1997 MERCEDES-BENZ ML430 ABS

SAFETY SHUTOFF (WSA) - FUNCTION - GF82.30-P-3005GH
MODEL 163 Applicable as of 1.9.00
Safety shutoff
The intermittent wipe function is interrupted when the vehicle comes to a complete stop and at least one of
the front doors is open. Any wipe cycle in progress is completed before wipers come to a halt.
Wiping resumes when both front doors are closed and/or the vehicle is put into motion.
The safety shutoff therefore only operates when the vehicle is at a complete stop. This ensures that the
intermittent wiping feature remains available during driving even if a door jamb switch is defective.
ANTI-LOCK PROTECTION FOR WIPER MOTOR, FUNCTION - GF82.30-P-4008GH
MODEL 163
The all-activity module(AAM) (N10) recognizes that the wiper motor (M6/1) is locked up because of the
absence of signals from the cam switch.
If signals are not recognized for longer than 1 s the front wiper motor relay (F1k17) is no longer actuated.

The anti-lock protection is only effective in the function interval wiping . In other wiper stages the AAM does
not have influence on the wiper motor.

automatically, after voltage to the radio (A2) was interrupted
manually, by activating the "SPRA" menu in the navigation mode
Loading the language requires approx. 20 s.
If the system is switched off while loading the language, the language data is lost and must be reloaded again.
Avoid strong vibrations to the vehicle (e.g. extremely bumpy roads) while the language is being loaded.
The navigation processor is integrated in the radio (A2).
BASIC LOCATION FINDING, FUNCTION - GF82.61-P-3006D

Basic representation of the basic location finding shown on model 210
Basic location finding (dead reckoning) is the basic function of continuous location finding. It is permanently
carried out by the navigation processor that is integrated in the radio (A2) when the ignition is switched on
(approx. once per second) and is irrespective of the data of the DVD map. After switching off the ignition, the
current position is stored for the duration of the system shut-off delay time.
Fig. 46: Identifying Basic Location Finding Function

The following information is calculated with the aid of basic location finding:
Distance traveled
Absolute vehicle direction (compass direction)
Direction of travel (forward or reverse)
Calculation of distance traveled
The navi
gation processor receives the wheel speed signal of the following components:

Risk of explosion/risk of fire
Highly flammable materials in the vicinity of damaged, energized xenon bulbs may result in explosion or cause
fires.
Risk of injury
UV light may escape when operating xenon bulbs not properly installed in the xenon headlamps. This UV light
may cause damage to the eyes (conjunctival infection) and to skin burns (sunburns) if skin is unprotected.
In both intact or faulty xenon headlamps, hot or glowing components may cause serious burn injuries if they
come into contact with unprotected skin or eyes.
Glass splinters produced by the destruction of xenon bulbs may cause cut injuries in unprotected skin and
unprotected eyes.
Risk of poisoning
When xenon bulbs are destroyed, serious health problems may be caused if the mercury vapors produced are
inhaled or if mercury compounds or toxic salts are ingested or absorbed through the skin. Possible
consequences include nausea, vomiting and gastrointestinal disruptions as well as degradation of the kidneys
and the central nervous system. Skin and eye damage may also result.
Safety precautions/instructions
Persons with electronic implants (e.g. pacemakers) must never work on xenon headlamps.
Wear safety shoes (with rubber soles).
Prior to working on xenon headlamps (e.g. replacing parts, hooking up test equipment, etc.), the complete
lighting system must be switched off and the xenon headlamps must be disconnected from the on-board
electrical system.
If the xenon headlamps are switched on, never touch components under high voltage.
If the xenon headlamps are switched on, maintain a clearance of at least 30 mm to components under high
voltage.
Avoid all contact with hot components.
Wait at least 3 min after switching off xenon bulbs before touching them.
Do not damage or destroy xenon bulbs.
Safety precautions/instructions
Never operate xenon bulbs unless they are properly installed in xenon headlamps with UV-absorbing
headlamp lenses.
Keep all highly flammable materials away from working area.
Wear suitable protective gloves and safety glasses.
Ensure that the workplace is sufficiently ventilated.

Set radio as follows: Set station with poor reception (music) and fader, bass, treble and balance in
position 0 (shown in display).
Check AM and FM wave bands by driving in a circle in a yard (open-air grounds) to establish the
reception quality.
Possibly repeat the test with an identical vehicle for comparison.
It is absolutely essential to perform the comparison measurement at the same location and with the same
station setting .

COVER FIBER OPTIC CABLE - AR82.95-P-0005-01A
Do not remove protective covers too early from the fiber optic cable coupling (3) or the device connection
(4) because contaminated or scratched surfaces may absorb the light. Fiber optic cables must not be kinked,
routed over sharp edges or bent in radii of less than 25 mm, otherwise the fiber optic cable core will be
yellowed and broken. Yellowed or broken fiber optic cables weaken the light.
The work procedure is shown on components of the digital data bus (D2B).
1. Carefully detach the fiber optic cable coupling (3) from the device connection (4) and cover it with a
protective cap (1), stop plug (2) or a clean rag.
