TROUBLE SHOOTING
PRELIMINARY INSPECTION
Verify customer complaint by operating system. Visually inspect for obvious signs of mechanical and electrical
damage. Check generator belt tension and condition. Ensure that battery voltage is within specifications. Inspect
for blown fuses and damaged relays.
Verify ground connection integrity between engine, body, battery and generator. Check for damaged wiring
harnesses and/or switches. Check for a broken or partially broken wire inside insulation, which could cause
system malfunction but prove good in a continuity/voltage check with system disconnected. Ensure any
aftermarket electronic equipment is properly installed. If fault is found, repair as necessary. If no fault is found,
check for conditions that might cause an intermittent situation.
SERVICE PRECAUTIONS
BATTERY DISCONNECT/CONNECT
Disconnect Procedures
1. On vehicles not equipped with TELE AID, go to step 5 . Vehicles equipped with TELE AID, switch
TELE AID into service mode by turning ignition ON.
2. Turn ON telephone and enter code "*#4610#" on handset.
3. Confirm that "No Telematics Service" appears on handset with okay.
4. Turn OFF handset.
5. Turn OFF ignition.
6. Open hood and open snap fasteners (1) on dust filter housing. See Fig. 2
.
7. Remove dust filter housing (2) exposing battery.
8. If not using quiescent current retention unit, go to step 14 . If using quiescent current retention unit, go to
next step.
9. Connect quiescent current retention unit by switching on quiescent current retention unit (7) and then first
connecting positive terminal (8) and negative terminal (9) of retention unit to positive cable and battery
ground (W10). See Fig. 3
.
10. On vehicles equipped with TELE AID, remove luggage compartment cargo anchoring lugs and remove
floor paneling.
11. Remove screws (1). See Fig. 4
.
12. Dismantle cover from TELE AID control module (A35/8).
13. Disconnect connection coupling for back up battery and remove back up battery.
14. Disconnect ne
gative battery cable (1) and insulate terminal. See Fig. 5. NOTE: Numbers and letters in text refer to numbers and letters in figures.

GF77.20-P-2002GH
Closing sliding /pop-up roof, function
19.2.97

MODEL
163 with CODE (414a) Electric glass sliding/pop-up roof

Function prerequisites

D
Voltage not too low or too high

D
Switch-on conditions for convenience control fulfilled

Function

The sliding roof and pop-up roof can be closed by pressing the

switch (SR, S13/2)
. The sliding/pop-up roof can only be closed by

continuously pressing the
switch (SR, S13/2)
.

The express close function is not available for safety reasons.


If the sliding/pop-up roof has not been synchronized, it opens only in

the pop-up roof direction each time the
switch (SR, S13/2) is

actuated. Upon reaching its end position, i.e. before the pop-up roof

is completely open,
synchronization
is accomplished.
After successful synchronization, the sliding/pop-up roof can then be

controlled without limitations.

Vehicles
up to 11.99:

The power for the
sliding/pop-up roof (M12)
is supplied via a

fuse directly to c. 30.

The power for the
switch (SR, S13/2)
is supplied via the

convenience relay (F1k14)
, which is actuated by the
all-activity

module (AAM, N10)
.

Vehicles
as of 12.99:

The power for the
sliding/pop-up roof (M12)
is supplied via a

fuse directly to c. 30. The power for the
switch (SHD, S13/2) is

supplied via a lead to the
extended-activity module (EAM,

N10/1) , this power is switched through only when the switch-on

conditions for the convenience control are fulfilled and the EAM is

coded accordingly.
