TROUBLESHOOTING METHOD

The engine operation is not normal and the
engine trouble warning light comes on.

1. Check:

• Fault code number

▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼

a. Check the fault code number displayed on 

the meter.

b. Identify the faulty system with the fault 

code.

c. Identify the probable cause of the malfunc-

tion.

▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲

2. Check and repair the probable cause of 

malfunction.

3. Perform fuel injection system reinstatement 

action.
Refer to “Reinstatement method” of table in 
“TROUBLESHOOTING DETAILS” on page 
8-45.

4. Turn the main switch to “OFF” and back to 

“ON”, then check that no fault code number 
is displayed.

TIP

If fault codes are displayed, repeat steps (1) to 
(4) until no fault code number is displayed.

5. Erase the malfunction history in the diag-

nostic mode. Refer to “Sensor operation 
table (Diagnostic code No. D:62)”.

TIP

Turning the main switch to “OFF” will not erase 
the malfunction history.

The engine operation is not normal but the
engine trouble warning light does not come
on.

1. Check the operation of following sensors 

and actuators in the Diagnostic mode. 
Refer to “Sensor operation table” and 
“Actuator operation table”.

If a malfunction is detected in the sensors 
or actuators, repair or replace all faulty 
parts.
If no malfunction is detected in the sensors 
and actuators, check and repair inner parts 
of the engine.

Fault code No.

No fault code No.

Check and repair.
Refer to “TROUBLE-
SHOOTING 
DETAILS” on page 8-
45.
Monitor the operation 
of the sensors and 
actuators in the diag-
nostic mode. Refer to 
“Sensor operation 
table” and “Actuator 
operation table”.

Check and repair.
