- The second step in diagnosis of any anti-lock brake system condition is determination of the warning light behavior. The system uses 2 warning lights, the Red "BRAKE" warning light and an Amber "ANTI-LOCK" light.
- By observing when these lights come on, specific components and sub-systems of the brake system may be isolated as likely causes of a system malfunction.
- Each light sequence illustration is divided into 7 areas which represent vehicle status, with behavior of "BRAKE" and "ANTI-LOCK" lights represented in horizontal rows below vehicle status headers. See Fig 1 .
- "BRAKE" and "ANTI-LOCK" light status is indicated by shaded areas in horizontal rows below each vehicle status header. A vehicle status block which is not entirely shaded means that light is on only for part of the test period.
