DESCRIPTION
- *1: w/ Accessory Meter
- *2: w/o Accessory Meter
If there is an open in the circuit, the audio system cannot be operated using the steering pad switch assembly*1 or steering pad switch LH*2.
If there is a short in the circuit, the same condition as when the switch is continuously depressed occurs.
Therefore, the radio and display receiver assembly cannot be operated using the steering pad switch assembly*1 or steering pad switch LH*2, and the radio and display receiver assembly itself cannot function.
