HARNESS INSPECTION PROCEDURE

COMPONENT TEST PROCEDURE
1. Remove the multiport fuel injection relay.





2. Check the continuity between the multiport fuel injection relay terminals.

Terminals 3 - 5 Connected (approximately 95 Ohms)
Terminals 2 - 5 Connected (approximately 95 Ohms)
Terminals 6 - 7 Connected (approximately 35 Ohms)
Terminals 6 - 8 Connected only one way





3. By using the jumper wire, connect the terminal 7 of the multiport fuel injection relay to (+) terminal of the battery and the terminal 6 to (-) terminal of the battery.

CAUTION: If jumper leads are not connected properly the relay will be damaged.

4. While connecting the jumper wire on the side of (-) terminal of the battery, check continuity between the terminals 1 and 4 of the multiport fuel injection relay.

Jumper wire connected: 0.0 Ohms
Jumper wire disconnected: Infinite Ohms (open circuit)





5. By using the jumper wire, connect the terminal 2 of the multiport fuel injection relay to (+) terminal of the battery and the terminal 6 to (-) terminal of the battery.
6. While connecting and disconnecting the jumper wire on the side of (-) terminal of the battery, check continuity between the terminals 1 and 4 of the multiport fuel injection relay.

Jumper wire connected: 0.0 Ohms
Jumper wire disconnected: Infinite Ohms (open circuit)





7. By using the jumper wire, connect the terminal 5 of the multiport fuel injection relay to (+) terminal of the battery and the terminal 6 to (-) terminal of the battery.

8. While connecting and disconnecting the jumper wire on the side of (-) terminal of the battery, check continuity between the terminals 2 and 4 of the multiport fuel injection relay.

Jumper wire connected: 0.0 Ohms
Jumper wire disconnected: Infinite Ohms (open circuit)

9. Replace the multiport fuel injection relay, if malfunction exists.
