SUBJECT

The Powertrain Control Module (PCM) on about 59,000 of the above vehicles may have been inadvertently programmed with software that may not run the Downstream Oxygen Sensor Slow Response Monitor as frequently as required by regulations.

This can allow an improperly operating Oxygen Sensor to go undetected and result in excessive exhaust emissions which may exceed EPA and California Emissions Standards.

REPAIR

The Powertrain Control Module (PCM) must be reprogrammed (flashed).

PARTS INFORMATION

Due to the likelihood that the required labels are already in your parts inventory, no labels will be distributed initially. The following label may be ordered as needed.

Each vehicle requires application of the following labels:

PARTS INFORMATION

Part Number	Description
04275086AD	Authorized Modifications Label

SPECIAL TOOLS

The following special tools are required to perform this repair:

NPN TechCONNECT PC
NPN wiTECH VCI Pod Kit
NPN Laptop Computer
NPN wiTECH Software

SERVICE PROCEDURE

NOTE: wiTECH must be used to perform this recall. This procedure must be performed with software release level 12.01 or higher. If the reprogramming flash for the PCM is aborted or interrupted, repeat the procedure.

A. Reprogram the PCM

Open the hood. Install a battery charger and verify that the charging rate provides 13.0 to 13.5 volts. Do not allow the charger to time out during the flash process. Set the battery charger timer (if so equipped) to continuous charge.
NOTE: Use an accurate stand alone voltmeter. The battery charger volt meter may not be sufficiently accurate. Voltages outside of the specified range will cause an unsuccessful flash. If voltage reading is too high, apply an electrical load by activating the park or headlamps and/or HVAC blower motor to lower the voltage.
Connect the wiTECH VCI pod to the vehicle data link connector located under the steering column.
Place the ignition in the "RUN" position.
Open the wiTECH Diagnostic application.
Starting at the "Select Tool" screen, select the row/tool for the wiPOD device you are using.
Enter your "User id" and "Password" , then select "OK".
Select the "Next" tab at the bottom of the screen.
From the "Vehicle View" screen, click on the PCM icon.
From the "PCM View" screen, compare the "Current ECU Flash Number" with the "New Part Number" listed on the "sort table". If the "Current ECU Flash Number" is the same as the "New Part Number" continue to Step 18 . If the part numbers are not the same, continue to Step 10 .
With the cursor over the desired flash file, click the small green arrow button on the right side of the screen.
From the "ECU Flash" screen follow the wiTECH screen instructions to complete the flash.
Once the flash is complete click the "OK" button on the "ECU Flash" screen.
Turn the ignition to the "OFF" position for 2 minutes.
Select "Vehicle View" from the "PCM View" screen.
From the "All DTC's" tab, select the "Clear Stored DTC's" button.
Select "OK" from the pop-up text box.
From the "PCM View" screen, compare the "Current ECU Flash Number" with the "New Part Number" listed on the "sort table". If the "Current ECU Flash Number" is the same as the "New Part Number" the flash is complete. If the part numbers are not the same, repeat Steps 8 through 17 .
Turn the ignition to the "OFF" position, remove the wiPOD and battery charger from the vehicle.
Continue with Section B. Install Authorized Modifications Label.

B. Install the Authorized Modifications Label

Type or print (with a ballpoint pen) the recall number, repair modification, dealer code and date on the Authorized Modifications Label (Figure 1 ).
Attach the label near the VECI label and then close the hood.
Complete Proof of Correction Form for California Residents.
NOTE: This recall is subject to the State of California Registration Renewal/Emissions Recall Enforcement Program. Complete a Vehicle Emission Recall Proof of Correction Form (Form No. 81-016-1053) and supply it to vehicle owners residing in the state of California for proof that this recall has been performed when they renew the vehicle registration.

EMISSIONS RECALL L34 - REPROGRAM PCM DOWNSTREAM OXYGEN SENSOR SLOW RESPONSE MONITOR

Dear: (Name)

Chrysler has determined that the 2010 and early 2011 model year Jeep _® Wrangler vehicles equipped with a 3.8L engine may require reprogramming of the Powertrain Control Module (PCM).

The problem is... The PCM on your Jeep (VIN: xxxxxxxxxxxxxxxxx) may have been inadvertently programmed with software that may not run the Downstream Oxygen Sensor Slow Response Monitor as frequently as required by regulations. This can allow an improperly operating Oxygen Sensor to go undetected and result in excessive exhaust emissions which may exceed EPA and California Emissions Standards.

What your dealer will do... Chrysler will repair your vehicle free of charge (parts and labor). To do this, your dealer will reprogram your vehicle's PCM. The work will take about 1/2 hour to complete. However, additional time may be necessary depending on service schedules.

What you must do... Simply contact your dealer right away to schedule a service appointment.

If you need help... If you have questions or concerns which your dealer is unable to resolve, please contact Chrysler at 1-800-853-1403.

California residents... The State of California requires the completion of emission recall repairs prior to vehicle registration renewal. Your dealer will provide you with a Vehicle Emission Recall Proof of Correction Form after the recall service is performed. Be sure to save this form since the California Department of Motor Vehicles may require that you supply it as proof that the recall has been performed.

Please help us update our records by filling out the attached prepaid postcard, if any of the conditions listed on the card apply to you or your vehicle. You may also update this information on the web at CCCCCCCCCCCCCCCCCCCCCCCCCC

If you have already experienced this condition and have paid to have it repaired, you may send your original receipts and/or other adequate proof of payment to the following address for reimbursement: Chrysler Recall Customer Assistance, P.O. Box 21-8007, Auburn Hills, MI 48321-8007, Attention: Reimbursement.

In order to ensure your full protection under the emission warranty provisions, it is recommended that you have your vehicle serviced as soon as possible. Failure to do so could legally be determined to be a lack of proper maintenance of your vehicle. Further, without this repair, your vehicle may fail a state or local emission inspection test.

We are sorry for any inconvenience but trust that you understand our interest in clean air. Thank you for your attention to this important matter.
