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.

CHASSIS ELECTRICAL -Headlamp Assembly54A-28
HEADLAMP INTENSITY MEASUREMENT
1. Using a photometer, and following its manufacture’s
instruction manual.
2. Maintain an engine speed of 2,000 r/min., with the battery
in the charging condition
3. Set the headlamps to high beam
4. Measure the headlamp centre intensity (a point of H line
and V line) and check to be sure that the limit value
is satisfied.
Limit:
High beam 30,000 cd or more per one headlamp
NOTE
1. There may be special local regulations pertaining to
headlamp intensity, be sure to make any adjustments
necessary to satisfy such regulations.
2. If an illuminometer is used to make the measurements,
convert its values to photometer values by using the
following formula.
I=Er
2Where:
I=intensity (cd)
E=illumination (lux)
r=distance (m) from headlamps to illuminometer
Caution
1. On the headlamp not yet adjusted, perform aiming
with connector removed and the lamps switched off,
if applicable. In addition, care should be taken to
prevent a change of optical axis when connector is
reconnected.
2. Plastic outer lens are equipped with headlamps. When
lens surface is covered with materials for not
penetrating light, headlamp operation time should be
within 3 minutes. In addition, masking such as taping
should not be performed.
HEADLAMP BULB (LOW BEAM)REPLACEMENT
(1) Disconnect battery.
(2) Disconnect connector.
(3) Screw out socket to pull out bulb.
(4) After bulb is replaced, properly reconnect connector.
Caution
Do not touch bulb surface bare-handed or with dirty
gloves. If dirt is attached on glass surface of the bulb,
immediately use alcohol or thinner to remove dirt, and
install the bulb after well dried.
