1. O/D OFF Indicator Lamp Does Not Come On=NJAT0331SYMPTOM:
O/D OFF indicator lamp does not come on for about 2 seconds
when turning ignition switch to ªONº.
1 CHECK TCM POWER SOURCE
1. Turn ignition switch to ªONº position.
(Do not start engine.)
2. Check voltage between TCM terminals 10, 19, 28 and ground.
Voltage: Battery voltage
SAT467J
3. Turn ignition switch to ªOFFº position.
4. Check voltage between TCM terminal 28 and ground.
Voltage: Battery voltage
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
(Main harness).
+Refer to ªWiring Diagram Ð AT Ð MAINº, AT-123.
+Ignition switch and fuse Refer to EL-10, ªPOWER SUPPLY ROUTINGº.

2 CHECK TCM GROUND CIRCUIT
1. Turn ignition switch to ªOFFº position.
2. Disconnect TCM harness connector.
3. Check continuity between TCM terminals 25, 48 and ground.
SAT468J
Continuity should exist.
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 ªWiring Diagram Ð AT Ð MAINº, AT-123.
3 CHECK LAMP CIRCUIT
1. Turn ignition switch to ªOFFº position.
2. Check resistance between TCM terminals 13 and 10.
Resistance: 50 - 100W
SAT469JB
3. Reinstall any part removed.
OK or NG
OK©GO TO 4.
NG©Check the following items:
+O/D OFF indicator lamp.
Refer to EL-144, ªMETERS AND GAUGESº.
+Harness and fuse for short or open between ignition switch and O/D OFF indicator
lamp (Main harness)
Refer to EL-10, ªPOWER SUPPLY ROUTINGº.
+Harness for short or open between O/D OFF indicator lamp and TCM.
