The anti-lock brake system (ABS) warning light in a Pontiac Vibe is controlled by a separate computer that is dedicated to the ABS system. When the ABS computer senses a problem with the ABS system, it stores a trouble code in its memory and illuminates the ABS warning light. In addition to illuminating the ABS warning light, the ABS computer also deactivates the ABS system to ensure the safety of the vehicle's occupants. The ABS warning light must be turned off using an automotive scan tool.
Turn the ignition to the "off" position and shift the transmission into park. Engage the emergency brake.
Plug the scan tool's data connector into the Vibe's diagnostic data port, located underneath the dashboard on the driver's side.
Power on the scan tool and select the "ABS" menu. Select "clear all codes."
Unplug the scan tool from the data port. Start the engine and verify that the ABS light is no longer illuminated.
Automotive scan tools are small computer units that are designed to connect to the vehicle's computer system through a diagnostic data port. They are used for performing diagnostic functions and running specific tests. Scan tools are available from auto parts stores and automotive tool manufacturers.
