Troubleshooting ECM-P242000

Checking the status




- Ignition on
Check if the malfunction is permanent or intermittent by opening and closing the valve in the leakage diagnostics unit. Listen for a clicking sound when the valve opens/closes.
If the valve is not heard, this indicates a permanent malfunction. If the valve can be heard, this indicates that the malfunction is intermittent and not active right now.





Continue - Checking component and cables

-------------------------------------------------

Checking component and cables
Check the leakage diagnostics unit's connector for contact resistance and oxidation.
Check the valve's resistance between the leakage diagnostics unit's connector #3 and #4.
Check the cable between engine control module (ECM) #B48 (#C48) and the leakage diagnostics unit #2 for short-circuit to voltage.
Remedy as necessary.
