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.

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.
