Construction
• The fuel pump relay is located on the relay and fuse block.
• A normally open relay has been adopted for the fuel pump relay. When electric current flows to the coil, the contact point is drawn by the generated electromagnetic power and switches on.
Operation
1. The contact point is on (1) when the fuel pump relay coil is energized by the battery power from the main relay.
2. Power is supplied (2) to the PCM for the fuel pump control module operation.
