...vor 2 Wochen das letzte Mal gefahren - ohne Probleme.
Gestern wieder mal auf die Autobahn...Tempomat und Overdrive gehen nicht.
In Ami-Foren gesucht, Ursachen gibt es zahlreiche, aber es gibt eine Verbindung zwischen diesen beiden Sachen.
Hab mich mal drunter gelegt, alle Stecker scheinen zu sitzen und die Kabel intakt zu sein, abgezogen habe ich sie noch nicht (waren ja vor paar Monaten noch runter wegen der Getrieberevision). Batterie habe ich auch für ne Stunde abgeklemmt, ändert sich aber nix. Sicherungen sind auch alle ok.
Irgendwelche Tips ?? Danke !
In einem US-Forum steht folgendes:
5.9L Diesel Engines With Automatic Trans.
If equipped with a diesel powered engine and an
automatic transmission, an electric vacuum pump
and vacuum lines are used to supply vacuum to the
speed control servo. A vacuum reservoir is not used.
DIAGNOSIS AND TESTING - ROAD TEST
Perform a vehicle road test to verify reports of
speed control system malfunction. The road test
should include attention to the speedometer. Speedometer
operation should be smooth and without flutter
at all speeds.
Flutter in the speedometer indicates a problem
which might cause surging in the speed control system.
The cause of any speedometer problems should
be corrected before proceeding. Refer to Instrument
Cluster for speedometer diagnosis.
If a road test verifies a system problem and the
speedometer operates properly, check for:
² A Diagnostic Trouble Code (DTC). If a DTC
exists, conduct tests per the Powertrain Diagnostic
Procedures service manual.
² A misadjusted brake (stop) lamp switch. This
could also cause an intermittent problem.
² Loose, damaged or corroded electrical connections
at the servo (if used). Corrosion should be
removed from electrical terminals and a light coating
of Mopar MultiPurpose Grease, or equivalent,
applied.
² Leaking vacuum reservoir (if used).
² Loose or leaking vacuum hoses or connections (if
used).
² Defective one-way vacuum check valve (if used).
² Secure attachment of both ends of the speed control
servo cable (if used).
² Smooth operation of throttle linkage (if used)
and throttle body air valve.
² Failed speed control servo (if used). Do the servo
vacuum test.
CAUTION: When test probing for voltage or continuity
at electrical connectors, care must be taken
not to damage connector, terminals or seals. If
these components are damaged, intermittent or
complete system failure may occur.
