Detailed Description

Delphi SS21536 is an ABS wheel speed sensor engineered for rear left fitment on Mercedes-Benz GLC300, GLC43 AMG, and GLC350e applications. Delphi validates its vehicle sensors to OE standards, helping maintain consistent wheel speed data for the ABS system and related stability functions. The sensor uses a pin terminal design, includes one connector, and comes with a 672-length wiring harness for the specified application.

This part cross-references 253 905 25 00 for the same application. Use Delphi SS21536 when replacing a failed rear left wheel speed sensor on compatible Mercedes-Benz GLC models.

What It Helps Address

• ABS warning light caused by a faulty rear wheel speed sensor
• Erratic or missing wheel speed signal data
• Traction control or stability system fault codes tied to wheel speed input
• Brake system communication issues related to sensor output
• Intermittent sensor readings from worn or damaged wiring

Installation Notes and Tips

Confirm rear left placement before installation and match the connector style, terminal count, and harness routing to the original part. Inspect the mounting area and wiring path for damage, corrosion, or debris before connecting the new sensor. Delphi SS21536 is supplied without mounting hardware, so reuse or source any required fasteners separately if needed.

Quality Assurance

Delphi sensors are developed and validated using OE-focused methods and calibrated to OE standards for accurate signal output. That testing process supports dependable replacement performance on the specified Mercedes-Benz GLC applications.
