Consumer shutdown
To prevent the battery from being discharged due to continuous operation of consumers, the terminals to the consumers are shut down.
The CAN bus goes into standby a few minutes after terminal R is switched OFF. After 16 minutes, the power module transmits a signal for consumers to be shut down. When this happens, the CAN bus is briefly reactivated.
The following terminals are switched off:
- Terminal for "consumer shutdown, rear roof"
- Terminal for "consumer shutdown, front roof"
- Terminal for "consumer shutdown, interior lighting"
- Vehicles without telephone:
Terminal for "consumer shutdown, body"
- Vehicles with telephone:
After 60 minutes (can be encoded), the terminal for "consumer shutdown, body" is switched off. The output for the telephone drawer is connected to the terminal for "consumer shutdown, body".
The power module starts the monitoring off-load current.
If certain consumers are switched on, off-load current monitoring will not be active.
These consumers are needed for the following reasons:
- Legally stipulated consumers
(e.g. side lights, hazard warning lights)
- Occupant comfort
(radio, telephone)
