2005 MITSUBISHI LANCER Fuel System Diagnosis

IGNITION SWITCH
CHASSIS ELECTRICAL54A-18
INSPECTION PROCEDURE 2: The Ignition Key cannot be Registered.
TECHNICAL DESCRIPTION (COMMENT)
The ignition key transponder or the immobilizer-ECU
is suspected to be defective.
TROUBLESHOOTING HINTS
•Malfunction of the ignition key
•Malfunction of immobilizer-ECU
DIAGNOSIS PROCEDURE
STEP 1. MUT-II/III diagnosis code.
Q: Does diagnosis code No.11 reset?
YES :
Refer to P.54A-9.
NO : Replace the ignition key that cannot be
registered. Then re-register the encrypted
code. (Refer to P.54A-20). Verify that the
ignition key can be registered, then Go to
Step 2.
STEP 2. Retest the system.
Q: Does registered ignition key function properly?
YES :
The procedure is complete. (If no
malfunctions are found in all steps, an
intermittent malfunction is suspected. Refer
to GROUP 00, How to Use
Troubleshooting/Inspection Service Points −
How to Cope with Intermittent Malfunction
P.00-5).
NO : Replace the immobilizer-ECU.
INSPECTION PROCEDURE 3: Engine does not Start (Cranking but no Initial Combustion).
TECHNICAL DESCRIPTION (COMMENT)
If the fuel injectors are not operating, there might be
a problem with the MPI system in addition to a
malfunction of the immobilizer system. It is normal for
this to occur if an attempt is made to start the engine
using a key that has not been properly registered.
TROUBLESHOOTING HINTS
•Malfunction of MPI system
•Malfunction of immobilizer-ECU
DIAGNOSIS PROCEDURE
STEP 1. Check the system voltage.
Measure the system voltage during cranking.
Q: Is the voltage 8 volts or more?
YES :
Go to Step 2.
NO : Check the battery. Refer to P.54A-4. The
engine should start.
STEP 2. Check the immobilizer system diagnosis
code and MPI system diagnosis code.
Q: Which diagnosis code resets, the immobilizer
system diagnosis code or the MPI system
diagnosis code?
Immobilizer system diagnosis code is set :
Refer
to P.54A-9.
MPI system diagnosis code is set : Refer to
GROUP 13A, Diagnosis P.13A-15, GROUP
13B, Diagnosis P.13B-15.
No diagnosis code is set : Go to Step 3.
STEP 3. Check the starting system.
Q: Does the engine start?
YES :
Go to Step 4.
NO : Refer to GROUP 13A, Diagnosis −
Symptom Chart P.13A-215, GROUP 13B,
Diagnosis − Symptom Chart P.13B-189. If
the malfunction is not resolved, replace the
immobilizer-ECU. Then register the
password (secret code) and encrypted
code. (Refer to P.54A-20.) The engine
should start.

ON-VEHICLE SERVICE
HOW TO REGISTER ENCRYPTED CODEM1543008100410
CAUTION
Because registering the encrypted codes is done
after all previously-registered codes have been
erased, you should keep all of the ignition keys
that have already been registered accessible.
If the ignition key, Immobilizer-ECU,
engine-ECU or engine-A/T-ECU is
replaced or an ignition key is added, encrypted
codes of all the ignition keys must be registered. (A
maximum of eight different ignition key can be
registered.) Moreover, when the immobilizer-ECU
has been replaced, you will need to use MUT-II/III to
register the immobilizer-ECU and input the vehicle
secret code and to register the password (secret
code) that the owner specifies into the
immobilizer-ECU.
If an attempt is made to start the engine with an
unregistered ignition key, cranking occurs, but fuel
supply is cut off to disable the engine. In
approximately.
NOTE: Engine-ECU or engine-A/T-ECU
has an encrypted code for immobilizer-ECU, and the
encrypted code is registered in the immobilizer-ECU
and ignition key.
POINTS TO NOTE DURING OPERATION
If none of the functions can be used, check the
diagnosis codes, and after carrying out any
necessary repairs, repeat the operation.
If an incorrect password is input ten times in a row,
the immobilizer-ECU judges that an unauthorized
operation is being attempted. Start-prevention mode
will be set, and engine operation will stop and all
special functions will be disabled. If the ignition
switch is turned to "ON" position, "Unauthorized
operation, start- prevention mode" will be cancelled.
KEY ID (ENCRYPTED CODE)
REGISTRATION
All ignition keys can be registered with MUT-II.
Additional ignition keys can be registered with
MUT-II.
Registration with the MUT-II
CAUTION
To prevent damage to MUT-II, always turn the
ignition switch to "LOCK" (OFF) position before
connecting or disconnecting MUT-II.
NOTE: .
•Using the key ID register function will cause all
key IDs that have been previously registered in
the immobilizer-ECU to be erased. All keys need
to be registered. Those which have been
registered before should be on hand before using
this function.
•If registering more than one key, do not
disconnect MUT-II halfway through the
registration process.
•After registering key IDs, check that the engine
can be started using all of the keys that have
been registered. If the engine will not start, refer
to Immobilizer System Diagnosis P.54A-6.
1. Connect MUT-II to diagnosis connector (16- pin).
2. Turn the ignition switch to "ON" position.
3. At "System Select," press "YES"
