RODEO 6VD1 3.2L ENGINE DRIVEABILITY AND EMISSIONS

Diagnostic Trouble Code (DTC) P0563 System Voltage High

060R200058

Circuit Description

The powertrain control module (PCM) monitors the
system voltage on the ignition feed terminals to the PCM.
A system voltage DTC will set whenever the voltage is
above a calibrated value.

Conditions for Setting the DTC

D

Ignition “ON”.

D

System voltage is above 16 volts for 40 seconds.

Action Taken When the DTC Sets

D

The PCM will ON the MIL after second trip with
detected the fault.

D

The PCM will store conditions which were present
when the DTC was set as Freeze Frame and in the
Failure Records data.

Conditions for Clearing the MIL/DTC

D

A history DTC P0563 will clear after 40 consecutive
warm-up cycles have occurred without a fault.

D

DTC P0563 can be cleared by using the Tech 2 “Clear
Info” function or by disconnecting the PCM battery
feed.

Diagnostic Aids

If the DTC sets when an accessory is operated, check for
a poor connection or excessive current draw.

RODEO 6VD1 3.2L ENGINE DRIVEABILITY AND EMISSIONS

Diagnostic Trouble Code (DTC) 

P0565 Cruise Main Switch Circuit Error

060R100094

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:
