ABS Light: Description and Operation

AMBER ABS WARNING LAMP
The amber ABS warning lamp is located in the instrument cluster. The purpose of the warning lamp is discussed in detail below.
When the ignition key is turned to the ON position, the amber ABS warning lamp is lit until the CAB completes its self-tests and turns off the lamp (approximately 4 seconds). The amber ABS warning lamp will illuminate when the CAB detects a condition that results in the shutdown of ABS function. The CAB sends a message to the mechanical instrument cluster (MIC) instructing it to turn on the amber ABS warning lamp.
Under most conditions, when the amber ABS warning lamp is on, only the ABS function of the brake system is affected; The electronic brake distribution (EBD), the base brake system and the ability to stop the vehicle are not affected.
