Final answer:
The Mode selector position to find malfunction codes when the MAL light reappears varies with different systems. It typically involves putting the device into a diagnostic or fault code retrieval mode as specified by the manufacturer's guidelines.
Step-by-step explanation:
The position of the Mode selector to find the malfunction codes when the MAL light reappears after turning the set off and back on will depend on the specific equipment or machinery you are dealing with. As there is a wide variety of systems that utilize such a light for malfunction indication, it’s important to refer to the manufacturer’s manual or diagnostic guide specific to that equipment. Commonly, there could be a diagnostic mode, service mode, or fault code retrieval mode that needs to be activated by positioning the Mode selector accordingly.
For example, in some automotive applications, you might need to turn the ignition switch to a particular position to access the fault codes after the MAL light has indicated an issue. In other electronic or computing equipment, there might be a sequence of buttons to press or hold to enter the diagnostic state where the system will display or flash the malfunction codes.
