What fuses power the cooling fans on this diagram?

The RAD 30A fuse feeds the radiator fan circuit, the COND 30A fuse feeds the condenser fan circuit, and a SNSR 10A fuse (hot with main relay on) feeds relay control power. All are in the E/R Fuse & Relay Box.

How many cooling fan relays are there and what are their connectors?

Three relays: the Radiator Fan Relay (connector E68), Condenser Fan Relay #1 (connector E65), and Condenser Fan Relay #2 (connector E69), all located in the E/R Fuse & Relay Box.

Which PCM/ECM pins control the fan relays?

Fan Relay Control (Low) is pin 21 (A/T) / 28 (M/T), and Fan Relay Control (High) is pin 23 (A/T) / 23 (M/T).

Where do the fan motors ground?

The condenser fan motor grounds at G16 (via a 2.0B wire from E13 pin 2); ground point G14 is also shown. The radiator fan motor output (2.0G from E37 pin 2) routes to Condenser Fan Relay #2 (SD253-1).

How is the engine coolant temperature sensor wired?

The Engine Coolant Temperature Sensor & Sender uses connector C27: the sender feeds the instrument cluster via C27 pin 2 (through CC02, EC03, EM02, M09-3), while the sensor uses a 0.5P Sensor Signal wire to PCM/ECM pin 77 and a 0.5G Sensor Ground wire to pin 73 C01-1 (A/T) / 35 C01 (M/T).

This document is a cooling fan wiring diagram uploaded for a 2008 Hyundai Accent. It shows the engine compartment (E/R) fuse and relay box containing the SNSR 10A, RAD 30A, and COND 30A fuses, plus three relays: the Radiator Fan Relay (connector E68), Condenser Fan Relay #1 (E65), and Condenser Fan Relay #2 (E69). Power flows from a 'hot with main relay on' feed and 'hot at all times' feeds through these fuses and relays to the Radiator Fan Motor (connector E37) and Condenser Fan Motor (connector E13). The diagram includes wire gauge and color codes (e.g., 2.0R, 2.0G, 2.0B, 0.3Gr, 0.5Y/B), ground points G14 and G16, and cross-references to other diagram sections (SD110-2 power distribution, SD253-1, SD971-3/SD971-8 blower & A/C controls). The right side shows the Engine Coolant Temperature Sensor & Sender (connector C27) feeding both the Instrument Cluster (via M09-3, EM02, EC03, CC02) and the PCM/ECM. PCM/ECM pin assignments are given for both A/T and M/T versions, including Fan Relay Control (Low/High), A/C Relay Control, Input A/C Pressure Switch, A/C 'ON' Signal, Sensor Signal, and Sensor Ground. Photo references (e.g., PHOTO 9, 10, 12, 14, 23) point to component location images.
