Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P240700

The engine control module (ECM) checks the function of the leakage diagnosis unit by measuring the current through the leakage diagnosis pump.
If the Engine control module (ECM) registers that the current curve is unreasonably noisy, the control module interprets that the reference measurement has produced a faulty result and the diagnostic trouble code is generated.
The diagnostic trouble code can be diagnosed when leakage diagnosis is running.
