EFI Main Relay DOHC (Swift)
- Remove relay from main fuse box in engine compartment, located between battery and left fenderwell. See Fig 1 . Turn ignition on. Check for battery voltage on White/Red wire terminal and Black/White wire terminal of relay connector. Battery voltage should be present.
- Check continuity between White/Red wire terminal and White/Blue wire terminal of relay. If there is continuity, replace relay. Check resistance between Black/White and White/Black wire terminals of relay. Resistance should be 56-84 ohms. If resistance is not as specified, replace relay.
- Apply battery voltage to Black/White wire terminal and ground to White/Black wire terminal. Check continuity between White/Blue and White/Red wire terminals. If continuity does not exist, replace relay.
