This document is page 6 of the Multiport Fuel Injection (MFI) Control System wiring diagram, sheet SD313-14, for the Hyundai G6DA-GSL 3.8L engine (Genesis Coupe BK1). It shows power feeds from the I/P Junction Box: the CLUSTER/ESCL 7.5A fuse (hot in ON or START) and the MEMORY 10A fuse (hot at all times), with references to Power Distribution pages SD110-7/8/9 and passenger compartment fuse details SD120-2/SD120-3. The diagram traces circuits to the instrument cluster (PHOTO 51), including the CRUISE, CRUISE SET, CHECK ENGINE, and IMMO indicator lamps driven through the cluster MICOM, and a branch to the cruise remocon switch (SD313-13). CAN High and Low lines route through joint connectors JABAG, JM03, JM06, JE67, MF11, and EF11 (with data-link detail references SD200-1 and SD200-3) to ECM pins 10 (CAN High) and 35 (CAN Low). Other ECM connections shown are pin 25 Engine Check indicator (Br/B), pin 4 Immobilizer MIL (G), and pin 74 ELG-A IMMO signal (Y). Immobilizer signals split between the Smart Key Control Module M14-A (with button start) and Immobilizer Module M36 (without button start). Connector photo references and wire colors (R, L, P, Y, Y/B, Br/B, G) are labeled throughout.

Frequently asked questions

Which fuses power the MFI control/instrument cluster circuits on this diagram?
The CLUSTER/ESCL 7.5A fuse (hot in ON or START) and the MEMORY 10A fuse (hot at all times), both in the I/P Junction Box (PHOTO 49).
Which ECM pins carry the CAN bus lines?
ECM pin 10 is CAN High and pin 35 is CAN Low, routed through joint connectors including JABAG, JM03, JM06, JE67, MF11, and EF11.
What indicator lamps in the instrument cluster are shown on this page?
CRUISE, CRUISE SET, CHECK ENGINE, and IMMO indicators, all controlled through the cluster's MICOM.
How does the immobilizer signal differ with and without button start?
With Button Start, the signal goes to the Smart Key Control Module (connector M14-A, pins 2 and 25); without Button Start, it goes to the Immobilizer Module (connector M36, pin 5). Both route to ECM pin 74 (ELG-A, IMMO Signal, Y wire).
Which ECM pin drives the Check Engine indicator?
ECM pin 25 (Engine Check IND.) on a Br/B wire, which connects through connector EM21 (pins 34/38) to the cluster.
