CHASSIS ELECTRICAL ± Ignition Switch and Immobilizer System54-16
Inspection Procedure 3
Engine does not start (Cranking but no initial combus-
tion).
Probable cause
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.
Malfunction of MPI system

Malfunction of immobilizer-ECU
Check the system voltage during crank-
ing
OK:8 V or moreNGCheck the battery.

Check the immobilizer-ECU power
source and the earth circuit. (Refer to
P.54-17, Inspection Procedure 5.)OKCheck trouble symptom.NGReplace the immobilizer-ECU.
Register the password (secret code)
and the ID code. (Refer to P.54-23.)
Inspection Procedure 4
Engine does not start (Cranking but no initial combus-
tion).
Probable cause
If no fuel injection, there might be a problem with the fuel injection 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.
Malfunction of diesel fuel injection system

Check the harness between the immobi-
lizer-ECU and engine control relay, and
repair if necessary.

Check the harness between the immobi-
lizer-ECU and junction block, and repair
if necessary.
(2) NG

3. Use the ignition key that is to be registered to turn on
the ignition switch.
4. Use the MUT-II to register the ID code. If you are
registering two or more codes, use the next key to the
registered to turn on the ignition switch without
disconnecting the MUT-II.
5. Disconnect the MUT-II. This complete the registration
operation.
6. Check that the engine can be started with each of the
ignition keys.
7. Check the diagnosis output from the engine-ECU, and
erase code No.54 if it appears.
Resetting the code to the factory setting

Refer to the MUT-II INSTRUCTION MANUAL on handling
the MUT-II.
NOTE
Resetting the code to the factory setting refers to the process
of clearing the identification code which has been recorded
in the fuel cut valve controller and switching the controller
to learning mode. After this resetting is carried out, the
identification code in the immobilizer-ECU will be recorded
in the controller the next time the ignition switch is turned
to the ON.
1. Connect the MUT-II to the diagnosis connector.
Caution
Turn off the ignition switch before connecting or
disconnecting of the MUT-II.
2. Turn on the ignition switch.
3. Use the MUT-II to reset the code to the factory setting.
NOTE
Approximately 16 minutes are required to complete
resetting the code to the factory setting.
4. Disconnect the MUT-II
