position sensor circuit.

3. CHECK INPUT SIGNAL (WITHOUT CONSULT-II)
Without CONSULT-II
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Check voltage between TCM terminals 41 and 42 while accelerator pedal is depressed slowly.
(Voltage rises gradually in response to throttle position)
OK or NG
OK >> GO TO 4.
NG >> Check harness for short or open between ECM and
TCM regarding throttle position sensor circuit.
4. CHECK DTC
Perform Diagnostic Trouble Code (DTC) confirmation procedure. Refer to AT- 1 8 1 , "
DIAGNOSTIC TROUBLE
CODE (DTC) CONFIRMATION PROCEDURE" .
OK or NG
OK >>INSPECTION END
NG >> 1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector. Voltage:
Fully-closed throttle valve: Approximately 0.5V
Fully-open throttle valve: Approximately 4V
