Anti-lock Light Ground (Main Relay)

WARNING: This page is about a different car, the 1988 Buick Riviera and 1988 Buick Reatta. However, it is still accessible from the selected car via links, so may be relevant.

When main relay is not enabled by EBCM, ANTI-LOCK light is grounded through diode and circuits No. 852, 850 and 150 at main relay to body ground. This will cause the ANTI-LOCK light to be on any time main relay is disabled. When main relay is enabled, path to ground is broken allowing ANTI-LOCK light to turn off.
