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 RELEASE 14.01 OR HIGHER TO
PERFORM THIS PROCEDURE.
SUBJECT:
Flash: MIL Illumination P2073 or P2074 MAP/TPS, or P0400 EGR System, or P2279 Intake Air System
OVERVIEW:
This bulletin involves replacing the air filter with a MOPAR filter and selectively erasing and
reprogramming the Powertrain Control Module (PCM) with new software.
NOTE: The codes can be found in any combination or individually.
MODELS:
(MK)
2011-2014
Compass/Patriot
(International Only)
NOTE: This bulletin applies to vehicles with 2.2L 14 Single TD OM651 Engine (sales
code ENE) built on or before September 19, 2013 (MOH 0919.XX).
SYMPTOM/CONDITION:
Customers may complain that they have experienced a MIL light and the vehicle is in LIMP
IN mode. Upon further investigation the Technician may find P2073 or P2074 MAP/TPS or
P2279 - Intake Air System alone or along with P0400 EGR System code:
•
•
•
•
P2073
P2074
P0400
P2279
-
Manifold Pressure/Throttle Position Correlation
MAP/TPS Correlation - High Air Flow I Vacuum Leak Detected
EGR System Flow Malfunction
Intake Air System Leak
The PCM requires to be Flashed if the vehicle comes in with the symptom where fault
code P2279, P2074, P2073, and/or P0400 is present. The new software update removes
fault codes P2074/P2073 which were tied to reaching a maximum correction factor on the
MAF Sensor. Codes P2074/P2073 were not considered needed as they are duplicated by
P2279 and P0400 functions . The new software also updates the threshold for P2279 to
-2-

-30% deviation from -15% to provide for further insurance that there will not be a false fault
code creation.
DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all engine systems are functioning as designed. If DTC's other than
the one 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 or if the technician finds the OTC,
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.
1.
Replace the Air Filter with the latest MOPAR Certified Filter which has two certification
dots as shown below ().
Air Filter
I1- Two Certification Dots
2.
Reinitialize MAF Sensor using wiTECH .
NOTE: Reinitialized MAF Sensor using wiTECH each time an Air Filter is replaced is
required for the 2.2L OM651 Turbo Diesel Engine.
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.

4.
Reprogram the PCM with the latest software. Follow the detailed service procedures
available in DealerCONNECT/TechCONNECT, Refer To Group 8 - Electrical >
Electronic Control Modules - Service Information > Module - Powertrain Control >
Standard Procedures > PCM/ECM Programming.
After PCM reprogramming, the following must be performed:clear any DTC's that
may have been set in other 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.
