WARNING LIGHT INDICATORS
The Anti-Lock Brake System (ABS) uses an Amber ABS warning light to alert driver that ABS function has been disabled. Normal power assisted braking remains functional, but wheels can lock during a panic stop if Amber ABS warning light is on. There are 3 conditions which will illuminate ABS warning light: ABS system malfunction.
Low brake fluid level detected by Anti-Lock Brake Control Module (ABCM). Red BRAKE warning light will also be illuminated.
Wiring problem in low brake fluid level detection circuit. Red BRAKE warning light will also be illuminated.
If ABCM detects that Amber ABS warning light cannot be illuminated, Red BRAKE warning light will be illuminated in its place and Diagnostic Trouble Code (DTC) C1220 will be stored in memory.
