3-Pin 1-936527-2 Headlight Height Adjustment Motor Connector – Hyundai / Kia

Direct-fit replacement for TE Connectivity / AMP part number 1-936527-2, the 3-pin waterproof 0.6mm connector used for headlight leveling (height adjustment) motor harnesses on Hyundai and Kia vehicles. This connector interfaces between the body control module (BCM) and the headlight leveling actuator motor mounted inside the headlight assembly.

Headlight Leveling System – How It Works

Hyundai/Kia automatic headlight leveling systems use a small stepper motor inside each headlight assembly to adjust the beam angle based on vehicle load. The 1-936527-2 connector carries three signals:

• Pin 1: Motor power supply (12V)
• Pin 2: Ground reference
• Pin 3: BCM control signal (PWM or stepped voltage)

Common Failure Symptoms

• Headlight beam fixed in one position – does not adjust with load changes
• Headlight leveling warning light on dashboard
• C1604 / C1605 – Headlight leveling actuator circuit fault (Hyundai GDS diagnostic)
• One headlight aimed too high or too low compared to the other
• Leveling motor making grinding noise but not moving – often caused by open circuit at connector, not motor failure

Frequently Asked Questions

Q: What is the mating male connector for 1-936527-2?
A: The mating male housing is 1-936526-2 (3-pin male, 0.6mm waterproof series). Both use the same 0.6mm sealed terminal.

Q: Can a bad connector cause the headlight leveling motor to fail?
A: Yes. An open circuit at the 1-936527-2 connector cuts power or signal to the leveling motor. The BCM detects the open circuit and logs a fault code. Always inspect and test the connector before replacing the leveling motor – the motor itself is significantly more expensive.

Q: What crimping tool is needed for 0.6mm terminals?
A: Use a precision micro-crimper rated for 0.3mm² (22 AWG) – such as the Engineer PA-09 or TE Connectivity 91516-1. Standard automotive crimpers will crush the 0.6mm terminal barrel.

Q: Is this connector compatible with aftermarket headlight assemblies?
A: Yes, provided the aftermarket assembly uses the same 3-pin 0.6mm leveling motor connector. Some aftermarket headlights use a different connector format – verify before ordering.
