ABS ON-BOARD DIAGNOSTIC

A3U040243000W02

On-Board Diagnostic (OBD) Test Description

The OBD test inspects the integrity and function of the ABS and outputs the results when requested by the 
specific tests.

On-board diagnostic test also:
— Provides a quick inspection of the ABS.
— Is 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 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 SST (WDS or equivalent).

DTCs Retrieving Procedure
Using SST (WDS or equivalent)

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

16-pin connector located the left side of the 
steering column.

2. Retrieve DTC by WDS or equivalent.

Without using SST (WDS or equivalent)

Caution

••••

Connecting the wrong DLC terminal may possibly cause a malfunction. Carefully connect the 
specified terminal only.

1. Connect the TBS terminal at DLC to body ground 

using a jumper wire.

2. Turn the ignition key to ON (engine OFF).

3. After the ABS warning light illuminates for 3 sec

the ABS warning light indicates DTCs.

4. After completion of repairs, clear DTCs.

DTCs Clearing Procedure
Using SST (WDS or equivalent)

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

Note

After repairing the ABS wheel-speed sensor or replacing ABS HU/CM, the ABS and/or BRAKE system 
warning light may not go off when ignition key is turned ON. In this case, start engine and drive the vehicle 
at a speed of more than 10 km/h {6.2 mph} until the ABS and/or BRAKE system warning light goes off.

Without using SST (WDS or equivalent)

Caution

••••

Connecting the wrong DLC terminal may possibly cause a malfunction. Carefully connect the 
specified terminal only.

1. Connect the TBS terminal at the DLC to body 

ground using a jumper wire.

2. Turn the ignition key to ON (engine OFF).
3. Output all stored DTCs.
4. After verifying that the first code is repeated, 

depress the brake pedal 10 times at intervals of 
less than 1 second.

5. Turn the ignition key to OFF and disconnect the 

jumper wire.

6. Turn the ignition key to ON and verify the ABS 

warning light turns off after 3 seconds.

Note

DTCs cannot be cleared if the following 
conditions occur:
— If intervals of depressing the brake pedal exceed 1 second.
— The brake switch has failed.

After repairing the ABS wheel-speed sensor or replacing ABS HU/CM, the ABS and/or BRAKE system 
warning light may not go off when ignition key is turned ON. In this case, start engine and drive the vehicle 
at a speed of more than 10 km/h {6.2 mph} until the ABS and/or BRAKE system warning light goes off.

PID/Data Monitor and Record Procedure

1. Connect WDS or equivalent to the vehicle DLC-2 16-pin connector located the left side of the steering column.
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_POWER on, and then each command on. 
ABS_POWER regulates the power supply for the ABS motor and 8 valves.

1. Connect WDS or equivalent to the vehicle DLC-2 16-pin connector located the left side of the steering column.
2. Turn the ignition key to ON (Engine OFF) or start engine.
3. Activate active command modes by WDS or equivalent.
