Data link

connector

(1)

Connect the Scan tool to the data link connector.

(2)

When the power of V.C.I. is turned to ON, the indicator lamp
of the V.C.I. illuminates in green.

The indicator lamp of the V.C.I. illuminates in green.

Q:Is the indicator lamp of the V.C.I. illuminates in green?

YES:

 Go to Step 2.

NO:

 Use scan tool, perform CAN bus line diagnosis.

STEP 2. Measure the battery positive voltage.

(1)

Measure the battery positive voltage during cranking.

The voltage should be 8 volts or more.

Q:Is the measured voltage 8 volts or more?

YES:

 Go to Step 3.

NO:

 Check the battery. Refer to GROUP 54A, Battery -

Battery Check P.54Aa-2. Then confirm that the
malfunction symptom is eliminated.

(1)

Measure voltage between terminal No. 16 and ground.

Voltage should be battery positive voltage.

Q:Is  battery  positive  voltage  (approximately  12  volts)

present?

YES:

 Go to Step 4.

NO:

 Repair an open circuit between ETACS-ECU connector

C-317 (terminal No. 8) and data link connector C-125
(terminal No. 16).Then confirm that the malfunction
symptom is eliminated.

STEP 4. Check the continuity at data link connector C-125.

(1)

Check for the continuity between terminal No. 4, No. 5 and
ground.

Should be less than 2 ohms.

Q:Does continuity exist?

YES:

 Check and replace the scan tool. Then confirm that

the malfunction symptom is eliminated.

NO:

 Repair an open circuit or harness damage between data

link connector C-125 (terminal No. 4, No. 5) and ground.
Then confirm that the malfunction symptom is eliminated.

INSPECTION PROCEDURE 2: The Malfunction Indicator Lamp (SERVICE ENGINE
SOON or Check Engine Lamp) Does Not Illuminate Right after the Ignition Switch Is
Turned to the "ON" Position.

M11310100056USA0000010000

 

CIRCUIT OPERATION

The  combination  meter  causes  the  malfunction
indicator lamp (SERVICE ENGINE SOON or Check
Engine  Lamp)  to  illuminate  for  5  seconds
immediately after the ignition switch is turned to the
"ON" position occurred.

TROUBLESHOOTING HINTS (The most likely
causes for this case:)

Malfunction  of  the  malfunction  indicator  lamp
(SERVICE  ENGINE  SOON  or  Check  Engine
Lamp).

Open  or  shorted  malfunction  indicator  lamp
(SERVICE ENGINE SOON or Check Engine Lamp)
circuit.

 

DIAGNOSIS

STEP 1. Check the trouble symptoms.

(1)

Turn the ignition switch to the "ON" position.

13Ab-756

MULTIPORT INJECTION SYSTEM (MFI) <DIAGNOSIS>

SYMPTOM PROCEDURES

The malfunction indicator lamp (SERVICE ENGINE SOON
or Check Engine Lamp) should illuminate immediately after
the ignition switch is turned to the "ON" position.

(2)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Does the malfunction indicator lamp (SERVICE ENGINE

SOON or Check Engine Lamp) illuminate?

YES:

 It can be assumed that this malfunction is

intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points - How to Cope
with Intermittent Malfunctions P.00-15.

NO:

 Replace the combination meter.

INSPECTION PROCEDURE 3: The Malfunction Indicator Lamp (SERVICE ENGINE
SOON or Check Engine Lamp) Remains Illuminated and Never Goes Out.

COMMENT

In cases such as the above, the cause is probably
that the ECM is detecting a problem in a sensor or
actuator, or that one of the malfunctions listed below
has probably occurred.

TROUBLESHOOTING HINTS (The most likely
causes for this case:)

Short in the malfunction indicator lamp (SERVICE
ENGINE SOON or Check Engine Lamp) circuit.

YES:

 Refer to Diagnostic Trouble Code Chart P.13Ab-44.

NO:

 Go to Step 2.

STEP 2. Check the trouble symptoms.

(1)

Turn the ignition switch to the "ON" position.

The malfunction indicator lamp (SERVICE ENGINE SOON
or  Check  Engine  Lamp)  should  go  out  when  5  seconds
have  passed  after  the  ignition  switch  was  turned  to  the
"ON" position.

(2)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Does the malfunction indicator lamp (SERVICE ENGINE

SOON or Check Engine Lamp) go out?

YES:

 It can be assumed that this malfunction is

intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points - How to Cope
with Intermittent Malfunctions P.00-15.

NO:

 Replace the combination meter.
