6VD1 3.2L ENGINE DRIVEABILITY AND EMISSIONS

Diagnostic Trouble Code (DTC) P0604 PCM RAM Error

060RY014

Circuit Description

The powertrain control module (PCM) uses Main CPU
RAM and Watchdog CPU RAM.

Conditions for Setting the DTC

D

This code detects inconsistencies between Main CPU
RAM and Watchdog CPU RAM.

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 P0604 will clear after 40 consecutive
warm-up cycles have occurred without a fault.

D

DTC P0604 can be cleared by using the Tech 2 “Clear
Info” function or by disconnecting the PCM battery
feed.

Diagnostic Trouble Code (DTC) P0606 PCM Internal Performance

060RY014

Circuit Description

The input/output devices in the PCM include
analog-to-digital converters, signal buffers, counters, and
special drivers. The PCM controls most components with
electronic switches which complete a ground circuit when
turned “ON”. These switches are arranged in groups of 4
and 7, called either a surface-mounted quad driver
module (QDM), which can independently control up to 4
output terminals, or QDMs which can independently
control up to 7 outputs.

Conditions for Setting the DTC

D

This code detects inconsistencies between Main CPU
A/D converters and Watchdog CPU A/D converters.

Action Taken When the DTC Sets
