STAR ONLINE PUBLICATION
Case Number: S2018000011
Release Date:
10/27/2020
Symptom/Vehicle Issue: Issue includes a fault code(s) set in the Powertrain Control
Module (PCM) for P0299, P0300, P0301, P0302, P0303, and/or P0304 after
performing the PCM software update process for Customer Satisfaction Notification
(CSN) W05.
Discussion: If, after performing the PCM software update process on the PCM for
CSN W05 and any of the fault codes for P0299, P0300, P0301, P0302, P0303 and/or
P0304 are active, stored, or pending, please perform the PCM software update
process again and re-evaluate the symptoms. Engineering has advised the concern is
not an issue with the flash, but potentially a poor internet connection or a low vehicle
system voltage condition during the update that may cause the fault codes to set after
the update. If any of the noted fault codes return after re-performing the PCM software
update process, please proceed with published diagnostics for any fault codes that
return.
NOTE: Vehicles that have a perceived idle quality issue during cold start that is not
accompanied by any fault code(s) should be considered characteristic and no repairs
are necessary.
