What is the reason for the simultaneous illumination of the ABS and airbag lights in the Ford Escort?

There are two reasons for the simultaneous illumination of the ABS and airbag lights in the Ford Escort: one is the excessive gap in the copper piece of the front wheel sensor plug, and the other is due to cable breakage. Information related to ABS and airbags: 1. How ABS works: The sensor installed on the wheel sends a signal that the wheel is about to lock up. The controller then instructs the regulator to reduce the oil pressure in the wheel's brake cylinder, decreasing the braking torque. After a certain period, the original oil pressure is restored. This cycle repeats continuously (up to 5~10 times per second), keeping the wheel in a rotating state while maintaining maximum braking torque. 2. How airbags work: Airbags are inflatable soft bags installed in vehicles that deploy instantly during a collision to provide cushioning, protecting the safety of the driver and passengers.
I've encountered a situation where both the ABS and airbag lights illuminate simultaneously on a Ford Escort, which often indicates an issue with a shared system. For example, if the power supply fuse blows, both lights rely on the same circuit, triggering an alarm once the fuse is blown. Another common cause is wiring faults, such as loose or shorted ground wires, especially prone when there's excessive water accumulation under the car. It could also be due to sensor failures, like a faulty wheel speed sensor, affecting the ABS and falsely reporting an airbag fault. On the Ford Escort forums, module communication errors are also cited as a cause. I recommend first checking the fuse box yourself to locate the relevant fuse (its position is in the user manual). If the fuse isn't blown, try tightening the ground bolt. If the issue persists, use an OBD scanner to read the fault codes—don't delay, as driving with a malfunctioning airbag is extremely dangerous.
Last time when my car's ABS and airbag lights came on simultaneously, my heart was in my throat. This usually indicates a vulnerability in the overall safety system. In the Ford Escort's design, the ABS and airbag share some control units, so a blown fuse is the prime suspect. Older vehicles with aging wiring harnesses are more prone to short circuits, or intermittent alarms caused by loose connectors. I tried restarting by disconnecting the power—sometimes the lights went off, but the issue remained unresolved, making it only a temporary fix. Considering that an illuminated airbag light means collision protection failure, it must be addressed promptly. I recommend seeking professional repair to diagnose the root cause using a scan tool to read fault codes. Make it a habit to check warning lights before daily drives to avoid unexpected surprises.
Simultaneous illumination of the ABS and airbag warning lights is not uncommon in the Ford Escort, often stemming from power supply or sensor issues. A blown fuse is an easy diagnostic point that you can replace yourself. Poor grounding is also common, especially when chassis moisture causes short circuits. If the lights flash before staying on, it might indicate dirty wheel speed sensors interfering with ABS and triggering false airbag alerts. I've encountered cases where restarting the vehicle temporarily turned off the lights, suggesting a software glitch requiring ECU firmware updates. Never ignore these warnings - airbag malfunctions can be life-threatening. Visit a repair shop immediately to eliminate potential hazards.
