Swift GA L4-1298cc 1.3L SOHC MFI (2001)
Brake Warning Indicator: Description and Operation
Brake Warning Light
The red "BRAKE" warning light will be illuminated when a low brake fluid level in the master cylinder is sensed, the parking brake switch is closed
(parking brake engaged), the ignition switch is in "ON" and the engine is not running or under control of the EBCM when certain ABS DTCs are set.
This indicates to the driver a base brake problem may exist.
ABS ACTIVE Light
The blue "ABS ACTIVE" light identifies when the system is working to provide antilock braking.
INDICATOR LIGHT OPERATION
The ABS uses three lights, the amber ABS warning light, a blue ABS ACTIVE light and a red BRAKE warning light.
Normal Indicator Light Operation
NOTE: When performing the above check, be sure to release the parking brake and apply wheel stoppers to the tires, or the BRAKE warning light
will stay ON.
INITIALIZATION
During initialization, the EBCM will not only perform self-diagnostics, but will also verify motor, modulator, solenoid, relay and indicator light
operation to ensure all components are functioning properly. If the EBCM detects a malfunction in either itself or other ABS components, it will store
a Diagnostic Trouble Code (DTC) and illuminate the "ABS" warning light if applicable.
The "ABS" and "ABS ACTIVE" warning lights will be illuminated for about three seconds when the ignition switch is first turned to "ON." A slight
mechanical noise may be heard during system initialization. This is a normal occurrence-it is the result of the hydraulic modulator pistons returning to
their upmost (or home) position. System initialization will occur when the vehicle speed reaches approximately 5 km/h (3 mph). If the driver has
their foot on the brake pedal during system initialization, they may feel a slight pedal bump. When this occurs, system initialization is interrupted.
