Signal Too Low

Signal too low

Checking components and wiring
Check the cable that relates to the diagnostic trouble code (DTC). Check for a short-circuit to ground.
Check between:
- Engine control module (ECM) terminal #A16 (#A16) and injector terminal #2 (ECM-200D, injector 1)
- Engine control module (ECM) terminal #A34 (#A34) and injector terminal #2 (ECM-201D, injector 2)
- Engine control module (ECM) terminal #A15 (#A15) and injector terminal #2 (ECM-202D, injector 3)
- Engine control module (ECM) terminal #A33 (#A33) and injector terminal #2 (ECM-203D, injector 4)
- Engine control module (ECM) terminal #A14 (#A14) and injector terminal #2 (ECM-204D, injector 5).
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.

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
