SYMPTOM/CONDITION:
A small number of customers may experience the following symptom or conditions or a
Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the technician
may find the following (DTCs):
JC Vehicles equipped with a 2.4L engine (Sales Code ED3 or ED7):
•
•
•
•
•
•
•
•
•
•
**P0335 - Crankshaft Position Sensor Circuit.
P050B - Cold Start Ignition Timing Performance.
P2299 - Brake Pedal Position / Accelerator Pedal Position Incompatible.**
U0140 - Lost Communication With Body Control Module. Attempting to clear the
DTC may be unsuccessful.
P0456 - Evap purge system small leak.
2-1 downshift improvement.
Charging system duty cycle enhancement to improve starting performance in low
ambient temperatures.
P219A - Bank 1 Air-Fuel Ratio Imbalance.
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.

Mode 6 data accuracy enhancement for generic scan tools.
Garage shift engagements into D may be harsh at times after shutdowns of 10-30
minute duration.
Harsh upshifts generated by backing out of the accelerator pedal.
Harsh shifts can be felt after acceleration/deceleration driving maneuvers from a
stop.

DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all related 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, 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 software. Detailed instructions for flashing control
modules using the wiTECH Diagnostic Application are available by selecting the
application’s “HELP” tab.
2. Clear any DTCs that may have been set in any module due to reprogramming. The
wiTECH application will automatically present all DTCs after the flash and allow them
to be cleared.
POLICY:
Reimbursable within the provisions of the warranty.

FAILURE CODE:
The dealer must choose which failure code to use. If the customer came in with an
issue and if the dealer finds a software update 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, 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.
