Circuit Description
WARNING: This page is about a different car, the 2002 Buick Regal and 2002 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.
The Low Traction indicator is controlled by the instrument cluster via serial data messages from the EBCM. When the ABS or TCS is active for 0.5 seconds, the EBCM commands the instrument cluster to turn ON the Low Traction indicator.
The Low Traction indicator will also turn ON during the instrument cluster bulb check. When the ignition switch is turned to ON, the Low Traction indicator will turn ON for approximately 3 seconds and then turn OFF.
