Problem overview

Some Mazda B3000 owners report experiencing issues when both the ABS and brake lights are illuminated while the turn signals are not functioning. This situation may indicate a fault in the ABS system, often linked to a faulty wheel speed sensor or a malfunctioning sensor within the ABS system itself. Additionally, the ABS light could suggest a problem with the speed sensor near the transmission, which is vital for the ABS's activation based on speed input. Furthermore, the failure of the turn signals may stem from electrical issues, such as a faulty turn signal relay or wiring problems. It is crucial for owners to address these concerns promptly to maintain vehicle safety and functionality, and they may need to seek help from a qualified mechanic or dealership if troubleshooting proves difficult.
