O/D OFF Indicator Lamp Does Not Come OnECS00EBE
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. (Do not start engine.)
2. Check voltage between TCM connector terminals 10, 19, 28 and ground.
3. Turn ignition switch to OFF.
4. Check voltage between TCM connector 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 connector terminals 10, 19 and 28

Refer to AT- 3 9 5 , "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.
2. Disconnect TCM connector.
3. Check continuity between TCM connector 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 9 5 , "
Wiring Dia-
gram — AT — MAIN" .
3. CHECK COMBINATION METERS SYSTEM
Check combination meters system. Refer to DI-14, "
Combination Meter" .
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.

VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)

6. CHECK HARNESS BETWEEN TCM AND REVOLUTION SENSOR (POWER)
1. Turn ignition switch OFF.
2. Disconnect the TCM connector and revolution sensor harness connector.
3. Check continuity between TCM connector and revolution sensor
harness connector. Refer to AT- 2 1 , "
Circuit Diagram" and AT-
395, "Wiring Diagram — AT — MAIN" .
4. If OK, check harness for short to ground and short power.
5. Reinstall any part removed.
OK or NG
OK >> Fuse or ignition switch are malfunctioning.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
7. CHECK HARNESS BETWEEN TCM AND REVOLUTION SENSOR (SENSOR GROUND)
1. Turn ignition switch OFF.
2. Disconnect the TCM connector and revolution sensor harness connector.
3. Check continuity between TCM connector and revolution sensor
harness connector.
4. If OK, check harness for short to ground and short power.
5. Reinstall any part removed.
OK or NG
OK >> GO TO 5.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
8. CHECK DTC
Perform AT- 3 3 2 , "

TROUBLE DIAGNOSIS

TROUBLE DIAGNOSISPFP:00004
Trouble Diagnosis IntroductionEHS000CL
CAUTION:

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harness can be identified by yellow and/or orange harnesses or har-
ness connector.

Do not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.

Keep ground portion clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-II.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system mal-
function through the operation of the “AIR BAG” warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the “AIR BAG” warning lamp and CONSULT-II are as follows:
NOTE:
Seat belt pre-tensioner malfunction is indicated by “AIR BAG” warning lamp.
HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.
