Traction Control Enable
WARNING: This page is about a different car, the 1990 Cadillac Allante. However, it is still accessible from the selected car via links, so may be relevant.
The traction control enable line is used by the EBCM to monitor the BCM. The BCM will inform the EBCM to enable (the EBCM can control wheel slip, if needed) or disable traction control (the EBCM cannot control wheel slip).
