2. Measure the voltage between the terminal "2" electromagnetic clutch relay connector and ground. If the voltage matches the voltage of the battery, proceed to step number 3, if it does not match, replace the relay box.
3. Jumper the leads "1" And "2" electromagnetic clutch relay connector.
If the electromagnetic clutch worked, proceed to point #7, if it did not work, proceed to point #4.
4. Remove the jumper from the terminals "1" And "2" electromagnetic clutch relay connector.
5. Disconnect the electromagnetic clutch connector.
6. Check the continuity between the output "1" electromagnetic clutch relay connector and output "1" electromagnetic clutch connector.
If continuity is present, remove and check the electromagnetic clutch, if not, repair an open in the wire circuit between the electromagnetic clutch and the relay box.
7. Remove the jumper from the terminals "1" And "2" electromagnetic clutch relay connector.
8. Turn the ignition key to position "ON".
9. Measure voltage between terminal #5 of the solenoid clutch connector and ground. If the voltage matches the battery voltage, then proceed to step No. 10, if it does not match, replace the relay unit.
10. Turn the ignition key to position "OFF".
11. Install the magnetic clutch relay into the relay box.
12. Set the air conditioner switch to position "OFF" and turn the ignition key to position "ON".
13. Measure the voltage between the terminal "18" connector of the electronic control unit for the injection system and mass.
If the voltage matches the battery voltage; install a working electronic control unit for the injection system and diagnose again, if it does not match, repair an open in the wire circuit between the electronic control unit for the injection system and the electromagnetic clutch relay.
