Diagnostic ProcedureECS004UA
1.CHECK TCM POWER SOURCE
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Check voltage between TCM terminals 10, 19, 28 and ground.
3. Turn ignition switch to “OFF” position.
4. Check voltage between TCM terminal 28 and ground.
OK or NG
OK >> GO TO 2
NG >> Check the following items:
lHarness for short or open between ignition switch and
TCM (Main harness)
lIgnition switch and fuse
Refer to “PG-2, "
POWER SUPPLY ROUTING"”,
“POWER SUPPLY ROUTING”.
2.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 3
OK (Without CONSULT-II)>>GO TO 4
NG >> 1. Remove oil pan.
2. Check the following items:

3.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 5
NG >> Check the following item:
lHarness for short or open between TCM, ECM and
terminal cord assembly (Main harness)
lGround circuit for ECM
Refer to “”, “TROUBLE DIAGNOSIS FOR POWER
SUPPLY”.
4.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 resistance between terminal 42 and ground.
OK or NG
OK >> GO TO 5

SELF-DIAGNOSIS CODE CONFIRMATION PROCEDURE
After the repair, perform the following procedure to confirm the malfunction is eliminated.
With CONSULT-II
1. Start engine.
2. Select “SELF-DIAG RESULTS” mode for A/T with CONSULT-II.
3. Drive vehicle under the following conditions:
Selector lever in “D” position, vehicle speed higher than 10 km/h
(6 MPH), throttle opening greater than 1/8 of the full throttle
position and driving for more than 10 seconds.
Without CONSULT-II
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever in “D” position, vehicle speed higher than 10 km/h
(6 MPH), throttle opening greater than 1/8 of the full throttle
position and driving for more than 10 seconds.
3. Perform self-diagnosis.
