Ford E-150 RABS light illumination with no driving or stopping issues, additional concerns include heater not getting hot and brake pedal pulsation on Ford E-150

Some Ford E-150 owners report experiencing issues when the RABS light illuminates without noticeable driving or stopping problems, alongside concerns about the heater not getting hot and brake pedal pulsation. These owners suggest that the RABS control module may have an internal fault, necessitating replacement, and emphasize the need for a complex diagnosis to pinpoint the exact cause related to the RABS system. Additionally, the heater not getting hot could indicate a malfunctioning heater core, thermostat, or blend door actuator, prompting the need for inspection and potential replacement of these components. Furthermore, brake pedal pulsation may signal warped brake rotors or issues with the brake calipers, making it essential to inspect the entire brake system to identify and resolve the underlying cause. For effective resolution of these concerns, consulting a qualified mechanic or technician is highly recommended to ensure optimal performance and safety of the vehicle.
