Battery -A-, DISCONNECTING AND CONNECTING, 0K4 AND VH2: Notes
- The 12 V system is supported by the 48 V system via the Voltage Converter, 48 V/12 V -A7-. So the only way for the 12V vehicle electrical system to be de-energized is to de-energize the 48V system beforehand.
- For subsequent work on the SCR system, wait until all of the reducing agent has returned after switching off the ignition.
