2-Pin 0.7mm Front Bumper Radar / Crash Sensor Connector OEM 54390242 / 13610095 – Kia K2 K3 K4 K5 / Buick LaCrosse / Chevrolet
Direct OEM-specification replacement for the 2-pin 0.7mm ultra-fine-pitch connector used on front bumper radar sensors and crash/impact sensors across Kia and GM (Buick/Chevrolet) platforms. Cross-references OEM numbers 54390242, 13610095, 31402-2110, and 31403-2110. The 0.7mm pitch is an ultra-fine-pitch design used for low-current radar signal circuits — the connector is located in the front bumper area and is susceptible to damage from minor impacts, pressure washing, and moisture ingress through bumper gaps.

Q: My forward collision warning (FCW) is disabled after a minor bumper impact — could it be the connector?
A: Yes. A minor front bumper impact frequently damages the 2-pin radar sensor connector without visibly damaging the bumper or sensor itself. The 0.7mm ultra-fine-pitch connector is particularly vulnerable to impact damage — even a slight deformation of the housing can cause intermittent or permanent signal loss. Inspect the connector before replacing the radar sensor ($200–$800).
Q: What is the difference between 54390242 and 13610095?
A: 54390242 is the primary Kia OEM part number; 13610095 is the GM (Buick/Chevrolet) cross-reference for the same connector. Both refer to the identical housing — the different numbers reflect different OEM catalog systems for the same physical part.
Q: Are terminals included?
A: Yes, 0.7mm ultra-fine-pitch terminals are included with all variants.
