Communication with Hi-scan (pro) is not
possible.
(Communication with any system is not possible)

1. Power source circuit

2. Diagnosis line

BR - 63

Communication with Hi-scan (pro) is not
possible.
(Communication with ABS only is not possible)

1. Power source circuit

2. Diagnosis line

3. HECU

BR - 63

When ignition key is turned ON (engine OFF),
the ABS warning lamp does not light up.

1. ABS warning lamp circuit

2. HECU

BR - 64

Even after the engine is started, the ABS
warning lamp remains ON.

1. ABS warning lamp circuit

2. HECU

BR - 65

ABS does not operate.

Only when 1. -4. are all normal and the problem
is still occurring, replace the HECU.

1. Check the DTC reconfirming that the normal

code is output.

2. Power source circuit.

BR - 66

3. Wheel speed sensor circuit.

4. Check the hydraulic circuit for leakage.

During ABS operation, the brake pedal may vibrate or may not be able to be depressed. Such phenomena are due to
intermittent changes in hydraulic pressure inside the brake line to prevent the wheels from locking and is not an
abnormality.

FAILSAFE SPECIFICATION

DETECT MODE

THE ABILITY OF DETECTING A FAILURE

THE MANAGEMENT OF FAILURE DETECTION

1. System down. Both the ABS (TCS) and the EBD function are inhibited and the ABS (TCS) and the EBD warning lamps are

activated.

If this happens, the valve relay and all solenoids are prevented from being switched on.

2. Only the ABS (TCS) function is inhibited. The ABS (TCS) warning lamp is activated and the EBD warning lamp is not

activated.

3. Sensor failure outside the ABS control cycle.

(1) Only one sensor fails: take the same action as management 2.

(2) More than two sensors fail: take the same action as management 1.

4. Sensor failure inside the ABS control cycle.

(1) One front sensor fails: inhibit the ABS control of the failed-wheel and maintain ABS control of the normal wheels.

After the controller completes the ABS control, take the same action as in management 2.

(2) One rear sensor fails: inhibit ABS control of both front wheels and the pressure of both rear wheels is decreased.

After the controller completes the ABS control, take the same action as in management 2.

(3) More than two sensor fail: take the same action as in management 1.

5. Low operating voltage

(1) Outside the ABS control cycle: inhibit the ABS (TCS) control of front wheels and allow ABS control of rear wheels,

deactivating the motor.
The ABS (TCS) warning lamp is directly switched on.
When the voltage recovers to the normal operating range, enable the ABS function and the ABS (TCS) warning lamp
is switched off and erases the error code of low voltage.

(2) Inside the ABS control cycle: inhibit the ABS control of the front wheels and allow the the ABS control of rear wheels,

deactivating the motor.
The ABS (TCS) warning lamp is directly switched on and remains on. The error code is always stored.

6. Motor error during the ABS control cycle. Inhibit the ABS control of front wheels, allow ABS control of the rear wheels and

ABS (TCS) warning lamp is switched ON at the end of ABS control.

7. TCS failure

Inhibit the TCS control and allow the ABS/EBD control. Meanwhile, stop checking the TCS switch failure under the TCS
control.
