Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Abs And Brake Warning Indicators
The amber ABS warning indicator is located in the instrument cluster. It is used to inform the driver that the antilock function has been turned off. The ABS warning indicator is controlled by the CAB/ABM. The CAB/ABM controls the lamp with a command over the PCI bus.
The ABS Warning Indicator will remain lit during every key cycle until a circuit or component fault is repaired and the CAB/ABM no longer detects the fault. After repair of a sensor signal fault or a pump motor fault, the CAB/ABM must sense all four wheels at 25 km/h (15 MPH) before it will extinguish the ABS and TCS Indicator.
The Instrument Cluster will illuminate the ABS Warning Indicator if it loses communication with the CAB/ABM.
The red BRAKE warning indicator is also located in the instrument cluster. It can be activated in several ways. Application of the parking brake or a low fluid signal from the fluid level switch located in the master cylinder reservoir will cause the indicator to come on.
