GROUP:    Vehicle Performance
DATE:     August 12, 2011

 

SUBJECT:

Flash: MIL Illumination And/Or Bump Jerk Feeling

 

OVERVIEW:

This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software.

 

MODELS:

2008 – 2010 (MK) Compass/Patriot (Mexico Markets Only)
2008 – 2010 (PM) Caliber (Mexico Markets Only)

 

NOTE: This bulletin applies to vehicles equipped with a 1.8L, 2.0L or 2.4L engine (sales code EBA or ECN or ED3) with export emissions (sales code NA1).

 

SYMPTOM/CONDITION:

The customer may experience a MIL illumination. Upon further investigation the

Technician may find Diagnostic Trouble Code (DTC) P0129 – Barometric Pressure Out Of Range Low active or stored. 1.8L, 2.0L or 2.4L engines

The customer could also report a firm brake pedal feel. This condition could happen if the vehicle is started at altitudes of 3000 meters (9000 feet) or higher. The software was changed to equalize manifold pressure while cranking the engine during these conditions. 1.8L, 2.0L or 2.4L engines

The customer could also report a bump or jerking feeling under the following conditions for 2.0L or 2.4L engines with an automatic transmission:

  1. Vehicle is traveling between 25 MPH (40 KPH) to 30 MPH (48 KPH) and the driver lifts their foot of the accelerator pedal. The condition could happen again as the vehicle slows down to 15 MPH (24 KPH) with the no accelerator input a second bump may be felt.
  2. Vehicle coasting between 3 MPH (4 KPH) and 15 MPH (24 KPH) with no accelerator pedal input and the driver steps on the accelerator pedal a bump or jerking feeling may be felt.

Updating the software will correct the conditions listed above.

 

DIAGNOSIS:

Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in

TechCONNECT, verify all engine and transmission systems are functioning as designed. If DTC’s are present other then the one listed above record them on the repair order and repair as necessary before proceeding further with this bulletin.

If the above condition is present, perform the Repair Procedure.

 

PARTS REQUIRED:

Qty. Part No. Description
1 04275086AB Label, Authorized Modification

 

REPAIR PROCEDURE:

NOTE: Install a battery charger MIL Illumination And/Or Bump Jerk Feeling - 2008-2010 Jeep Compass/Patriot & Dodge Caliber » small light 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 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 Programming. After reprogramming, the following must be performed:
  2. 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.
  3. Type the necessary information on the “Authorized Modification Label” and attach it near the VECI label.

 

POLICY:

Reimbursable within the provisions of the warranty.

 

TIME ALLOWANCE:

Chrysler J2534 Application Overview

The Chrysler J2534 System is a combination of the J2534 Application (2010 and newer Model Year Support) and the Chrysler J2534 Flash Application (2009-1996 Model Year Support). J2534 aftermarket users are required and responsible for installing the J2534 device driver provided by the device manufacturer. If you need support installing the device driver software contact the device manufacturer. See the related article “Chrysler J2534 Manual” for additional information. Chrysler J2534 application provides below capabilities:

 

New J2534 Application:
New J2534 Application Application Usage and Support
  • Provides support for 2010 and newer model years.
  • New J2534 Application requires users to work online. An active internet connection and bandwidth (1.5 Mbps) is required to use J2534 application.
  • ECU reprogramming files are automatically downloaded via the application.
  • J2534 Applicable ECUs can be reprogrammed, if a flash is available.

 

The Chrysler J2534 Flash Application:
The Chrysler J2534 Flash Application Application Usage and Support
  • Provides support for 2009 – 1996 model years.
  • ECU reprogramming support for emission control modules only (ECM, PCM, TCM and CTV).

 

Chrysler Recommended J2534 Devices

For Chrysler recommended J2534 device, see below table.

Additional Information and Known Issues / Concerns:

If you are reprogramming the 5.9L diesel engine controller on the 1996-2008 Dodge RAM vehicle, it is necessary to also reprogram the VIN after the ECU has been flashed.  To write the VIN to the ECU, you may use aftermarket software support, or use an OEM FCA US LLC scan tool (DRBIII or StarSCAN). For more information, see the FCA US LLC Scan Tool Lease Options section.

  • 1996-2009 ALL PCMs

If you are REPLACING a PCM or ECM and the vehicle is equipped with a theft deterrent system (Sentry Key), it must be initialized to properly function with the Anti Theft module. You also need to reprogram the VIN when replacing a PCM or ECM.  To write the VIN to the ECU and initialize the PCM to work with the theft deterrent system, you may use aftermarket software support, or use an OEM FCA US LLC scan tool (DRBIII or StarSCAN). For more information, see the FCA US LLC Scan Tool Lease Options section.


FCA US LLC Scan Tool Lease Options:

  • For 2009 model year vehicles and prior, it may be necessary to use either a DRBIII or a StarSCAN to perform function required after ECU replacement.  To lease the DRBIII call 1-586-532-8400 or click here.
  • Beginning with 2010 MY, function required to replace an ECU will be supported via the J2534 application.
