DESCRIPTION
The amber ABS warning lamp and red warning lamp are located in the instrument cluster. The amber ABS warning lamp illuminates at start-up to
perform a self check. The lamp goes out when the self check program determines the system is operating normal. The red brake warning lamp is used
to alert the driver of a hydraulic fault or that the parking brake is applied.
