Detailed Description

Delphi SS21674 is engineered for vehicles that rely on precise wheel speed data to support ABS operation and related brake control functions. Delphi validates its sensors through OE-focused development and calibration methods, helping deliver consistent signal quality and reduce repeat repairs. This front left sensor is a strong match for drivers and technicians servicing Cadillac XT5 and GMC Acadia brake sensor applications.

This part cross-references Standard Ignition ALS3122 for the same application.

What It Helps Address

• ABS warning light caused by a failed front left wheel speed sensor
• Erratic or missing wheel speed signal at the brake control module
• Loss of anti-lock brake function from sensor circuit faults
• Brake system fault codes related to the front left wheel speed input
• Intermittent traction or stability control warnings tied to wheel speed data

Installation Notes and Tips

Verify connector style, harness routing, and mounting location before installation. This sensor uses a black square male connector with a 2-terminal layout and includes a wiring harness. Confirm front left placement on the vehicle and inspect the tone ring, hub area, and wiring path for damage or contamination before final assembly.

Quality Assurance

Delphi backs this sensor with OE development and validation practices, and each unit is tested and calibrated to OE standards for accurate readings. Compatible with 2018-2024 Cadillac XT5, front left, and 2018-2023 GMC Acadia, front left. Delphi SS21674 supports precise ABS wheel speed signal delivery for these applications.
