MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TROUBLESHOOTING STRATEGY

M1131150002553

NOTE: If a DTC is erased, its "freeze frame" data will
also be erased and system readiness test status will
be reset. Store the "freeze frame" data before eras-
ing the DTC.
Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will be sure to have
exhausted most of the possible ways to find an MFI
fault.
1. Gather as much information as possible about the

complaint from the customer.

2. Verify that the condition described by the

customer exists.

3. Check the vehicle for any MFI Diagnostic Trouble

Code (DTC).

4. If you cannot verify the condition and there are no

DTCs, the malfunction is intermittent. For
information on how to cope with intermittent
malfunctions, refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points

− How

to Cope with Intermittent Malfunctions

P.00-15

5. If you can verify the condition but there are no

DTCs, or the system cannot communicate with
the scan tool, refer to the trouble symptom
classification table.

6. If there is a DTC, store the number of the code,

then erase the code from the memory using the
scan tool.

7. Reconfirm the malfunction symptom and carry out

a test drive with the drive cycle pattern.

8. If DTC is set again, carry out an inspection with

appropriate diagnostic trouble code procedures.

9. If DTC is not set again, the malfunction is

intermittent. For information on how to cope with
intermittent malfunctions, refer to GROUP 00,
How to Use Troubleshooting/Inspection Service
Points

− How to Cope with Intermittent

Malfunctions

P.00-15

10.After repairs are completed, conduct a road test

duplicating the complaint set conditions to confirm
the malfunction has been corrected.

11.Erase the permanent DTC. (Refer to

DIAGNOSTIC FUNCTION

− PERMANENT DTC

for the procedures of erasing the permanent DTC

P.13A-11

NOTE: This is carried out to prevent the failure to
pass the Inspection and Maintenance (I/M) test in
the states checking whether the permanent DTC
is stored or not.

NOTE: If the engine control module (ECM) is
replaced, Immobilizer Encrypted Code Registration
should be carried out, refer to GROUP 42B, Diagno-
sis
