Signal Too High - Permanent Fault
Signal too high. 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 supply voltage.
Hint: Use a test lamp with at least a 3 W bulb to determine whether the cable is short-circuited to supply voltage.
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 - VERIFIED
No - VERIFICATION FAILED

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.
