Hallo an Euch!
Nach langer Zeit bin ich mal wieder hier.
Natürlich ein Problem.
Tempomat von meinem Disco 1 V8i 3,9er von 1997.
Keine Funktion.
Unterdruck Schläuche sind neu!
Die Pumpe ist natürlich "wartungsfreundlic" versteckt. Kaum erreichbar
Gibt sicher auch ein Relais. Kann auch defekt sein.
Ich hoffe sehr einen "alten Hase" hierzu finden.
Danke im Voraus.
Viele Grüße
Wilfried

Hallo Wilfried,

das kann kann an xx Sachen liegen, liegt da überhaupt Unterdruck an, d.h. die Anlage ist dicht und die UPumpe läuft ?


zur Funkton:
CRUISE CONTROL SYSTEM - V8i/Tdi AUTO EDC
Description
The cruise control system consists of
electro-mechanical devices, and comprises of the
following components.

ELECTRONIC CONTROL UNIT (ECU)
The microprocessor based ECU evaluates the signals
provided by the driver controls, brake pedal switch,
clutch pedal switch on manual models, and the
vehicle speed sensor. The ECU activates the vacuum
pump as required. The ECU also has a memory
function for set speed storage.
Driver operated switches
The main cruise control switch is located in the
auxiliary switch panel and activates the cruise control
system. The steering wheel switches provide
’set/accelerate’ and ’resume/decelerate’ features.
These switches provide the interface between driver
and cruise control system.

Brake pedal switch
The brake pedal switch is located under the lower
dash attached to the brake pedal mounting bracket.
The switch provides for fast disengagement of the
cruise control system and rapid return of the throttle
levers to the idle position when the brake pedal is
applied.

Clutch pedal switch
The clutch pedal switch is located under the lower
dash attached to the clutch pedal mounting bracket.
The switch provides for fast disengagement of the
cruise control system and rapid return of the throttle
levers to the idle position when the clutch pedal is
applied.

Vehicle speed sensor
The vehicle speed sensor is located on the side of the
transfer box adjacent to park brake. The sensor
provides road speed data to the ECU. The cruise
control system cannot be engaged until the road
speed exceeds 45 km/h, (28 mph) the system will
automatically disengage at a road speed of 42 km/h
(26 mph).

Vacuum pump
The vacuum pump is energised when the main cruise
control switch is operated, and is actuated by the
steering wheel and brake pedal switches. The pump
provides a vacuum source to the cruise control
actuator. A control valve in the pump provides for
steady increase of road speed or purge of the system
when the brake pedal is applied.

Actuator
The actuator provides the servo mechanism link
between the cruise control system and throttle linkage
and is operated by vacuum from the vacuum pump.

Neutral lockout relay - automatic vehicles
The relay module is located in the right hand side
footwell, accessible by removing the trim casing.
The function of the relay module is to disengage the
cruise control system if neutral, or park, is selected in
the main gearbox, when the system is engaged.

Engine speed trip ECU - Manual vehicles
This unit is located in the right hand side footwell,
accessible by removing the trim casing.
The function of the unit is to disengage cruise control
if engine speed exceeds 5000 rev/min.

Hallo juergenr.
Danke
Der Unterdruck.
Habe mit meiner Messvorrichtung (Lt. Citroën Werkstatthandbuch hergestellt).
Geht nur bei laufendem Motor im Stand.
Hauptschalter vom Tempomat gedrückt.
Kein Unterdruck vorhanden.
Schläuche Neuwertig und absolut dicht.
Ich denke, dass der Tempomat nur im Fahrbetrieb durch betätigen des Schalters am Lenkrad aktiviert wird.
Viele Grüße
Wilfried
