Hyundai Genesis Coupe Data Link Connector (OBD-II) Wiring Diagram SD200-1
Data link wiring diagram showing the 16-pin data link connector, CAN-high/low buses, and connections to BCM, TCM, and control modules.
This is page SD200-1, "Data Link Details (1)," a factory wiring diagram showing the Data Link Connector (DLC/OBD-II connector, connector M50) circuit and its 16-pin pinout. Labeled pins include: 1 Chassis K-Line, 2 P/T K-Line, 3 CAN-High, 4 Ground, 5 Ground, 6 Vehicle Speed, 9 Memory Power, 11 CAN-Low, 12 Code Save, and 13 Body K-Line. The diagram traces wiring between the DLC and numerous modules: TCM (with G6DA and G4KF engine/transmission variants), instrument cluster, A/C control module, audio unit, BCM, smart key control module, SRS control module, tire pressure monitoring module, auto head lamp leveling device sensor, and vehicle speed sensor. Power comes from the I/P Junction Box via the 7.5A AUTO SHIFT LOCK fuse (hot at all times), with a 122Ω terminating resistor shown, referencing Power Distribution SD110-7 and fuse details SD120-2. Grounds route through joint connectors JM01/JM03/JM04/JM06 to grounds GM02 and GM03 (Ground Distribution SD130-2). Wire colors noted include Y (yellow), W (white), L (blue), R (red), B (black), O (orange), B/O, Gr/O, G, and P/B. Continuation references point to SD200-2, SD200-3, and SD200-4, plus numerous connector photo references (PHOTO 39–95).

Frequently asked questions
- What is the pinout of the Data Link Connector shown in this diagram?
- Connector M50: pin 1 Chassis K-Line, pin 2 P/T K-Line, pin 3 CAN-High, pin 4 Ground, pin 5 Ground, pin 6 Vehicle Speed, pin 9 Memory Power, pin 11 CAN-Low, pin 12 Code Save, pin 13 Body K-Line; pins 7, 8, 10, 14, 15, 16 are unlabeled.
- What fuse powers the Data Link Connector's memory power circuit?
- The 7.5A AUTO SHIFT LOCK fuse in the I/P Junction Box, which is hot at all times (see Power Distribution SD110-7 and passenger compartment fuse details SD120-2).
- Which modules connect to the DLC's K-Line circuits?
- The TCM (P/T K-Line via connectors CLG-ZF pin 3 for G6DA or CHG-T pin 20 for G4KF), the A/C control module and auto head lamp leveling device sensor on Body K-Line, the BCM (M02-A/M02-C), audio, and the smart key control module (DIAG K, pin 22 M14-A).
- Where do the DLC ground pins go?
- Pins 4 and 5 route through joint connector JM01 to grounds GM03 (PHOTO 63) and GM02 (PHOTO 52), per Ground Distribution SD130-2.
- Which modules are on the CAN High/Low lines in this diagram?
- The SRS control module (M71-A pins 19 High / 20 Low), the instrument cluster (M11-B pins 9/10), and the tire pressure monitoring module (M69), connected through joint connectors JM03 and JM06.
