Closed-circuit current measurement
If the vehicle battery is discharged for an unknown reason,
perform a closed-circuit current measurement as the first test.
For diagnostic purposes, it is important to not disconnect the
battery. Disconnecting the battery may reset a faulty control
unit, preventing proper diagnosis.
The following test is generally completed overnight using a
multimeterwith a closed circuitcurrent measurement adaptor
with a recording function
- Check that battery voltage is 12 volts or higher. If lower,
recharge battery.
- Switch off electrical consumers (interior lights, telephone,
aftermarket equipment, or others).
- Open luggage compartment and remove battery trim panel.
Use screwdriver to lock latch on trunk lid or hatch, simulating
closed luggage compartment. Close other doors.
- Open driver's door, then close it, simulating driver entering
vehicle.
- Switch ignition to RUN position for at least five seconds, then
turn ignition to OFF position. This simulates driving vehicle.
- Open and close driver's door, simulating driver leaving
vehicle.
- Lock car and arm alarm.
- Wait at least 16 minutes for consumer cut-off.

Body-General
Tailgate
The E39 Sporl Wagon tailgate is large with a low sill for easy
cargo loading. The tailgate opens to an angle of
88" mea-
sured from the rear roof pillar (D-pillar) and to a height of
2029
mm (79.8 in) measured from the ground to the upper edge of
the raised tailgate.
The rear window is bonded to a load bearing frame and can
be opened separately from the main tailgate. Tailgatesupport
gas springs are recessed into cavities in the roof.
Tailgate lock system
A mechanical tailgate lock cylinder is not used; the tailgate is
opened by the unlock pad above the license plate, the remote
tailgate switch located in the drivers kick panel, or via
FZV
(Iteyless entry) control.
4 An emergency release mechanism is incorporated into the
latch assembly to open the hatch from the vehicle interior if a
malfunction occurs.
The tailgate lock assembly includes an automatic soft close
(SCA) feature. The electrical operation of SCA is a function of
central body electronics
(ZKE Ill). The SCA actuator is locat-
ed in the rear cowl panel below the tailgate. The actuator is
controlled by a load relay in the General Module. A locking
cam is mounted on an eccentric that is driven by the actuator.
4 The SCA cam always turns in the same direction to open or
close the tailgate. The cam turns
180" to open or to close.
When the cam turns in the up direction the notch in the cam
SCA actuator pushes on a lever on the back of the latch in the tailgate. This
mechanically unlocks the latch. The tailgate is raised up and
can be opened.
