ON-VEHICLE TESTING
WIRING CONTINUITY
1. Connect voltmeter between generator B+ terminal and ground. Voltmeter should indicate battery voltage.
If battery voltage is not indicated, check battery and check wiring between generator and battery for
corrosion, loose terminals, etc.
2. Turn ignition on and ensure instrument cluster charge indicator light (battery symbol) comes on. If light
does not come on, check wiring between generator and warning light, including indicator bulb.
GENERATOR OUTPUT
1. Ensure connections at battery and generator are clean and tight. Ensure generator, engine and body are
properly grounded. Ensure generator drive belt is properly adjusted and in good condition.
2. Connect load tester/ammeter as per tester manufacturer's instructions. Connect voltmeter leads to battery
terminals. See Fig. 9
. Start engine and run at 2200 RPM for V6 or 2500 RPM for V8. Adjust load tester
to obtain maximum generator output. DO NOT allow voltage to drop to less than 12.7 volts.
3. Maximum generator output should be within a few amps of generator rated output stamped on generator.
If output is not within a few amps of generator rated output, check generator diodes. See DIODE TEST
.
Replace
generator as necessary.

Service Information: Compass in trip computer
22.10.00
MODELS
163.113 /154 /172 as of 1.9.00,
163.128 /157 /174 /175 with CODE (245) Trip computer
The compass is calibrated in the factory in order to compensate
for deviations caused by magnetic field intensity of the vehicle and
magnetic interference when operating the heated rear window.
Once the compass is calibrated, it never needs to be recalibrated
under normal operating conditions. If a strong deviation in magnetic
field intensity is detected, the compass automatically recalibrates
itself.
A calibration must be carried out if the compass is replaced.
Additionally, the user can fine tune the compass in order to adapt
it to the vehicle's surrounding area. By setting the respective
compass zone, the compass compensates for deviations in the
earth's magnetic field.
The calibration should take place at least 10 m from any source of
interference such as power lines, buildings and parked vehicles.
Zone setting
1
Press the MODE button on the trip computer
until the compass direction is displayed
2
Press the RESET button once
The current compass zone is displayed
3
Press the RESET button until the desired
compass zone is displayed
The maps for determining the correct
compass zone can be found in the owner's
manual. If the RESET button is not pressed
within 5 seconds, the point of the compass is
displayed again.
Compass calibration
4
Bring the compass to the compass zone
display mode
5
Press the MODE button once
Display shows
CAL-
on.
6
Press the RESET button for at least 2 seconds
The hyphen (
-
) in the display disappears.
The calibration mode is active and remains
active until the calibration process has
concluded. If the ignition is switched off and
on, calibration mode remains active, even if
CAL
no longer is displayed.
7
Drive two complete circles at a speed of
between 5 - 10 km/h
Heated rear window switched off.
8
Switch heated rear window on
9
Drive three full circles at a speed from 5 - 10
km/h.
Calibration process concluded.
Although the display can change from
CAL
to
the point of the compass before the
calibration drive has been concluded, the
calibration process is still active and must be
carried out exactly as described.

Convenience control, function
7.4.97
MODEL
163
The convenience control allows the driver to operate the electrical
seat adjustment, the power windows, the electric vent windows, the
electric outside rearview mirror as well as the electric sliding/pop-up
roof or the electric lamella sliding roof
when the ignition is switched
off.
To achieve this, the all-activity module (AAM) (N10) switches to the
corresponding loads via the convenience relay (F1k14)
circuit 30 .
As of 12.99 the vehicle is equipped with its own convenience relay for
seat adjustment (relay 1, F2k1). In addition the status of the
convenience control via CAN is transmitted to the extended activity
module (EAM, N10/1).
Conditions for control actuation
On all-activity module (AAM) (N10) configured for
I
up
to
11.99:
The convenience actuation becomes active as soon as
D
Circuit 15 ON is recognized
When circuit 15 is switched off, the convenience actuation is
deactivated after a door is opened
Otherwise
The convenience actuation is active in the following cases:
D
Circuit 15c ON
D
A front door is open
D
The remote control key is removed, however, the doors are not
yet opened
In both cases the convenience actuation remains active for 5 min.
Switch-on condition for circuit 15c
When the remote control key is inserted into the ignition lock, circuit
15c is switched on when the key is turned out of the zero position.
Circuit 15c switches off only after the remote control key is removed
from the ignition lock
