00-9 Precautions:
Precaution for Vehicle Equipped with ESP®
System
• When testing with any of the following equipments
(when vehicle is tested by rotating wheels (tires)
under vehicle stop), be sure to deactivate ESP®
system referring to "Precautions in Speedometer Test
or Other Tests in Section 4F" to obtain correct data.
When vehicle acceleration is not sensed and wheels
are rotating, ESP® control module judges that wheels
are in slip condition and controls engine torque to
reduce by TCS control.
– 2 or 4-wheel chassis dynamometer
– Speedometer tester
– Brake tester
– Etc.
ESP® control module
• When ESP® control module is removed / installed, do
not use impact wrenches which generate shock or
impact to avoid damaging sensors in ESP® control
module.
• When any of the following operation is done, calibrate
steering angle sensor, G sensor and master cylinder
pressure sensor (in ESP® control module) referring to
"Sensor Calibration in Section 4F".
– When battery or dome fuse is removed.
– When steering angle sensor is replaced.
– When ESP® control module is removed.
– When yaw rate / G sensor assembly is removed.
Precautions for Catalytic Converter (Petrol
Engine Model)
For vehicles equipped with a catalytic converter, use
only unleaded gasoline and be careful not to let a large
amount of unburned gasoline enter the converter or it
can be damaged.
• Conduct a spark jump test only when necessary,
make it as short as possible, and do not open the
throttle.
• Conduct engine compression checks within the
shortest possible time.
• Avoid situations which can result in engine misfire
(e.g. starting the engine when the fuel tank is nearly
empty.)
Precautions for Catalytic Converter and Diesel
Particulate Filter (Diesel Engine Model)
• Use only specified fuel and be careful not to let a large
amount of unburned fuel enter the converter and filter
or they can be damaged.
• Be careful not to expose catalytic converter and diesel
particulate filter to excessive shock to avoid an
damage to them.

Precaution for CAN Communication System

• The loose (1) in the wire harnesses twist of the CAN
S6JB0A0000004
lines except around the connector (3) should be within
100 mm (3.9 in.). Refer to the wiring diagram for the
CAN lines discrimination. Excessively-loosed lines
may be influenced by the electric noise.
• Do not connect terminals of the CAN line using a
bypass wire (1). Otherwise, the CAN line may be
influenced by the electric noise.

Precautions for Electrical Circuit Service

S6JB0A0000005
• When replacing a fuse, make sure to use a fuse of the
specified capacity. Use of a fuse with a larger capacity
will cause a damage to the electrical parts and a fire.
