Checking Other Diagnostic Trouble Codes (DTCs), Engine Control Module (ECM)







NOTE: The quick test of the fuel tank system must be activated when running this fault-tracing. Check so that none of diagnostic trouble codes (DTCs) ECM-4000, ECM-400A, ECM-4310, or ECM-4320 are stored in the engine control module (ECM), which interrupts the leakage diagnostic.

- Ignition on.
- Activate reading off diagnostic trouble codes (DTCs).

If any of these diagnostic trouble codes (DTCs) are stored they must be remedied and erased first.

Is diagnostic trouble code (DTC) ECM-4000, ECM-400A, ECM-4310 or ECM-4320 stored?
