INSPECTION PROCEDURE 3
The engine warning lamp does not illuminate right after
the ignition switch is turned to the ON position.
Probable cause
Because there is a burnt-out bulb, the engine-ECU <M/T> or engine-A/T-ECU <A/T>
causes the engine warning lamp to illuminate for five seconds immediately after the
ignition switch is turned to ON. If theengine warning lamp does not illuminate immediately
after the ignition switch is turned to ON, one of the malfunctions listed at right has
probably occurred.
D
Burnt-out bulb
D
Defective warning lamp circuit
D
Malfunction
of
the
engine-ECU
<M/T>
or
engine-A/T-ECU <A/T>
OK
Check the trouble symptom.
NG
Check the harness wire between combination meter and engine-
ECU <M/T> or engine-A/T-ECU <A/T>, and repair if necessary.
OK
Check the following connectors:
B-02, B-32, B-36 <M/T>, B-95 <A/T>
NG
Repair
NG
Check the engine warning lamp power supply circuit, and repair
if necessary.
OK
Measure at the combination meter connector B-02.
D
Disconnect the connector, and measure at the harness side.
D
Voltage between 53 and earth (Ignition switch: ON)
OK:
System voltage
NG
Check a burnt-out bulb.
NG
Replace
NG
Replace the engine-ECU <M/T> or engine-A/T-ECU <A/T>.
OK
Check the trouble symptom.
OK
Check the following
connector:
B-36 <M/T>,
B-95 <A/T>
NG
Repair
OK
Measure at the engine-ECU connector B-36 <M/T> or the
engine-A/T-ECU connector B-95 <A/T>.
D
Disconnect the connector, and measure at the harness side.
D
Earth the terminal No. 36 <M/T> or No. 22 <A/T>.
OK:
The engine warning lamp illuminates.

Data list
16 engine-ECU power supply voltage (Refer to P.13A-154.)
NG
Check the engine-ECU <M/T> or engine-A/T-ECU <A/T> power
supply and earth circuit.
(Refer to P.13A-147, INSPECTION PROCEDURE 25.)
INSPECTION PROCEDURE 4
The engine warning lamp remains illuminating and never
goes out.
Probable cause
In cases such as the above, the cause is probably that the engine-ECU <M/T> or
engine-A/T-ECU <A/T> is detecting a problem in a sensor or actuator, or that one
of the malfunctions listed at right has occurred.
D
Short-circuit between the engine warning lamp and
engine-ECU <M/T> or engine-A/T-ECU <A/T>
D
Malfunction
of
the
engine-ECU
<M/T>
or
engine-A/T-ECU <A/T>
OK
Replace the engine-ECU <M/T> or engine-A/T-ECU <A/T>.
No
Measure at the combination meter connector B-02.
D
Disconnect the connector, and measure at the harness side.
D
Disconnect the engine-ECU <M/T> or engine-A/T-ECU <A/T>
connector
D
Continuity between 53 and earth
OK:
No continuity
NG
Check the harness wire between combination meter and engine-
ECU <M/T> or engine-A/T-ECU <A/T> connector, and repair if
necessary.
