Capacity of the emergency battery (Volvo On Call/Volvo On Call Plus)
This parameter indicates the remaining capacity of the internal emergency battery. The emergency battery is only available for phone modules (PHM) with Volvo On Call/Volvo On Call Plus functionality.
The emergency battery is only used when activating the Volvo On Call/Volvo On Call Plus service and if there is no power supply.
The remaining capacity is calculated by the phone module (PHM).
Measurement range 0-100%.
100% is full capacity.
The diagnostic trouble code (DTC) stores a diagnostic trouble code (DTC) when the capacity drops to 30%.
- 0% corresponds to 0 minutes call time
- 10% corresponds to approximately 5 minutes call time
- 20% corresponds to approximately 10 minutes call time
- 30% corresponds to approximately 15 minutes call time
- 40-50% corresponds to approximately 20 minutes call time
- 60% corresponds to approximately 30 minutes call time
- 70-100% corresponds to more than 30 minutes call time.

General
All the values given below are between the terminals stated in column 1 and terminal #1 in column 2 (signal ground). This applies unless otherwise indicated in brackets.
Note. It is important to connect the breakout box and check the ground terminals before taking readings.
