All ignition keys can be registered with MUT-III.
Additional ignition keys can be registered with
MUT-III.
Registration with the MUT-III
CAUTION
To prevent damage to MUT-III, always turn the
ignition switch to "LOCK" (OFF) position before
connecting or disconnecting MUT-III.
NOTE: .
•Before registration, check that no diagnosis code
is set. If a diagnosis code is set, resolve the
problem beforehand.
•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-III 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.

13.Disconnect MUT-III.Registration of additional key(s) without
using the MUT-III
If the MUT-III is not available, new key(s) can be
registered by operating two keys which have been
registered to the vehicle (A maximum of eight keys
can be registered to one vehicle). Follow the
procedure below to register new key(s) to the
vehicle.
NOTE: The registered key is the key that allows you
to start the engine.
1. Turn "ON" the ignition switch by using the first
registered key (key A), and wait for five seconds.
2. Remove the first registered key (key A).
3. Insert the second registered ignition key (key B),
and turn it to the ON position.
4. The immobilizer-ECU identifies the new key to
accept or reject it, and operates the immobilizer
indicator (See the table below).
5. If a new ignition key is registered further, repeat
steps 1 to 7 above.
A maximum of eight ignition keys can be registered
to one vehicle (If you attempt to register the ninth
key, the immobilizer-ECU rejects the key). If any of
the following conditions are satisfied, the additional
key registration mode will terminate:
•The ignition switch has been on for more than 30
seconds.
•After the ignition key has been turned to the
"LOCK" (OFF), the engine control relay is turned
off.
•The MUT-III has started communicating with
vehicle systems.
6. After the registration mode has terminated, the
additionally registered key(s) should allow you to
start the engine.

TECHNICAL DESCRIPTION (COMMENT)
The engine-ECU and its associated components, the
combination meter assembly, the wiring harness, or
the connector(s) may be defective.
TROUBLESHOOTING HINTS
•Malfunction of the vehicle speed sensor
•Malfunction of the engine-ECU
•Malfunction of the combination meter assembly
•The wiring harness or connectors may have
loose, corroded, or damaged terminals, or
terminals pushed back in the connector.
DIAGNOSIS PROCEDURE
STEP 1. MUT-II/III actuator test.
(1) Connect the MUT-II/III to the diagnosis connector.(2) Use the MUT-II/III to enter simulated vehicle
speed.
Q: Does the speedometer show that simulated vehicle
speed?
YES :
Go to Step 6.
NO : Go to Step 2.
STEP 2. Check the vehicle speed sensor.
(MUT-II/III diagnosis code)
(1) Connect MUT-II/III to the diagnosis connector.
(2) Turn the ignition switch to the "ON" position.
(3) Read the MPI system diagnosis code.
Q: Is MPI system diagnosis code P0500 set?
YES :
Refer to P.13A-186 <4G1> or P.13B-166
<4G6>.
