Start the engine and watch for brake failure warning lamp. It should light for 2 seconds and then go out. If it lights constantly: Check the brake fluid level. Check whether any diagnostic trouble codes (DTCs) are stored in the ABS system:
1. The hydraulic braking system must be checked for leaks if the brake fluid level is too low.
2. Carry out fault-tracing for the fault symptom if the brake fluid level is OK.
