Relay Control Module Test
The relay control module is part of the under-hood fuse/relay box, and it contains these relays:
- PGM-FI main relay 1
- Ignition coil relay
- PGM-FI subrelay
- ETCS control relay
- Horn relay
If any of these relays fail the test, replace the under-hood fuse/relay box.
- Do the battery terminal disconnection procedure (see
USING THE GR8 BATTERY DIAGNOSTIC STATION
), then disconnect under-hood fuse/relay box connectors C (2P), E (14P), and H (9P).NOTE: All connector views are wire side of female terminals.

- Connect battery power to terminal C2.
PGM-FI main relay 1:
- Connect terminal E5 to body ground. There should be battery voltage between terminal H1 and body ground.
- Disconnect terminal E5 from the body ground. There should be no voltage between terminal H1 and the body ground.
Ignition coil relay:
- Connect terminal E5 to body ground. There should be battery voltage between terminal H6 and body ground.
- Disconnect terminal E5 from the body ground. There should be no voltage between terminal H6 and the body ground.
PGM-FI subrelay
- Connect terminals E5 and E13 to body ground. There should be battery voltage between terminal H9 and body ground.
- Disconnect terminal E5 from the body ground. There should be no voltage between terminal H9 and the body ground.
ETCS control relay:
- Connect terminals E5 and E14 to body ground. There should be battery voltage between terminal H7 and body ground.
- Disconnect terminal E5 from the body ground. There should be no voltage between terminal H7 and body ground.
- Connect battery power to terminal H3.
Horn relay:
- Connect terminal E4 to body ground. There should be battery voltage between terminal H4 and body ground, and between terminal H5 and body ground.
- Disconnect terminal E4 from the body ground. There should be no voltage between terminal H4 and body ground, and between terminal H5 and body ground.
