FINAL CHECK

Perform the “DTC confirmation procedure” or “Component Inspection” to check that the repair is correctly per-
formed. Check that malfunctions are not reproduced when obtaining the malfunction information from the cus-
tomer, referring to the symptom inspection result in step 3 or 4. 
Is the check result normal?

YES

>> Trouble diagnosis is completed.

NO-1

>> The DTC is reproduced. GO TO 7.

NO-2

>> The symptom is reproduced. GO TO 6.

INFOID:0000000005236138

System Description

INFOID:0000000005236139

Description

• The Continuous Damping Control system mainly consists of the components such as the E-SUS control

unit, front body vertical G sensor, front wheel vertical G sensor, rear body vertical G sensor, and shock
absorber actuators on each wheel. 

• It calculates the command values to be transmitted to the shock absorber actuator on each wheel based on

the information from ECM, ABS actuator and electric unit (control unit) and steering angle sensor via CAN
communication and information from the front body vertical G sensor, front wheel vertical G sensor and rear
body vertical G sensor. 

• The shock absorber actuator on each wheel controls the damping force based on the command values cal-

culated by E-SUS control unit. 

• Can perform the self-diagnosis with CONSULT-III. 
• Communicates the signal from each control unit via CAN communication.

Operation principle

Controls damping force by changing the oil passage cross section area through control of orifice by solenoid
core activation. 

Operation characteristics

• Changes the damping force control by switching the switch (AUTO

mode or SPORT mode). 

• Changes the damping force depending on the output current to the

shock absorber actuators. 

ECM

Transmits mainly the following signals to E-SUS control unit via CAN communication. 
• Requested torque signal

Unified meter and A/C amp.

Transmits mainly the following signals from E-SUS control unit via CAN communication. 
• Sport mode indicator lamp signal
