TROUBLE DIAGNOSES FOR SYMPTOMS
O/D OFF Indicator Lamp Does Not Come On
ECS004V2
SYMPTOM:
O/D OFF indicator lamp does not come on for about 2 seconds
when turning ignition switch to “ON”.
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 terminals 10, 19 and 28
●Refer to AT-350, "Wiring Diagram — AT — MAIN" .
●Ignition switch and fuse. Refer to PG-2, "POWER SUPPLY ROUTING" .
2. CHECK TCM GROUND CIRCUIT
1. Turn ignition switch to “OFF” position.
2. Disconnect TCM harness connector.
3. Check continuity between TCM terminals 25, 48 and ground.
If OK, check harness for short to ground and short to power.
OK or NG
OK >> GO TO 3.
NG >> Repair open circuit or short to ground or short to power
in harness or connectors. Refer to AT- 3 5 0 , "
Wiring Dia-
gram — AT — MAIN" .

TROUBLE DIAGNOSES FOR SYMPTOMS
Engine Cannot Be Started In “P” and “N” Position
ECS004V3
SYMPTOM:
●Engine cannot be started with selector lever in “P” or “N” position.
●Engine can be started with selector lever in “D”, “2”, “1” or “R” position.
1. CHECK PNP SWITCH CIRCUIT
With CONSULT-II
Does “TCM INPUT SIGNALS” in “DATA MONITOR” show damage to PNP switch circuit?
Without CONSULT-II
Does self-diagnosis show damage to PNP switch circuit?
Ye s o r N o
Yes >> Check PNP switch circuit. Refer to AT- 3 4 4 , "TCM Self-
diagnosis Does Not Activate" .
No >> GO TO 2.
2. CHECK PNP SWITCH INSPECTION
Check for short or open of PNP switch harness connector terminals 1 and 2.
Refer to AT-344, "
TCM Self-diagnosis Does Not Activate" .
OK or NG
OK >> GO TO 3.
NG >> Repair or replace PNP switch.
3. CHECK CONTROL CABLE
Check control cable. Refer to AT- 4 1 6 , "
Control Cable Adjustment" .
OK or NG
OK >> GO TO 4.
NG >> Adjust control cable. Refer to AT- 4 1 6 , "
Control Cable
Adjustment" .
4. CHECK STARTING SYSTEM
Check starting system. Refer to SC-20, "
STARTING SYSTEM" .
OK or NG
OK >>INSPECTION END
NG >> Repair or replace damaged parts.

TROUBLE DIAGNOSES FOR SYMPTOMS
A/T Does Not Perform Lock-up
ECS004VD
SYMPTOM:
A/T does not perform lock-up at the specified speed.
1. CHECK SELF-DIAGNOSTIC RESULTS
Does self-diagnosis show damage to A/T fluid temperature sensor, vehicle speed sensor·A/T (revolution sen-
sor), engine speed signal or torque converter clutch solenoid valve circuit after cruise test?
Ye s o r N o
Yes >> Check damaged circuit. Refer to AT- 3 8 1 , "TORQUE CONVERTER CLUTCH SOLENOID VALVE"
,AT- 3 8 6 , "BATT/FLUID TEMP SEN (A/T FLUID TEMP SENSOR CIRCUIT AND TCM POWER
SOURCE)" , AT- 3 5 3 , "VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)" , AT- 3 9 2 ,
"ENGINE SPEED SIGNAL" .— Except for Euro-OBD
No >> GO TO 2.
2. CHECK ACCELERATOR PEDAL POSITION (APP) SENSOR
Check accelerator pedal position (APP) sensor. Refer to AT- 3 6 2 ,
"ACCELE RATOR PEDAL POSITION (APP) SENSOR" (Except for
Euro-OBD).
OK or NG
OK >> GO TO 3.
NG >> Repair or replace accelerator pedal position (APP) sen-
sor.
3. DETECT MALFUNCTIONING ITEM
1. Remove control valve. Refer to AT- 4 1 3 , "
Installation" .
2. Check the following items:
–Torque converter clutch control valve
–Torque converter relief valve
–Pilot valve
–Pilot filter
3. Disassemble A/T.
4. Check torque converter.
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.
4. CHECK SYMPTOM
Check again.
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.
