Control unit cutoff in case of fault
Cutoff in case of fault is only available on vehicles with High equipment level (e.g. on vehicles with CCC or
M-ASK).
Cutoff in case of fault helps to maintain the vehicle's ability to start.
All control units and components on terminal 30g-f are cut off if any of the following faults develop:
1.
Control units frequently woken up after terminal R is switched OFF: Some control units do not "go to
sleep", but rather remain active.
2.
Prolonged undervoltage on bus systems
3.
Data buses do not "go to sleep" after terminal R is switched OFF.

Data transfer for power supply
The CAS (Car Access System) forwards the data for the terminal control as follows:
•
Terminal R ON or OFF
•
Terminal 15 ON or OFF
•
etc.
The CAS switches the corresponding relays for the following terminals:
•
Terminal 15
•
Terminal 30g
The junction box electronics switch the corresponding relay for the following terminal:
•
Terminal 30 g-f
The control units on these terminals are supplied with power and "woken up".
The corresponding vehicle systems are activated.
The consumers are primarily supplied via terminal 30g and terminal 30g-f (only on vehicles with High equipment
level). However, certain consumers are also supplied directly from terminal 30.
For example, the anti-theft alarm must also be active when the ignition is switched off.
