Checking the status of the diagnostic trouble code (DTC)
- Ignition off.
- Start and stop the engine a few times.
- Let the engine idle.
Read off diagnostic trouble codes (DTCs).
Is diagnostic trouble code (DTC) DSA-223 still stored?
Yes - Checking the DSA control module
No - Faulty signal. Intermittent fault
-------------------------------------------------
Checking the DSA control module
- Ignition off.
- Expose the DSA control module.
- Disconnect the DSA control module.
- Connect a new DSA control module alongside.
- Start and stop the engine a few times.
- Let the engine idle.

Is diagnostic trouble code (DTC) DSA-223 still stored?
Yes - Replacing the component
No - Replacing the component
-------------------------------------------------
Replacing the component
The old DSA control module is OK: Reinstall it.
Note! It is vital that any diagnostic trouble codes (DTCs) in the engine control module (ECM) and the DSA control module are remedied before the engine control module (ECM) is replaced.
FENIX 5.1
- Try a new engine control module (ECM)
EMS 2000
- Try a new engine control module (ECM) according to Replacing the engine control module (ECM) Replacing the Engine Control Module (ECM).
Select Continue when the fault has been remedied.
Continue - Verification
