Signal Missing. Permanent Fault

Signal missing. Permanent fault

Checking the connector








- Ignition off
- Check the injector connector. Check for contact resistance and oxidation
- Reinstall the components, reconnect the connectors etc.
- Ignition on
- Activate the injector.
A "click" should be heard when the injector is activated.
If the injector is now OK, the fault was caused by poor contact in the connector.

Is the injector working?

Yes - FAULT FOUND

No - Checking components and wiring

-------------------------------------------------

Checking components and wiring
Check the resistance of the injector between terminals 1 and 2.
Check the cable between injector terminal 2 and control module:
- terminal #A16 (#A16) (ECM 2310)
- terminal #A15 (#A15) (ECM 2320)
- terminal #A33(#A33) (ECM 2330)
- terminal #A32 (#A32) (ECM 2340)
- terminal #A34 (#A34) (ECM 2350)
- terminal #A14 (#A14) (ECM 2360).
Check the power supply between system relay terminal 3 and injector terminal 1. Check for an open-circuit.
Remedy as necessary.

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off
- Reconnect connectors, reinstall components etc.
- Ignition on
- Activate the relevant injector.
A "click" should be heard when the injector is activated.





Is the injector working?

Yes - Verification completed

No - Fault-tracing information

Information

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?

Yes - Exit Fault-Tracing

No - Attempt New Test
