TROUBLE DIAGNOSES FOR SYMPTOMS
1. O/D OFF Indicator Lamp Does Not Come On
ECS004V2
SYMPTOM:
O/D OFF indicator lamp does not come on for about 2 seconds
whenturningignitionswitchto“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 >> GOTO2
NG >> Check the following items:
lHarness for short or open between ignition switch and
TCM terminals 10, 19 and 28 (Main harness).
lRefer toAT-389, "Wiring Diagram—AT—MAIN".
lIgnition switch and fuse Refer toPG-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 >> GOTO3
NG >> Repair open circuit or short to ground or short to power
in harness or connectors. Refer toAT-389, "

DIAGNOSTIC PROCEDURE
1.CHECK PNP 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 “P/N”, “R”, “D”, “2” and “1” position switches moving selector lever to each position.
Check that the signal of the selector lever position is indicated
properly.
OK or NG
OK >> GOTO3
NG >> Check the following items:
lPNP switch (Refer to “Component Inspection”,AT-
387, "COMPONENT INSPECTION".)
lHarness for short or open between ignition switch and
PNP switch (Main harness)
lHarness for short or open between PNP switch and
TCM (Main harness)
lDiode (P, N positions)
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 >> GOTO4
NG >> Check the following items:
lPNP switch (Refer to “Component Inspection”,AT-
387, "COMPONENT INSPECTION".)
lHarness for short or open between ignition switch and
PNP switch (Main harness)
lHarness for short or open between PNP switch and TCM (Main harness)
lDiode (P, N positions)

4.CHECK OVERDRIVE CONTROL SWITCH CIRCUIT (WITHOUT CONSULT-II)
Without CONSULT-II
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Check voltage between TCM terminal 22 and ground when overdrive control switch is “ON” and “OFF”.
OK or NG
OK >> GOTO6
NG >> Check the following items:
lOverdrive control switch (Refer to “Component Inspection”,AT-387, "COMPONENT INSPEC-
