1. Stop vehicle with front wheels in straight-ahead position.
CAUTION:

The work should be done at a horizontal place when vehicle is in the unloaded vehicle condi-
tion.

Keep all tires inflated to correct pressures. Adjust the tire pressure to the specified pressure
value.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data link connector on vehicle, and turn ignition switch ON (do not start engine).
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which performs CAN communication.
3. Touch “ABS”, “WORK SUPPORT” and “DECEL G-SEN CALIBRATION” on CONSULT-II screen in this order. Refer to BRC-26, "
CONSULT-II BASIC OPERATION PROCEDURE" .
4. Touch “START”. CAUTION:
Set vehicle as shown in the display.
5. After approximately 10 seconds, touch “END”. (After approxi- mately 60 seconds, it ends automatically.)
6. Turn ignition switch OFF, then turn it ON again. CAUTION:
Be sure to perform above operation.
7. Run vehicle with front wheels in straight-ahead position, then stop.
8. Select “DATA MONITOR”, “SELECTION FROM MENU”, and “DECEL G-SEN” on CONSULT-II screen. Then make sure “DECEL G-SEN” is within 0 ±0.08 G. If value is
more than specification, repeat steps 3 to 7.
9. Erase memory of ABS actuator and electric unit (control unit) and ECM.
10. Turn ignition switch OFF.
