NOTE: This bulletin applies to vehicles built on or before August 20, 2015 (MDH 0820XX) equipped with a 3.6L engine (Sales code ERB).

 

SYMPTOM/CONDITION:

A small number of customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation a technician may find the following Diagnostic Trouble Codes (DTCs) set in the PCM memory.

  • P0301- Cylinder 1 Misfire
  • P0302- Cylinder 2 Misfire
  • P0303- Cylinder 3 Misfire
  • P0304- Cylinder 4 Misfire
  • P0305- Cylinder 5 Misfire

DIAGNOSIS:

Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all engine systems are functioning as designed. If DTCs or symptom conditions, other than the ones listed above are present, record the issues on the repair order and repair as necessary before proceeding further with this bulletin.

If the customer describes the symptom/condition listed above or if the technician finds the DTCs, 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 control 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.
  2. Clear all DTCs that may have been set in any module due to reprogramming. The wiTECH application will automatically present all DTCs after the flash and allows them to be cleared.

 

POLICY:

Reimbursable within the provisions of the warranty.

 

TIME ALLOWANCE:

Labor Operation No: Description Skill Category Amount
18-19-06-ET Module, Powertrain Control (PCM) - Reprogram Module, Powertrain Control (PCM) Reprogram (0 - Introduction) 8 - Engine Performance 0.2 Hrs.

NOTE: The expected completion time for the flash download portion of this procedure is approximately 4minutes. Actual flash download times may be effected by vehicle connection and network capabilities.

 

FAILURE CODE:

The dealer must choose which failure code to use. If the customer came in with an issue and the dealer found updated software to correct that issue, use failure code CC, for all other use failure code RF.

  • If the customer’s concern matches the SYMPTOM/CONDITION identified in the Service Bulletin, than failure code CC is to be used.
  • If an available flash is completed while addressing a different customer concern, failure code RF is to be used.

RF Routine Flash
