ABS (Anti-lock Brake System)

The Antilock Brake System (ABS) telltale is turned ON by the cluster when it receives a command from the body control module (BCM). The BCM receives this information from the EBTCM through the Key Word 2000 data link.

The ABS telltale indicator lamp is turned ON, for approximately 3 seconds, during engine start-up for a visual system check.

If the telltale stays ON, it informs the driver that a problem has occurred and that the ABS system has been disabled. The vehicle should be taken in for service as soon as possible.
