Checking the Control
The diagnostic trouble code (DTC) is stored when a button or switch has been depressed for a long time.
If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults can be caused by interference at start up or can be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs.
Check that the button or switch does not stick in the activated position.
Remedy as necessary.
