14. Remove the PGM-FI main relay.
15. Connect battery power to the PGM-FI main relay 7P connector terminal No.2 and connect ground to the PGM-FI main relay 7P connector
terminal No.1. Then check for continuity between the PGM-FI main relay 7P connector terminals No.5 and No.4.
NOTE: Use the terminal numbers shown. Ignore the terminal numbers molded into the relay.
Is there continuity?
YES - Go to step 16.
NO - Replace the PGM-FI main relay and reset.
16. Connect battery power to the PGM-FI main relay 7P connector terminal No.5, and connect ground to the PGM-FI main relay 7P connector
terminal No.3. Then check for continuity between the PGM-FI main relay 7P connector terminals No.7 and No.6.
Is there continuity?
YES - Go to step 17.
NO - Replace the PGM-FI main relay and reset.
17. Connect battery power to the PGM-FI main relay 7P connector terminal No.6, and connect ground to the PGM-FI main relay 7P connector
terminal No.1. Then check for continuity between the PGM-FI main relay 7P connector terminals No.5 and No.4.
Is there continuity?
YES - The PGM-FI main relay is OK.
NO - Replace the PGM-FI main relay and retest.
