6VE1 3.5L ENGINE DRIVEABILITY AND EMISSIONS

Diagnostic Trouble Code (DTC)

P0565 Cruise Main Switch Circuit Error

D06R200090

Circuit Description

The cruise control keeps the vehicle running at a fixed
speed until a signal canceling this fixed speed is received.
When the main switch is turned on with the vehicle in the
running mode, the battery voltage is applied to power train
control module(PCM). When a signal from the control
switch is input to PCM while the vehicle is in this state, the
cruise control system is activated. Also, while the PCM is
operating, the “CRUISE MAIN” indicator light in the meter
assembly lights up.

Conditions for setting the DTC

D

The Ignition is “ON’’.

D

Engine is running.

D

System voltage is between 11.5 volts and 16 volts.

D

The switch contact remains on for 15 seconds or more.

D

Noises are generated by poor switch contact 60 times
within 1 second.

Action Taken When the DTC Sets

D

The PCM will not illuminate the malfunction indicator
lamp (MIL).

D

The PCM will store conditions which were present
when the DTC was set in the Failure Records data only.

Conditions for Clearing the MIL/DTC

D

The PCM will turn the MIL “OFF” on the third
consecutive trip cycle during which the diagnostic has
been run and the fault condition is no longer present.

D

A history DTC P0565 will clear after 40 consecutive trip
cycle during which the warm up cycles have occurred
without a fault.

D

DTC P0565 can be cleared using the Tech 2 “Clear
Info” function or by disconnecting the PCM battery
feed.

Diagnostic Aids

An intermittent may be caused by the following:

D

Poor connections.

D

Mis routed harness.

D

Rubbed through wire insulation.

D

Broken wire inside the insulation.

Check for the following conditions:

D

Poor connection at PCM-Inspect harness connectors
for backed out terminals, improper mating, broken
locks, improperly formed or damaged terminals, and
poor terminal to wire connection.

D

Damaged harness-Inspect the wiring harness for
damage. If the harness appears to be OK, observe the

cruise main switch display on the Tech 2 while moving
connectors and wiring harnesses related to the sensor.
A change in the display will indicate the location of
the fault.

If DTC P0565 cannot be duplicated, the information
included n the Failure Records data can be useful in
determined vehicle mileage since the DTC was last
set.

If it is determined that the DTC occurs intermittently,
performing the DTC P0565 Diagnostic Chart may
isolate the cause of the fault.
