2010 Hyundai Genesis Coupe PDM Wiring Diagram (2) SD952-6 - Start Stop Button
Wiring diagram of the Power Distribution Module covering the smart key control module, start-stop button and immobilizer circuits.
This document is page SD952-6 of a Hyundai wiring diagram set, showing sheet 2 of the Power Distribution Module (PDM) circuit. It illustrates hot-at-all-times power feeds from the I/P Junction Box through three fuses — ESCL (PDM-A) 25A, ESCL (PDM-B) 10A, and ESCL SW 10A — with cross-references to Power Distribution (SD110-7), Passenger Compartment Fuse Details (SD120-1), and Illuminations (SD941-2). The diagram details wiring between the Smart Key Control Module (connector M14-A, pin 23), the BCM (connector M02-A, pin 24), the Start Stop Button Switch (connector M57, pins 1–9, including illumination power/ground, amber and green indicator LEDs, and SSB SW-1/SW-2 signals), and the Fob Holder (connector M26, pins 2–8, including illumination, immobilizer Data/Clock lines, Key-In switch, and ground at GM02). All of these circuits terminate at the PDM (connectors M51-A/M51-B) with labeled internal functions: BATT-LOAD, BATT-CPU, SSB illumination power, LS drivers, logic input, immobilizer data/clock, FOB IN, and the Main MCU. Wire colors (R, W, Gr, P, P/B, R/B, R/O, B, Y, G, L, B/O, O) are marked on every run, and photo references (49, 52, 59, 60, 62, 63, 71) point to connector location photos. Useful for diagnosing push-button start, smart key, fob holder, and immobilizer issues.

Frequently asked questions
- What fuses power the Power Distribution Module circuits on this diagram?
- Three fuses in the I/P Junction Box, all hot at all times: ESCL (PDM-A) 25A, ESCL (PDM-B) 10A, and ESCL SW 10A.
- What connector does the Start Stop Button Switch use and what are its pins?
- Connector M57: pin 9 ILL.(-) (Gr), pin 7 SSB SW-2 (P), pin 2 B+(ILL.+) (P), pin 6 B+ (R/B), pin 5 ILL. PWR (P), pin 4 ILL. GND (B), pin 3 AMBER (Y), pin 8 GREEN (G), and pin 1 SSB SW-1 (L).
- How is the Fob Holder wired to the PDM?
- Via connector M26: pin 8 ILL.(+) and pin 6 B+ (both R/O wires from the I/P junction box), pin 4 ILL.(-) (B/O), pin 7 IMMO Data (L), pin 3 IMMO Clock (O), pin 2 KEY IN SW (R), and pin 5 Ground (B) to ground point GM02.
- Which other wiring diagram pages does this sheet reference?
- It references Power Distribution (SD110-7), Passenger Compartment Fuse Details (SD120-1), and Illuminations (SD941-2), plus photo references 49, 52, 59, 60, 62, 63, and 71.
- Where do the Smart Key Control Module and BCM connect on this circuit?
- The Smart Key Control Module connects to SSB SW-2 at connector M14-A pin 23 (wire P), and the BCM connects to SSB SW-2 at connector M02-A pin 24 (wire P/B).
