Diagnostic Notes

DESCRIPTION
The yellow rear ABS warning light will automatically begin a flash-out sequence if the diagnostic line Circuit 571 or 483 is shorted to ground. This will result in a blown fuse for the Keep Alive Memory Power for the RABS II Module. An open Keep Alive Memory (KAM) fuse is most likely caused by a grounded diagnostic connector.
