Are You Experiencing ABS Trouble Code Issues?
Prevent ABS Trouble Codes with PTC Hub Assemblies
If you’re seeing erratic ABS behavior or trouble codes after replacing a hub assembly, the culprit might be the tone ring quality. Many competitive hubs use cheap “pot metal” tone rings with rounded teeth that fail to generate accurate wheel speed sensor (WSS) signals—leading to ABS faults, poor braking performance, and even potential safety issues.
The Problem with Inferior Tone Rings
Most modern vehicles rely on a tone ring integrated into the hub assembly to send wheel speed signals to the ABS module. These signals must be precise. If the tone ring teeth are uneven or poorly shaped, the signal becomes erratic. On an oscilloscope, it should look like a consistent sine wave—but inferior rings can produce distorted waveforms that cause ABS errors or malfunction.
PTC’s OE-Style Solution
PTC Hub Assemblies are built with premium casted metal tone rings that feature rectangular teeth matching OE specs. These ensure a consistent, accurate pulse signal to the ABS module and eliminate the common issues caused by lower-grade components.
Why It Matters:
- Accurate WSS signals prevent ABS faults and false code triggers
- Prevents braking issues during high-speed operation
- Protects against unsafe driving conditions caused by ABS lockup
Don’t compromise on safety—choose PTC hub assemblies with OE-spec tone rings for reliable ABS performance.
