DYNAMIC STABILITY CONTROL 

2)

Measure voltage at output terminal D and 
ground terminal E when the yaw rate 
sensor is rotated left and right.

Caution

• Be careful when turning the yaw rate 

sensor rotation position while it is in a 
reversed state because the rotation 
direction and voltage will be reversed.

Voltage

Right rotation:

 fluctuation between 2.5—4.62 V

Left rotation: 

fluctuation between 2.5—0.33 V

ABS (ABS/TCS) ON-BOARD DIAGNOSIS

A6E697567650W02

On-Board Diagnostic (OBD) Test Description

• The OBD test inspects the integrity and function of the ABS (ABS/TCS) and outputs the results when 

requested by the specific tests.

• On-board diagnostic test also:

— Provides a quick inspection of the ABS (ABS/TCS) usually performed at the start of each diagnostic 

procedure.

— Provides verification after repairs to ensure that no other faults occurred during service.

• The OBD test is divided into 3 tests:

— Read/clear diagnostic results, PID monitor and record and active command modes.

Read/clear diagnostic results

• This function allows you to read or clear DTCs in the ABS (ABS/TCS) HU/CM memory.

PID/data monitor and record

• This function allows you to access certain data values, input signals, calculated values, and system status 

information.

Active command modes

• This function allows you to control devices through the WDS or equivalent.

Reading DTCs Procedure

1. Connect WDS or equivalent to the vehicle DLC-2 

16-pin connector.

2. Retrieve DTC by WDS or equivalent.

Clearing DTCs Procedures

1. After repairs have been made, perform the DTCs reading procedure.
2. Erase DTC by WDS or equivalent.
3. Ensure that the customer’s concern has been resolved.

PID/Data Monitor and Record Procedure

1. Connect WDS or equivalent to the vehicle DLC-2 

16-pin connector.

2. Access and monitor PIDs by WDS or equivalent.

Active Command Modes Procedure

Note

• When driving, the ABS motor and each valve forcibly turn ABS_VOLT on, and then each command on. 

ABS_VOLT regulates the power supply for the ABS motor and 8 valves.

1. Connect WDS or equivalent to the vehicle DLC-2 

16-pin connector.

2. Turn the ignition switch to ON (Engine OFF) or 

start engine.

3. Activate active command modes using WDS or 

equivalent.
