Transmitter Recognition Code Registration Function

The table below shows the 4 special coded ID registration function modes through which up to 4 different
codes can be registered. The codes are electronically registered (written to and stored) in the EEPROM.
For details of the recognition code registration procedure, refer to the 2002 LEXUS ES300 Repair Manual
(Pub. No. RM911U) to register the codes correctly.

Mode

Function

Rewrite Mode

Erases all previously registered codes and registers only the newly received
codes. This mode is used whenever a transmitter or the Body ECU is replaced.

Add Mode

Adds a newly received code while preserving any previously registered codes.
This mode is used when adding a new transmitter. If the number of codes
exceeds 4, the oldest registered code is erased first.

Confirm Mode

Confirms how many codes are currently registered. When adding a new code,
this mode is used to check how many codes already exist.

Prohibit Mode

To delete all the registered codes and to prohibit the wireless door lock
function.
This mode is used when the transmitter is lost.

AERODYNAMICS

To improve aerodynamic performance, the following measure have been taken.

The shape of the front bumper has been optimized to collect the flow of air from under the floor and the

sides of the body.

The flattened under body smoothly guides the under-the-car air flow towards the rear.
The shape of the rear bumper has been optimized so as not to obstruct the flow of air under the floor.

LIGHTWEIGHT AND HIGH RIGID BODY

High strength sheet steel has been used in order to ensure body rigidity and realize a lightweight body.

SAFETY FEATURE

1. Impact Absorbing Structure for Frontal Collision

The impact absorbing body structure of the ’02 ES300 can effectively help absorb the energy of impact in
the event of a frontal or side collision. This structure also realizes high-performance occupant protection
through the use of reinforcements and members that help to minimize cabin deformation.

2. Impact Absorbing Structure for Side Collision

Impact energy of a side collision directed to the cabin area is dispersed throughout the body via pillar

reinforcements, side impact protection beams, floor cross members, thus helping minimize the impact
energy finally directed to the cabin.

A Head Impact Protection Structure has been adopted. With this type of construction, if the occupant’s

head hits against the roof side rail and pillar in reaction to a collision, the inner panel of the roof side rail
and pillar collapses to help reduce the impact.
