SYMPTOM/CONDITION:
A small number of customers may experience one or more of the following symptoms or a
Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the technician
may find one or more of the following Diagnostic Trouble Codes (DTCs) set in the
Powertrain Control Module (PCM):
•
•
•
•
•
•
•
•
•
**U0140 - Lost Communication With Body Control Module (LD and LX).**
U0140 - Lost Communication With Body Control Module (TIPM) stored in the Engine
Control Module (ECM) memory (LC vehicles).
P1621 - O2 Sensor Reference Voltage Circuit Low.
P1622 - O2 Sensor Reference Voltage Circuit High.
P0606 - Internal Control Processor.
P219A - Air-Fuel Ratio Cylinder Imbalance Bank 1.
P0300 - Multiple Cylinder Misfire (applies only to vehicles using a block heater in
ambient temperatures greater than -20°F (-29°C).
Technicians may find that the original vehicle Frequency Operated Button Integrated
Key (FOBIK) does not function properly following replacement of the Wireless
Ignition Node (WIN/WCM). The Secret Key information stored in the PCM may be
corrupt. This update will restore the PCM’s ability to store/transfer valid Secret Key
information (LC vehicles).
Accuracy improvements for the Automatic Oil Change Indicator (AOCI) system.
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 any
of 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. Perform the “PCM Replaced” function located in wiTECH under the WCM/WIN module
view under the Miscellaneous Functions tab. This will transfer the current/valid Secret
Key information from the WIN/WCM to the PCM. (applies only to LC vehicles).
3. 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 allow them
to be cleared.
