Scan Tool Data - Suzuki GRAND VITARA JB416 Service Manual

Scan Tool Data

The parameter data below are values measured with the scan tool when the normally operating vehicle is under the
following conditions. When taking measurements for comparison by using the scan tool, be sure to check that the
vehicle is under the following conditions.
• Apply parking brake and block wheels.
• Ignition switch ON.
• Turn OFF air conditioning (if equipped).
• Set the wheel in straight-ahead position and hands off steering wheel.
• Turn OFF all electric loads (except ignition).
• Check that there is no DTC.

Scan Tool Data Definition
Battery Volt (V): Battery Voltage is an analog input
signal read by the ESP® control module. Certain
ESP® control module functions will be modified if the
battery voltage falls below or rises above
programmed thresholds.
Pump Motor Driver (V): This parameter indicates the
operational condition of the pump motor driver
(transistor).
RF Wheel Speed, LF Wheel Speed, RR Wheel Speed
and LR Wheel Speed (km/h, MPH): Wheel speed
is ESP® control module internal parameter. It is
computed by reference pulses from the wheel speed
sensor.
Brake Switch (ON, OFF): This switch signal informs
the ESP® control module whether the brake is active
or not.
G Sensor (G): Vehicle acceleration is measured by yaw
rate / G sensor assembly and output to ESP®
control module by pulse signal for 4WD vehicle.
Master Cyl Press (MPa): Brake fluid pressure from
brake master cylinder.
