Monitor System Performance:

• After addressing the issue, monitor the seat switch functionality to ensure normal operation and that the fault does not reappear.

Note:

Regular inspection and maintenance of the seat switch and associated wiring can prevent this fault. Ensuring that the seat switch is correctly positioned and functioning properly during routine checks is crucial for reliable operation.
