TROUBLESHOOTING

MULTIPOINT FUEL INJECTION (MPI)

13A-113

STEP 5. Check harness between oxygen sensor 
(front) connector terminal and engine-ECU 
connector terminal O2FL.

• Check output line for short circuit.

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Repair or replace the connector, or repair 
the damaged harness wire.

STEP 6. M.U.T.-III diagnosis code

• Reconfirmation of diagnosis code.

Q: Is the diagnosis code set?

YES : 

Replace the engine-ECU.

NO : 

Intermittent malfunction (Refer to GROUP 
00 

− How to Use 

Troubleshooting/Inspection Service Points 

− 

How to Cope with Intermittent Malfunctions 
).

STEP 7. Perform voltage measurement at 
engine-ECU connector.

• Disconnect engine-ECU connector, and connect 

special tool power plant ECU check harness 
(MB992110) to measure at connector for inspec-
tion.

• Ignition switch: "ON"

• Voltage between terminal ORLE and body earth.

OK: 0.4 

 0.6 V

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Go to Step 8.

STEP 8. Check harness between oxygen sensor 
(rear) connector terminal and engine-ECU 
connector terminal ORLE.

• Check earthing line for short circuit.

Q: Is the check result normal?

YES : 

Go to Step 9.

NO : 

Repair or replace the connector, or repair 
the damaged harness wire.

STEP 9. Check harness between oxygen sensor 
(rear) connector terminal and engine-ECU 
connector terminal O2RL.

• Check output line for short circuit.

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Repair or replace the connector, or repair 
the damaged harness wire.

Code No. P2530: Ignition Switch-IG1 Circuit

CAUTION

• When the ETACS-ECU of vehicles without 

KOS is replaced, the encrypted code of the 
ignition key needs to be registered to the 
ETACS-ECU. (If the encrypted code is not reg-
istered, the engine cannot be started. Regis-
ter the encrypted code as described in 
GROUP 54A, Immobilizer System 

 How to 

Register Key ID .)

OPERATION

• When the ignition switch is turned on, the ignition 

switch ON signal is input into the engine-ECU 
connector terminal IGN and also into the 
ETACS-ECU.

FUNCTION

• The engine-ECU compares the ignition switch 

ON signal sent from the ignition switch <Vehicles 
without KOS> or OSS-ECU <Vehicles with KOS> 
with ignition switch information sent from 
ETACS-ECU. The engine-ECU checks for the 
abnormality.

TROUBLE JUDGMENT

Check Condition

• Ignition switch: "ON" → "LOCK" (OFF)

Judgement Criterion

• While the ignition switch ON signal is input into 

the engine-ECU, the ignition switch information, 
sent from the ETACS-ECU via CAN, is turned to 
OFF from ON. This allows the CAN to be 
stopped.

surely perform CAN bus line diagnosis.

CAUTION

Replace ECU after certainly confirming that the 
communication circuits are normal.

TROUBLE JUDGMENT

Check Conditions

• More than 2 seconds have passed since the igni-

tion switch was turned to "ON" position.

• Battery positive voltage is more than 10 V and is 

less than 16 V.

Judgement Criterion

• Unable to receive CVT-ECU signals through the 

CAN bus line for 4 seconds.

COMMENTS ON TROUBLE SYMPTOM

Current malfunction

• The failure is possibly caused by malfunction of 

the harness and connector in CAN bus line 
between engine-ECU and CVT-ECU, by malfunc-
tion in the power supply system of CVT-ECU, in 
CVT-ECU itself, in engine-ECU.

Past malfunction

• Proceed with troubleshooting focusing on mal-

function of the harness and connector in CAN 
bus line between engine-ECU and CVT-ECU and 
malfunction in the power supply system of 
CVT-ECU. For diagnosis procedure, refer to how 
to cope with past malfunctions. (Refer to GROUP 
00 

− How to Use Troubleshooting/Inspection 

Service Points 

− How to Treat Past Trouble ).

NOTE: In the case of past malfunctions, M.U.T.-III 

CAN bus line diagnosis cannot detect a malfunc-
tion even if there is a malfunction in CAN bus.

response to intermittent malfunctions (Refer to 
GROUP 00 

 How to Use Troubleshoot-

ing/Inspection Service Points

Intermittent Malfunctions ). It is possible to nar-
row down areas with a high possibility of malfunc-
tions from diagnosis codes set to each ECU that 
performs CAN communication (Refer to GROUP 
54C
