Main Relay (Computer/Fuel System): Testing and Inspection
INSPECTIONContinuity Inspection
1. Using an ohmmeter, check that there is continuity between terminals 1 and 3.
2. Check that there is no continuity between terminals 2 and 4.
3. Check that there is no continuity between terminals 3 and 4.
If continuity is not as specified, replace the relay.
Operation Inspection
1. Apply battery voltage across terminals 1 and 3.
2. Using an ohmmeter, check that there is continuity between terminals 2 and 4.
