- Do both the red brake and yellow RABS lamps come on?

YES -- Hard fault. Go to 12.2. 12.2

NO -- If the brakes have been serviced recently, or if brake fluid has been added to the system recently, most likely, the Code 12 was falsely set at that time and the RABS is OK. If this is not the case, go to Pinpoint Test ID for Intermittent Diagnosis Procedures for the affected circuits. Intermittent Diagnosis Procedure

NO -- Refer to the system schematic for this pinpoint test. If yellow RABS lamp is ON and Code 12 is present, service open circuit on pin 2, circuit 512 (T/LG).
