Volvo EC360B Instrument Panel Operation

Instrument panel operation
1. Lamp and buzzer check procedure

2022 Volvo PTT Tech Tool PTT 2.8.130
Before starting the engine, if you turn the start switch to the ON position all lamps are turned ON for 3 seconds. At the same time the buzzer is operated 2 times with the cycle of 1.0 second ON and 1.0 second OFF.
Check if all indicator lights come on, and if not, check for burnt-out light bulbs, and the plugin connectors (connector A, B) of the printed circuit board.
2. Central warning and buzzer soundW signal indicates engine status whether engine is running or not.IC in the instrument panel receives warning signal and this W signal and then decides that this situation is warning case or not.
For example, when we turn the key switch from OFF to ON, we can see only charge warning lamp and engine oil low pressure without central warning and buzzer sound because there is no signal from alternator W terminal.
3. Quick fit release operation
4. Quick fit re-engage operation
