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
“ENGINE” with CONSULT-II.
2. Start engine and maintain the following conditions for at least 10
minutes (Total). (It is not necessary to maintain continuously.)
CMPS·RPM (REF): 450 rpm or more
VHCL SPEED SE: 10 km/h (6 MPH) or more
THRTL POS SEN: More than 1.2V
Selector lever: D position (OD “ON”)
With GST
Follow the procedure “With CONSULT-II”.

Diagnostic ProcedureECS004R2
1.INSPECTION START
Do you have CONSULT-II?
Ye s o r N o
Ye s > > G O T O 2 .
No >> GO TO 3.
2.CHECK INPUT SIGNAL OF A/T FLUID TEMPERATURE SENSOR (WITH CONSULT-II )
With CONSULT-II
1. Start engine.
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Read out the value of “FLUID TEMP SE”.
OK or NG
OK >> GO TO 4.
NG >> GO TO 5.

3. CHECK INPUT SIGNAL OF A/T FLUID TEMPERATURE SENSOR (WITHOUT CONSULT-II)
Without CONSULT-II
1. Start engine.
2. Check voltage between TCM terminal 47 and ground while warming up A/T.
3. Turn ignition switch to “OFF” position.
4. Disconnect TCM harness connector.
5. Check continuity between terminal 42 and ground.
If OK, check harness for short to ground and short to power.
OK or NG
OK >> GO TO 4.
NG >> GO TO 5.
4. CHECK DTC
Perform Diagnostic Trouble Code (DTC) confirmation procedure. Refer to AT- 11 7 , "
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.
5. CHECK A/T FLUID TEMPERATURE SENSOR WITH TERMINAL CORD ASSEMBLY
1. Turn ignition switch to “OFF” position.
2. Disconnect terminal cord assembly connector in engine compartment.
3. Check resistance between terminals 6 and 7 when A/T is cold.
4. Reinstall any part removed.
OK or NG
OK (With CONSULT-II)>>GO TO 2.
OK (Without CONSULT-II)>>GO TO 3.
NG >> 1. Remove oil pan.
2. Check the following items:
–A/T fluid temperature sensor
Refer to AT-121, "
Component Inspection" .
–Harness of terminal cord assembly for short or open Voltage:
Cold [20°C (68°F)]→ Hot [80°C (176°F)]
