THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 18-023-14, DATED
APRIL 1, 2014, WHICH SHOULD BE REMOVED FROM YOUR FILES. ALL REVISIONS
ARE HIGHLIGHTED WITH **ASTERISKS.** REVISIONS INCLUDE ADDITIONAL
SYMPTOMS FOR THE 2.4L ENGINE (SALES CODES ED3 OR ED7) AND A NEW
LABOR OP.
HELP USING THE wiTECH DIAGNOSTIC APPLICATION FOR FLASHING AN ECU IS
AVAILABLE BY SELECTING “HELP” THEN “HELP CONTENTS” AT THE TOP OF
THE wiTECH DIAGNOSTIC APPLICATION WINDOW.
THE wiTECH SOFTWARE LEVEL MUST BE AT **15.02** OR HIGHER TO PERFORM
THIS PROCEDURE.
SUBJECT:
Flash: 2.4L, 3.6L Powertrain System Improvements/Enhancements
OVERVIEW:
This bulletin involves reprogramming the Powertrain Control Module (PCM) with the latest
available software.
MODELS:
2014
(JC)
Journey
NOTE: This bulletin applies to vehicles equipped with the following:
• 2.4L engine (sales code ED3 or ED7) equipped with either a 4 speed
automatic transmission (sales code DFF) or 6 speed automatic
transmission (sales code DG2).
• 3.6L engine (sales code ERB) equipped with a 6 speed automatic
transmission (sales code DG2).

SYMPTOM/CONDITION:
The following powertrain system improvements/enhancements are included in this
software release:
Vehicles equipped with a 2.4L engine (sales code ED3 or ED7).
•
•
•
•
**Charging system duty cycle enhancement to improve starting performance in low
ambient temperatures.**
**P219A - Bank 1 Air-Fuel Ratio Imbalance. (applies to vehicles equipped with the 4
speed transmission (sales code DFF) only.**
Enhanced Automatic Oil Change Indicator(EAOCI) system enhancements that force
the use of the severe duty cycle algorithm anytime the PCM is replaced. The vehicle
duty cycle information used in the EAOCI calculation is stored in the PCM and
cannot be recovered/transferred when the controller is replaced. As a result, the
severe duty cycle is used in these scenarios to ensure the customer receives a
timely oil change required message.
Mode 6 data accuracy enhancement for generic scan tools.
Vehicles equipped with a 3.6L engine (sales code ERB).

DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all vehicle systems are functioning as designed. If DTCs other than
the ones listed above are present record them on the repair order and repair as necessary
before proceeding further with this bulletin.
If the customer describes the symptom condition above or the tech finds any of the DTCs
set, perform the Repair Procedure.
REPAIR PROCEDURE:
NOTE: Install a battery charger to ensure battery voltage does not drop below 13.2
volts. Do not allow the charging voltage to climb above 13.5 volts during the
flash process.
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
1. Reprogram the PCM with the latest available software. Detailed instructions for
flashing modules using the wiTECH Diagnostic Application are available by selecting
the “HELP” tab on the upper portion of the wiTECH window, then “HELP CONTENTS.”
This will open the Welcome to wiTECH Help screen where help topics can be
selected.

NOTE: After PCM reprogramming, the following must be performed:
2. Clear any DTCs that may have been set in any modules due to reprogramming. The
wiTECH application will automatically present all DTCs after the flash and allow the
tech to clear them.
POLICY:
Reimbursable within the provisions of the warranty.
