Operation CHARM: Car repair manuals for everyone.

Load Deactivation

If the vehicle is locked up, some loads are disconnected from the supply voltage in order to conserve the battery. The load disconnection output is switched off after approx. 10 minutes for this purpose.

The loads are switched on by switching on terminal 86 S (buzzer contact), terminal 15 or by recognition of a valid transponder key.

Power-on behavior
The function depends on programmed national variant.

Variant 1
The output is controlled when terminal 15 is switched on or if a door is open.

Variant 2
The output is controlled if terminal 15 is switched on and also remains switched on after terminal 15 is switched off, until a door is opened. The output is switched off no later than when the vehicle is locked.
