Note: This TSB is written by me, not Ford. I've seen this issue in a dozen vehicles now.
Issue: The user may experience a "Charge station fault" error and a flashing red ring indicator on the charge port 30 seconds after plugging in a Level 1 or Level 2 charger (J1772 plug). A P0D56:24 code will be set in the SOBDM. On some vehicles, a 12V drain may also occur after this fault is set until the plug is removed. If the user does not address the charge station fault and leaves the plug in, the 12V battery may drain in the next several hours, generating additional errors and/or starting issues. This issue is caused by operator error or a dimensionally incorrect J1772 that does not fully insert and latch into the charging port. NOTE: This is issue often associated with Grizzl-E brand chargers.
Resolution: Advise the user to always ensure the the J1772 plug is fully inserted until the latch clicks, and verify a blue indicator is shown on the charge port before walking away. If the J1772 plug is not easily to push in and latch, it may be dimensionally incorrect and defective. Advise the user to replace the EVSE cord. The charge port locking pin should also be inspected for damage per TSB 22-2345.
Tip: If this issue occurs, you must fully unplug and replug to clear the fault and resume charging!
Explanation: The J1772 handle contains an internal switch (S3) that is opened when the release button is pressed. If the plug is not fully inserted into the charge port, the latch will be lifted up on the ramp which prevents the S3 switch from closing (the release button won't come up fully). The car reads the status of this switch through the plug and sets a P0D56:24 code after 30 seconds if the S3 switch still hasn't closed (no charging will occur). On some vehicles (due to bad software?) the setting of this charge fault will cause the vehicle to stay awake and drain the 12V battery until the plug is removed. Many people will plug in and walk away without verifying the status lights, and will miss the error message that comes 30 seconds after plugging in. As mentioned above I've seen this issue happen primarily with Grizzl-E chargers, it seems they may have a dimension tolerance issue with their J1772 plugs that makes them a very tight fit, so this issue is much more likely to occur.
Suggestion: Ford, change the timing on this error from 30 seconds to 3 seconds so the user sees it before they walk away. Maybe add a honk in case they are walking away and there is a problem with the J1772 connection. Also change your fault handling (if you haven't yet) so the car goes to sleep while the charge error is active.
