5 Series E60 M5 (S85) SAL
The Check Control message appears in the instrument cluster.
The separate loudspeaker is discontinued.
Modifications from 03/2007:
To coincide with the new model appearing in 03/2007, the E60, E61 is equipped with option 3AC "trailer coupling with
electrically pivoted ball head"). Since this time, a separate Check Control symbol has been provided for the system.
In the event of a system error, the trailer module will generate a Check Control message. The instrument cluster
displays the Check Control message.
Brief description of components
The following components supply signals for the electric trailer coupling release or fully automatic trailer coupling:
-
Button for the trailer coupling release
> E90, E91, E92, E93
Pressing the button operates the trailer coupling release.
The ball head moves from the locked position to an intermediate position.
Two coloured LEDs are integrated into the button (green and red). The indicator lamp shows the system status.
While the ball head is not locked, the indicator lamp in the button will light up red.

-
Button for the electrically pivoted trailer coupling
> E60, E61
Pressing the button prompts the ball head to pivot out or in as far as each limit position.
Two coloured LEDs are integrated into the button (green and red). The indicator lamp shows the system status.
While the ball head is not locked, the indicator lamp in the button will flash red.

-
Rear-lid contact switch
The rear lid must be open when the trailer coupling is operated. The rear lid contact switch in the rear lid lock
transmits the signal to the control unit for the trailer coupling release (E90, E91, E92) or for the electrically
pivoted trailer coupling (E60, E61).
At the same time, the luggage compartment lights are switched on by this contact.
-
Microswitch in drive for trailer coupling release
> E90, E91, E92, E93
The microswitch is a switch with 3 connections. The microswitch recognises whether the ball head is locked in
one of its two end positions (folded out or folded in). The microswitch transmits the signal to the trailer coupling
release control unit.

Microswitch for trailer detection
E60, E61
The microswitch for trailer detection is built into the trailer socket. If the trailer connector is inserted in the trailer
socket, the ball head cannot be pivoted in.

Hall-effect sensor in drive system for the electrically pivoted trailer coupling
E60, E61
The Hall-effect sensor is integrated into the drive system. The entire pivoting travel of the ball head is monitored
with the aid of the Hall-effect sensor.
The drive system's rotary movement is transmitted by the Hall-effect sensor to the control unit for the electrically
pivoted trailer coupling in the form of a Hall-effect sensor signal.
