5 Series E60 525d (M57TU) SAL
System functions
Depending on the equipment configuration, the body-gateway module can control the following functions or register
signals (in alphabetical order):
-
Door mirrors
The body-gateway module (KGM) controls the functions of the outside mirrors in the basic version and with
optional additions.
•
Basic version of outside mirror
(only mirror heating and mirror adjustment)
The body-gateway module directly activates the motors for horizontal and vertical mirror adjustment.
The body-gateway module directly actuates the mirror heating.
•
Outside mirror with optional equipment
(mirror memory, automatic kerb viewer, electrochromic outside mirror, mirror folding function, courtesy
lighting)
The body-gateway module controls the control electronics in the outside mirror via the LIN-bus if the outside
mirror is equipped with one of these items.

Bistable relay
The bistable relay and micro-power module have been integrated in the body-gateway module. In the event of
closed-circuit current transgressions, the body-gateway module disconnects the electric loads from terminal 30g-
f via the bistable relay (closed-circuit current transgression: when the vehicle does not assume the rest status).
The following electric loads are connected to terminal 30g-f (power supply, front, fuses F34 to F41):
•
CA: Comfort Access
•
CDC: CD changer
•
JNAV or KNAV: Navigation system Japan or navigation system Korea
•
COMBI: Instrument cluster
•
M-ASK / CCC: Multi-audio system controller / Car Communication Computer
•
SZL: Steering column switch cluster
•
TCU or ULF: Telematics Control Unit or universal charging and hands-free device
Switch-on conditions:
The bistable relay is activated (contact closed) under one of the following conditions:
•
Connecting the battery
•
Unlocking the vehicle
•
Change in status of door contacts or boot lid
•
Terminal R ON
Conditions required for switch-off:
A CAN message requests the loads to switch off if the closed-circuit current is too high and the starting
capability limit of the battery is reached (afterrunning time approx. 2 minutes).
If the closed-circuit current is still too high after the afterrunning time has elapsed, a reset is performed for
approx. 10 seconds prior to final shut-down. This reset is performed to eliminate any malfunctions in the control
units connected to the bistable relay.
The closed-circuit current is monitored again after the reset. The bistable relay is no longer activated (contact
