Procedure
1. Turn the ignition switch OFF.
2. Connect the CONSULT-II connector to the vehicle-side data link connector.
3. Turn the ignition switch ON.
4. Touch “START” on the display.
5. Touch “ABS” on the display.
CAUTION:
Just after the engine is started, or the ignition switch is
turned ON, “ABS” may not be displayed on the system
selection screen even if “START” is touched. In this case,
start the self-diagnosis again from step 2.
6. Touch “DATA MONITOR”.
7. The data monitor item selection screen is displayed, and touch

TROUBLE DIAGNOSIS
●If a leak or oozing is detected on the ESP actuator body, wipe the applicable part with a clean cloth.
Then check again for leaks, and if there is still a leak or oozing, replace the ESP actuator body.
CAUTION:
Do not disassemble the actuator body.
3. Check the brake disc rotor and pads.
PRELIMINARY CHECK 2: (INSPECTION FOR LOOSE POWER SUPPLY TERMINAL)
Check the battery for looseness on the battery positive/negative terminals and ground connection. If loose-
ness is detected, tighten the piping to the specified torque. Check that the battery voltage does not drop and
the alternator is normal.
PRELIMINARY CHECK 3: (INSPECTION FOR ABS WARNING LAMP, ESP OFF INDICATOR
LAMP, AND SLIP INDICATOR LAMP)
1. Check that the ABS warning lamp is ON for Approx. 0.5 seconds when the ignition switch is turned ON. If
it does not turn on, check the ABS warning lamp and the circuit, and the combination meter.
2. Check that ESP OFF indicator lamp is ON for Approx. 0.5 seconds when the ignition switch is turned ON.
If it does not turn ON, check the ESP OFF indicator lamp and the circuit, and the combination meter.
3. Check that the SLIP indicator lamp is ON for Approx. 0.5 seconds when the ignition switch is turned ON. If
it does not turn ON, check the SLIP indicator lamp and the circuit.
4. With the engine running, check the ESP OFF indicator lamp turns ON and OFF when the ESP OFF
switch turns ON and OFF. If it dose not operate in accordance with the switch, check the ESP OFF switch
and the circuit.
5. Check that the ESP OFF indicator lamp turns OFF after Approx. 2 seconds delay when the ESP OFF
switch turned ON (The ESP/TCS system was not operated). If the ESP OFF indicator lamp does not turn
OFF in 10 seconds from the engine start, perform the self-diagnosis of ESP/TCS/ABS control unit.

Inspection procedure
1. SELF-DIAGNOSIS RESULT CHECK 1
Check the self-diagnosis results.
Are any self-diagnosis result items above indicated?
>> GO TO 2.
2. CHECK THE CONNECTOR
Remove connectors of the wheel sensor which is malfunctioning and the ESP/TCS/ABS control unit. Check
whether the deformation of terminal, or incorporate connection of connectors. Then, connect connectors. In
addition, check if the wheel sensor cable is damaged due to friction.
Does ABS warning lamp is out when driving 30 km/h (19 MPH) for Approx. One minute?
YES >> Check is completed.
NO >> GO TO 3.

1. Disconnect the ESP/TCS/ABS control unit connector.
2. Turn on the ignition switch and check the voltage between the
ESP/TCS/ABS control unit (vehicle-side connector B111) and
body ground.
Is inspection result OK?
YES >> Check the ESP/TCS/ABS control unit power supply circuit.
NO >> GO TO 4.
