6E–279

6VD1 3.2L ENGINE DRIVEABILITY AND EMISSIONS

Diagnostic Trouble Code (DTC) P0601 PCM Memory

060RY014

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. Refer to 

On-Vehicle Service

in 

Powertrain Control Module and Sensors for the

EEPROM programming procedure.

Conditions for Setting the DTC

D

The PCM detects an internal program fault (check sum
error).

Action Taken When the DTC Sets

D

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

D

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

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 P0601 will clear after 40 consecutive
warm-up cycles have occurred without a fault.

D

DTC P0601 can be cleared by using the Tech 2 “Clear
Info” function.

Diagnostic Aids

D

DTC P0601 indicates that the contents of the
EEPROM have changed since the PCM was
programmed.  The only possible repair is PCM
replacement.  Remember to program the replacement
PCM with the correct software and calibration for the
vehicle.

Diagnostic Trouble Code (DTC) P0602 PCM Programming Error

060RY014

Circuit Description

The powertrain control module (PCM) uses Main CPU
and Watchdog CPU software/calibration.

Conditions for Setting the DTC

D

This code detects inconsistencies between Main CPU
and Watchdog CPU software/calibration.

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 P0602 will clear after 40 consecutive
warm-up cycles have occurred without a fault.

D

DTC P0602 can be cleared by using the Tech 2 “Clear
Info” function or by disconnecting the PCM battery
feed.
