ENCRYPTED CODE REGISTRATION METHOD
AND RESETTING THE CODE TO THE FACTORY
SETTING
Register the encrypted code in the immobilizer-ECU and then
reset the code to the factory setting after parts have been
replaced.
Replacement partEncrypted code
Ignition keyNecessary
Immobilizer-ECUNecessary
Engine-ECU*Necessary
NOTE
*: If the engine-ECU is replaced, the immobilizer-ECU should
be replaced. Each engine-ECU has an individual information
for immobilizer-ECU, and the individual information is
registered in the immobilizer-ECU.

CHASSIS ELECTRICAL -Ignition Switch and Immobilizer System54A-13
ENCRYPTED CODE REGISTRATION METHOD
If using an ignition key that has just been newly purchased,
or if the immobilizer-ECU has been replaced, you will need
to register the encrypted codes for each ignition key being
used into the immobilizer-ECU. (A maximum of eight different
encrypted codes can be registered.)
Moreover, when the immobilizer-ECU has been replaced, you
will need to use the MUT-IIto register the password that
the user specifies into the immobilizer-ECU. (Refer to the
MUT-IIinstruction manual for instructions on using the MUT-II.)
Caution
Because registering of the encrypted codes is carried
out after all previously-registered codes have been
erased, you should have ready all of the ignition keys
that have already been registered.
1. Connect the MUT-IIto the diagnosis connector.
Caution
Turn the ignition switch to LOCK (OFF) position before
connecting or disconnecting the MUT-II.
2. Check that diagnosis code No. P1160 is not being
generated by the each engine-ECU. If it is being generated
check according to the Troubleshooting Procedures.
(Refer to GROUP 13A - Troubleshooting.)
3 Use the ignition key that is to be registered to turn on
the ignition switch.
4. Use the MUT-IIto register the encrypted 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. Turn off the ignition switch.
6. Check that the engine can be started with each of the
ignition keys.
7. Check the diagnosis output from the each engine-ECU,
and erase code No. P1160 if it appears. (Refer to GROUP
13A - Troubleshooting.)
8. Disconnect the MUT-II. This completes the registration
operation.

SPEEDOMETER CHECK
(1) Ensure that tire pressure indicates the value of tirepressure label.
(2) Place the vehicle on speedometer teste r.
(3)
(4) For prevention of front wheel lateral runout, install
extension fittings on front towing eye and tie down hook,
and install both ends on anchor plate.
(5) For prevention of vehicle from starting out, install chain or wire (the other end of which is tightly fixed on rear
towing eye) on the vehicle.
(6) Ensure that speedometer indication range is within standard value, or pointer deflection is within limit value.
Caution
During operation, avoid excessive acceleration and
deceleration.

for detection of engine speed to connect engine speed
indicator.
2. Compare measured values of individual engine speed
with tachometer values, and ensure that indication
allowance is within standard value.
