ESC hydraulic control system
4.3-22
Calibration of lateral acceleration and
longitudinal acceleration sensors
1 - Protection
Place protective pads at following locations:
Front fender;
Front bumper;
Driver’s seat;
Carpet (on driver's side);
Steering wheel;
Parking brake lever;
Shift lever.
2 - Operations
CAUTION
It is necessary to calibrate the lateral
acceleration and longitudinal acceleration
sensors after the ESC hydraulic control unit
is replaced.
It is necessary correctly refit the ESC
hydraulic control unit and calibrate the lateral
acceleration and longitudinal acceleration
sensors if the ESC hydraulic control unit has
been removed or replaced. If the installation
location is not correct, the sensor cannot be
successfully calibrated. In order to avoid
large calibration error of the lateral
acceleration sensor caused by the left and
right tilt of the vehicle, large calibration error
of the longitudinal acceleration sensor
caused by the front and rear pitch of the
vehicle, it is recommended to complete the
calibration on the four-wheel alignment
bench.
Do not step on the brake pedal during the
calibration of the sensors to prevent the
calibration error of the pressure sensor from
being above the standard value.
