ABS (Antilock Brake System)

The 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 electronic brake/traction control module (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.
