Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
ABS Telltale
The ABS telltale is turned on by the instrument cluster when it receives a command from BCM. The BCM receives telltale illumination information from the EBTCM through the Key Word 2000 (KW2000) data link. ABS telltale indicator is illuminated for about 3 seconds during engine start-up for a system check. If ABS telltale indicator remains on, a fault is detected in ABS system and ABS has been disabled. For additional ABS information, see appropriate ANTI-LOCK article in BRAKES.
