TROUBLE JUDGMENT

Check Condition

• More than 2 seconds have passed since the igni-

tion switch was turned to "ON" position.

• Battery positive voltage is more than 10 V.

Judgement Criterion

• Unable to receive EPS-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 EPS-ECU, by malfunc-
tion in the power supply system of EPS-ECU, in 
EPS-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 EPS-ECU and 
malfunction in the power supply system of 
EPS-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 ).

TROUBLESHOOTING

MULTIPOINT FUEL INJECTION (MPI)

13A-118

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. 
Therefore, check CAN bus line as in the case of 
response to intermittent malfunctions (Refer to 
GROUP 00 

−

 How to Use Troubleshoot-

ing/Inspection Service Points 

−

 How to Cope with 

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 

−

 Explanation about the M.U.T.-III CAN Bus
