CAN Communication System Description

S6JB0A4601004

Refer to “CAN Communication System Description: For Petrol Engine Model in Section 1A” for CAN communication
system description. ESP

® control module communicates control data with each control module as follows.

ESP

® Control Module Transmission Data

ESP

® Control Module Reception Data

ESP

® OFF light

• If ESP

® OFF switch is turned “ON”, the ESP® OFF light light up. When it is

“ON”, TCS and stability control system functions are controlled not to work.
However, when the speed is over 30 km/h (18.5 mph), ESP

® OFF light is

turned “OFF” and TCS and stability control system function is back to work
automatically.

• When transfer shift position (if equipped) is in 4L-lock, the ESP

® OFF light light

up to indicate engine torque down and stability control system in TCS are
controlled not to activate to increase the driving force.
However, the brake-traction control works through ESP

® OFF light light up.

• ESP

® OFF light light up to indicate that brake control of traction control

function is controlled not to act if brake pad temperature is over 350

°C (662 °F)

and any of wheel is in wheel spin condition.

CAN Communication System For Electronic Stability Program Description

S6JB0A4601005

There is CAN communication system only for ESP

® control module (1) and yaw rate / G sensor assembly (2).

This CAN communication system is independent from other control modules.

ESP

® communicates control data with yaw rate / G sensor assembly as follows.

ESP

® Transmission Data to Yaw Rate / G Sensor Assembly

• Longitudinal G neutral position
• Lateral G neutral position

ESP

® Reception Data from Yaw Rate / G Sensor Assembly

• Vehicle yaw rate signal
• Vehicle longitudinal G signal
• Vehicle lateral G signal
• Yaw rate / G sensor assembly related malfunction
