POWER SOURCE)
Diagnostic Procedure
ECS007PS
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:
●Harness for short or open between ignition switch and
TCM
●Ignition switch and fuse
Refer to EL-11, "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)>>GOTO4
NG >> 1. Remove oil pan refer to AT-406, "
REMOVAL"
2. Check the following items:

OK or NG
OK >> GO TO 2
NG >> Repair open circuit or short to ground or short to power
in harness or connectors.
2.CHECK LAMP CIRCUIT
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Disconnect A/T device harness connector.
3. Check voltage between A/T device terminals 8 and ground.
OK or NG
OK >> GO TO 3
NG >> Check the following items:
●Harness for short or open between combination
meter terminals 47 and A/T device terminals 8.
3.CHECK OVERDRIVE CONTROL SWITCH

2.CHECK PNP SWITCH CIRCUIT (WITHOUT CONSULT-II)
Without CONSULT-II
1. Turn ignition switch to “ON” position. (Do not start engine.)
2. Check voltage between TCM terminals 26, 27, 34, 35, 36 and
ground while moving selector lever through each position.
OK or NG
OK >> GO TO 4
NG >> Check the following items:
●PNP switch (Refer to AT- 2 4 2 , "COMPONENT
INSPECTION" .)
●Harness for short or open between ignition switch and
PNP switch
●Harness for short or open between PNP switch and TCM
●Diode (P, N positions)
3.CHECK OVERDRIVE CONTROL SWITCH CIRCUIT (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 “OVERDRIVE SWITCH”.
Check the signal of the overdrive control switch is indicated properly.
(Overdrive control switch “ON” displayed on CONSULT-II means
overdrive “OFF”.)
OK or NG
OK >> GO TO 5
NG >> Check the following items:
●Overdrive control switch (Refer to AT- 2 4 2 , "COMPO-

HOW TO ERASE SELF-DIAGNOSTIC RESULTS (WITHOUT CONSULT-II)
1. If the ignition switch stays “ON” after repair work, be sure to turn ignition switch “OFF” once. Wait for at
least 3 seconds and then turn it “ON” again.
2. Perform “SELF-DIAGNOSTIC PROCEDURE (Without CONSULT-II)”. Refer to AT- 2 5 0
.
3. Turn ignition switch “OFF”. (The self-diagnostic results will be erased.)
