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

INSPECTION PROCEDURE FOR TROUBLE SYMPTOMS
Inspection Procedure 1
Tachometer does not work.
Probable cause
The ignition signal may not be input from the engine, or there may be a malfunction
in the power supply or earth circuit.
Malfunction of tachometer

Malfunction of harness or connector
Disconnect the combination meter con-
nector C-04 and measure at the harness
sides.
