Main Relay

WARNING: This page is about a different car, the 1990 Daihatsu Rocky and 1990 Daihatsu Charade. However, it is still accessible from the selected car via links, so may be relevant.

The main relay provides battery voltage to terminals +B1 and +B2 of ECU when ignition is turned on and engine rotation is detected. The EFI fuse No. 1 supplies battery voltage to main relay.
