Component Test

1. Unplug the connector from the EFI Main Relay, (located on the RH side of the engine compartment).
2. Using an Ohmmeter, check for continuity between terminals 1 and 3.

Testing EFI Relay:

3. Check that there is NO continuity between terminals 2 and 4.
4. If not as specified, replace the EFI Main Relay.
5. Apply battery current across terminals 1 and 3.

Testing EFI Relay Operation - Current Applied:

6. Using an Ohmmeter, check for continuity between terminals 2 and 4.
7. If operation is not as specified, replace the EFI Main Relay.
8. Remove the battery leads and reconnect the relay.

NOTE: Refer to ECU POWER SUPPLY for circuit test of the EFI Main Relay.
