56CHASSISÐMANUAL TRANSAXLE
MANUAL TRANSAXLE
 DESCRIPTION
The 5S±FE engine model uses the same S51 manual transaxle as in the previous model.
The 1MZ±FE engine model ahs newly adopted the E153 manual transaxle. The basic construction and operation
of the E153 manual transaxle are the same as those of the '95 MR2. However, the differential gear ratio has been
changed to accommodate the characteristics of the engine.

In addition to the TWC that is provided under the floor of the previous model, WU-TWCs are provided
to reduce exhaust emissions soon after the engine is started.
The WU-TWC for the right bank is provided in the front exhaust pipe and in the exhaust manifold for
the left bank.
The WU-TWC uses a thin-foil (foil thickness 50

ENGINE IMMOBILISER SYSTEM
1. General
The engine immobiliser system is a theft-deterrent system which disables the engine from starting using the
ignition key with an ID code that matches is the pre-registered code in the vehicle.
This system adopts a transponder system which uses a transponder chip embedded in the grip of the ignition
key. When the coil located around the ignition key cylinder receives the ID code signal transmitted by the
transponder chip, the computer included in the ECM determines whether or not the ID code matches the code
stored in the computer.

3. Wiring Diagram
4. Construction
The engine immobiliser system consists of the transponder key (ignition key), transponder key coil, trans-
ponder key amplifier, and ECM.
Transponder Key (Ignition Key)
A transponder chip is embedded in the grip of the
ignition key. Each transponder chip contains an
individual transponder key-code (ID code). The
key does not need an internal battery to transmit
a key code.
Transponder Key Coil and Transponder Key Amplifier
The transponder key coil is a ring-shaped coil installed around the ignition key cylinder. The transponder
key amplifier is installed in the back of the key cylinder.
An electrical power circuit to provide power to the transponder key coil has been enclosed in the amplifier.
ECM
The control circuit of the engine immobiliser system has been integrated inside the ECM. As a result, the
time has been reduced taken for the engine to start in case of mismatching key code thus improving the
system's theft deterrent performance.
A maximum of 10 different transponder key codes (master key: 7 types, sub key: 3 types) can be registered
in the ECM.

5. Operation
Setting the Engine Immobiliser System
When the ignition key is removed from the key cylinder, the engine immobiliser system will be set.
Unsetting the Engine Immobiliser System
1
When the ignition key is inserted in the key cylinder, the ECM instructs the transponder key coil to sup-
ply the electromagnetic energy that enables the transponder chip to transmit a key-code signal. The
transponder chip then uses this electrical energy to transmit a key-code signal.
2
The key-code signal that has been received at the coil is amplified by the transponder key amplifier and
sent to the ECM. The key-code that has been received by the ECM is then compared to the key-code
that is stored in the ECM. The code comparison process takes place and if the codes match in a row,
the ECM unsets the immobiliser system. As a result, the engine will be able to start.
