Circuit Description
Operation (ON/OFF) of ABS warning lamp is controlled by ABS control module through lamp driver module in
combination meter.
If the antilock brake system is in good condition, ABS control module turns ABS warning lamp ON at the ignition switch
ON, keeps it ON for 2 seconds and then turns it OFF. If an abnormality in the system is detected, ABS warning lamp is
turned ON continuously by ABS control module. Also, it is turned ON continuously by lamp driver module when the
connector of ABS control module is disconnected.

Scan Tool Data Definition
Battery Volt (V): Battery Voltage is an analog input
signal read by the ABS control module. Certain ABS
control module functions will be modified if the
battery voltage falls below or rises above
programmed thresholds.
Pump Motor Relay (V): This parameter indicates the
operational condition of the pump motor relay
(transistor).
RF Wheel Speed, LF Wheel Speed, RR Wheel Speed
and LF Wheel Speed (km/h, MPH): Wheel speed
is an ABS control module internal parameter. It is
computed by reference pulses from the wheel speed
sensor.
Brake Switch (ON, OFF): This switch signal informs
the ABS control module whether the brake is active
or not.
G Sensor (G): The G-Sensor converts gravity during
the vehicle acceleration / deceleration in to a voltage
conditions and controls the ABS for 4WD vehicle.
