RODEO Y22SE 2.2L ENGINE DRIVEABILITY AND EMISSION

DIAGNOSTIC TROUBLE CODE (DTC) P0563 SYSTEM VOLTAGE HIGH

060R100045

Circuit Description

The powertrain control module (PCM) monitors the
system voltage on the ignition feed terminals to the PCM.
A system voltage Diagnostic Trouble Code will set
whenever the voltage is above a calibrated value.  DTC
P0563 is a type A code.

Conditions for Setting the DTC

D

Ignition ON.

D

System voltage is above 16V.

The above conditions are met for 900 test failures at 15
min.

Action Taken When the DTC Sets

D

The PCM will not illuminate the malfunction indicator
lamp (MIL) for the first time the malfunction is detected.

D

The PCM will store as Failure Records conditions
which were present when the Diagnostic Trouble Code
was set. This information will not be stored as Freeze
Frame data.

Conditions for Clearing the MIL/DTC

D

A history Diagnostic Trouble Code P0563 will clear
after 40 consecutive warm–up cycles have occurred
without a fault.

D

Diagnostic Trouble Code P0563 can be cleared by
using the Scan Tool’s ”Clear Info” function.

Diagnostic Aids

Check for a faulty charging system components.

RODEO Y22SE 2.2L ENGINE DRIVEABILITY AND EMISSION

DIAGNOSTIC TROUBLE CODE (DTC) 

P0601 INTERNAL CONTROL MODULE MEMORY CHECK SUM ERROR

014RX002

Circuit Description

The powertrain control module (PCM) used in this vehicle
utilizes an electrically erasable programmable read–only
memory (EEPROM). The EEPROM contains program
information and the calibrations required for engine,
transmission, and powertrain diagnostics operation.
Unlike the PROM used in past applications, the EEPROM
is not replaceable. When the PCM is replaced or a
calibration update is required, the PCM must be
programmed using a Tech 2. For the EEPROM
programming procedure, Refer to On–Vehicle Service in
Powertrain Control Module and Sensors for procedures.
If the PCM detects a check sum error then DTC P0601 will
set.  DTC P0601 is a type A code.

Conditions for Setting the DTC

D

Ignition on.

D

Check sum of soft ware and calibration not equal
expected check sum.

Action Taken When the DTC Sets

D

The PCM will illuminate the malfunction indicator lamp
(MIL) the first time the malfunction is detected.

D

The PCM will store conditions which were present
when the Diagnostic Trouble Code 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 Diagnostic Trouble Code P0601 will clear
after 40 consecutive warm–up cycles have occurred
without a fault.

D

Diagnostic Trouble Code P0601 can be cleared by
using the Scan Tool’s ”Clear Info” function.

Diagnostic Aids

D

Diagnostic Trouble Code P0601 indicates that the
contents of the EEPROM have changed since the
PCM was programmed. The only possible repair is
PCM reprogramming or replacement. Check service
bulletins to program the replacement PCM with the
correct software and calibration for the vehicle.
