Hyundai Genesis Coupe Head Lamps Wiring Diagram SD921-2 - HID & Non-HID
Wiring diagram of the headlamp system showing control modules and the high and low beam head lamp circuits.
This document is page SD921-2, titled "Head Lamps (2)," a factory-style wiring diagram covering the head lamp circuits. Power originates from the E/R (engine room) Junction Box LH through a multi fuse with two 60A elements (B+3 and B+2), feeding the Smart Junction Box via 5.0R and 5.0L wires (referencing Power Distribution page SD110-7). Inside the Smart Junction Box, the IPS Control Module drives ARISU 1 and ARISU 2 outputs (ARISU 1 Control, Battery Power, Ground (HID), ARISU 2 Control). Outputs run to the left head lamp (connector E95) and right head lamp (connector E96), each with HI and LO beam bulbs. Wire gauges and colors differ by equipment: 1.25W or 1.25P with HID vs. 0.5P/0.85P without HID for low beams, and 0.5R/0.85R for high beams. Ground wires (0.5B, 1.25B/0.5B, 2.0B, 0.85B) route through connector EE11 pin 21 to ground points GE03 and GE05, with a cross-reference to Ground Distribution page SD130-4. Photo references (PHOTO 1, 2, 5, 44, 49) locate components. The diagram gives pin numbers for the SJB (pins 30, 20, 23, 27, 37, 19, 1) and lamp connectors, useful for diagnosing headlight power, HID vs. non-HID wiring, and ground faults.

Frequently asked questions
- What fuses power the head lamp circuits in this diagram?
- Two 60A multi fuse elements in the E/R Junction Box LH, labeled B+3 (60A) and B+2 (60A), which are hot at all times and feed the Smart Junction Box.
- Which connectors serve the left and right head lamps?
- The left head lamp (HEAD LAMP LH) uses connector E95 (pins 1, 2, 5, 6) and the right head lamp (HEAD LAMP RH) uses connector E96 (pins 1, 2, 5, 6).
- How do the wire sizes differ between HID and non-HID equipped vehicles?
- For the low beam feeds, vehicles with HID use 1.25W (LH) and 1.25P (RH) wires, while non-HID vehicles use 0.5P and 0.85P. The LH ground is 1.25B with HID and 0.5B without HID.
- Where do the head lamp ground wires terminate?
- Grounds route via 2.0B wire through EE11 pin 21 to ground point GE03 (PHOTO 2), with the SJB HID ground (0.3B on pin 23) going to GE05 (PHOTO 44). Ground distribution is detailed on SD130-4.
- What module controls the head lamp outputs?
- The IPS Control Module inside the Smart Junction Box controls ARISU 1 and ARISU 2 outputs (ARISU 1 Control, Battery Power, Ground (HID), ARISU 2 Control) that drive the head lamps.
