Tesla has released Service Bulletin SB-24-33-006 R1, a campaign bulletin for 2024 Model 3 vehicles. This bulletin addresses a specific condition where the RH front Wheel Speed Sensor (WSS) harness might be misrouted, which could lead to damage to the harness. This issue, a Tesla Model 3 WSS misrouted condition, is considered non-safety-related and outlines the necessary inspection and repair procedures.

Why This Matters

While this is a non-safety-related condition, a damaged Wheel Speed Sensor harness can affect vehicle systems that rely on accurate wheel speed data. This campaign bulletin ensures that the Tesla Model 3 WSS misrouted issue is identified and corrected, preventing potential future problems with the vehicle's braking or stability control systems.

Symptoms

The primary symptom of this condition is a misrouted RH front Wheel Speed Sensor (WSS) harness. If the harness is misrouted, it may sustain damage. Owners might not notice an immediate symptom, but technicians will inspect for visible signs of damage to the WSS harness.

Diagnosis / Trigger Conditions

Technicians will inspect the RH front Wheel Speed Sensor (WSS) harness for any indications of damage. This includes checking the routing and ensuring that the three harness clips are properly installed and secured. The inspection process involves removing the RH front wheel assembly to gain access to the WSS harness.
