What fuse powers the instrument cluster circuit in this MFI diagram?

The CLUSTER 10A fuse, which is hot in ON or START and fed via the I/P junction box (see Power Distribution SD110-3 and fuse details SD120-1).

Which ECM pins carry the CAN bus signals?

ECM connector C01 pin 62 is CAN-Hi and pin 64 is CAN-Lo.

Which ECM pin drives the malfunction indicator (check engine) lamp?

Pin 70 of connector C01, labeled 'Output MAL Function Indication Lamp'; pin 94 drives the Fuel Cap Open lamp.

What connectors are used for the throttle position and crankshaft position sensors?

The throttle position sensor uses connector C23 (pins 2, 1, 3) and the crankshaft position sensor uses connector C06 (pins 2, 1).

Which ECM pins control the cooling fan relays?

Fan relay control uses ECM pins 28 (Low) and 23 (High), with reference to the cooling system diagram SD253-1.

This document is page 4 of the Multiport Fuel Injection (MFI) control system wiring diagram for a Hyundai Accent with the G4ED engine and manual transmission (diagram SD313-4). It shows the circuit from the CLUSTER 10A fuse (hot in ON or START, fed from the I/P junction box) to the instrument cluster warning lamps (Engine Check / MIL, Fuel Cap Open), tachometer signal, and CAN-Hi/CAN-Lo lines. The diagram details ECM connector C01 pin assignments, including pin 70 (MIL output), 94 (fuel cap open lamp), 67 (engine speed signal to tachometer), 62/64 (CAN-Hi/CAN-Lo), 8 (A/C pressure switch input), 30 (A/C ON signal), 45 (A/C relay control), plus sensor power/signal/ground pins for the throttle position sensor (C23), crankshaft position sensor (C06), A/C pressure transducer (E08), fuel tank pressure sensor (F19), front wheel speed sensor RH (E50, w/o ABS), ABS control module (E31), power steering switch (E53), and fan relay control (low/high). Wire colors and gauges (e.g., 0.5G/B, 0.3Gr, 0.5Br/O, 2.5B) and intermediate connectors (M09, EM01/EM02, EC01/EC02/EC03, EF01) are labeled, along with cross-references to other diagrams (SD110-3, SD120-1, SD200-1, SD253-1, SD921-1, SD940-3, SD971-3/8).
