PERFORM SPEC IN DATA MONITOR MODE

With CONSULT

Make sure that “MASS AIR FLOW SENSOR (Hz)”, “B/FUEL SCHDL” and “A/F ALPHA-B1” are within the SP

value using CONSULT in “SPEC” of “DATA MONITOR” mode. Refer to 

EC-785, "Component Function

Check"

.

Is the measurement value within the SP value?

YES

>> GO TO 9.

NO

>> GO TO 8.

8.

DETECT MALFUNCTIONING PART BY TROUBLE DIAGNOSIS - SPECIFICATION VALUE

Detect malfunctioning part according to

>> GO TO 10.

10.

DETECT MALFUNCTIONING PART BY DIAGNOSIS PROCEDURE

Inspect according to Diagnosis Procedure of the system.

NOTE:

The Diagnosis Procedure in EC section described based on open circuit inspection. A short circuit inspection

is also required for the circuit check in the Diagnosis Procedure. For details, refer to Circuit Inspection in 

GI-

48, "Circuit Inspection"

.

Is malfunctioning part detected?

YES

>> GO TO 11.

NO

>> Monitor input data from related sensors or check the voltage of related ECM terminals using CON-

SULT. Refer to 

EC-679, "Reference Value"

.

11.

REPAIR OR REPLACE THE MALFUNCTIONING PART

1. Repair or replace the malfunctioning part.

2. Reconnect parts or connectors disconnected during Diagnosis Procedure again after repair and replace-

.

NO-2 >> I/M examination, requested from the customer: GO TO 13.

13.

PREPARE FOR I/M EXAMINATION

1. Set SRT codes. Refer to

Diagnostic Work Sheet

INFOID:0000000012198253

DESCRIPTION

There are many operating conditions that lead to the malfunction of

engine components. A good grasp of such conditions can make trou-

bleshooting faster and more accurate.

In general, each customer feels differently about a incident. It is

important to fully understand the symptoms or conditions for a cus-

tomer complaint.

Utilize a diagnostic worksheet like the one on the next page in order

to organize all the information for troubleshooting.

Some conditions may cause the MIL to come on steady or blink and

DTC to be detected. Examples:

• Vehicle ran out of fuel, which caused the engine to misfire.

• Fuel filler cap was left off or incorrectly screwed on, allowing fuel to

evaporate into the atmosphere.
