Steering Pad Switch Circuit: Description

This circuit sends an operation signal from the steering pad switch assembly to the navigation receiver assembly.

If there is an open in the circuit, the navigation system cannot be operated using the steering pad switch assembly.

If there is a short in the circuit, the resulting condition is the same as if a switch were continuously pressed. Therefore, the navigation receiver assembly cannot be operated using the steering pad switch assembly, and the navigation receiver assembly itself cannot function.
