Signal Too Low - Permanent Fault

Signal too low. Permanent fault

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 #A34 (#A34) (ECM 2320)
- terminal #A15 (#A15) (ECM 2330)
- terminal #A33(#A33) (ECM 2340)
- terminal #A14 (#A14) (ECM 2350).
Check for a short-circuit to ground.
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.
