System DiagramEFS0019X
ESP FunctionEFS0019W
1. The Electronic Stability Program is called the ESP for short. ESP is indicated as ESP on CONSULT-II
screen.
2. In addition to the ABS/TCS function, ESP detects a driver's steering operation amount and brake opera-
tion amount from steering angle sensor and pressure sensor. Using the information from yaw rate/side G
sensor and wheel sensors, ESP judges the driving condition (conditions of understeer and oversteer) to
improve the stability by controlling brake on 4 wheels and engine output.
3. During ESP operation, SLIP indicator lamp flashes to inform the driver of the operation.
CAUTION:

During ESP operation, body and the brake pedal lightly vibrate and their mechanical noise may be
heard. This is a normal condition.

If vehicle is rotated on a turn table, or rolled and rocked on a ship, the ABS warning lamp,
ESP OFF indicator lamp, and SLIP indicator lamp may turn on. In this case, start engine on a nor-
mal road again. If the ABS warning lamp, ESP OFF indicator lamp, and SLIP indicator lamp turn
off after the restart, it is normal.

When driving in a steep slope such as a bank, ABS warning lamp, ESP OFF indicator lamp, and
SLIP indicator lamp may turn on. In this case, start the engine on a normal road again. If ABS
warning lamp, ESP OFF indicator lamp, and SLIP indicator lamp turn off after the restart, it is nor-
mal.
TCS FunctionEFS0019V
1. With the wheel sensor signals from 4 wheels, the ESP/TCS/ABS control unit detects a wheel spin. If a
wheel spins, the control unit controls brake fluid pressure to the spinning wheel, and cuts the fuel to the
engine. It also closes the throttle valve to reduce the engine torque. Furthermore, throttle position is con-
trolled to the appropriate engine torque.
2. If a wheel spins, the TCS system works and function by applying brake fluid pressure to the spinning
wheel.

Removal and InstallationEFS001CD
REMOVAL
Pay attention to the following when removing sensor.
CAUTION:

As much as possible, avoid rotating sensor when removing it. Pull sensors out without pulling on
sensor harness.

Take care to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avoid damage to sensor wiring and loss of sensor
function.
INSTALLATION
Pay attention to the following when installing sensor. Tighten installation bolts to specified torques.

When installing, check that there is no foreign material such as iron chips on pick-up and mounting hole of
the sensor. Check that no foreign material has been caught in the sensor rotor. Remove any foreign mate-
rial and clean the mount.

When installing front sensor, be sure to press rubber grommets in until they lock at the three locations
shown in the figure (2 at strut and 1 at body panel). When installed, harness must not be twisted.
