SYMPTOM/CONDITION:
**A small number of customers may experience a Malfunction Indicator Lamp (MIL)
illumination. Upon further investigation a technician may find one of more of the following
Diagnostic Trouble Codes (DTCs) set in the PCM memory.
•
•
•
•

P20C2 - Reductant Heater 3 Control Circuit Performance.
P204F - Reductant System Performance.
P20E9 - Reductant Pressure Too High.**
P016A-00 - Excessive Time To Enter Closed Loop Air/Fuel Ratio Control.

In addition to addressing the above DTCs, the following powertrain system
improvements/enhancements are also included in this software release.
•
•

Enhancements to improve A/C compressor relay duty cycle operation to prevent
ignition off battery draw.
Powertrain system improvements to enable EGR cleaning routine.

DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all vehicle systems are functioning as designed. If DTCs are
present, record them on the repair order and repair as necessary before proceeding further
with this bulletin.
REPAIR PROCEDURE:
NOTE: The Transmission Control Module (TCM) software must also be at the latest
available software level upon completion of this repair. Refer to all applicable
published service bulletins regarding Transmission Shift Enhancements for
detailed repair procedures and labor times.
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. Using wiTECH, verify if the PCM is at the latest available software. Does the PCM
software need to be updated?
a. Yes>>> Proceed to Step #2.
b. No>>> Proceed to Step #6.
2. Reprogram the PCM with the latest 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.
3. Clear any DTCs 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.
4. Under the PCM “System Tests” perform the “SCR DEF Tank Fluid Level Reset”
procedure.
5. Turn the ignition off for 35 seconds to complete the flash. Proceed to Step #6.

6. Verify the TCM software is programmed with the latest available software level. Refer
to all applicable published service bulletins regarding Transmission Shift
Enhancements for detailed repair procedures and labor times. Proceed to Step #7.
7. With the ignition key off, test for voltage on fuse F62 (10 amp red) located in the under
hood Power Distribution Center (PDC) using a volt meter connected to ground. Was
12 volts measured at the fuse with the ignition off?
a. Yes>>>Further diagnosis and repair is required. Refer to all applicable published
TSBs or service information in DealerCONNECT/TechCONNECT regarding ignition
off battery draw.
b. No>>> The bulletin is now complete. If no software update was needed, use Labor
Op 18-19-04-BS to close out the RRT portion of this service action.
