SYMPTOM/CONDITION:
A small number of customers may experience a Malfunction Indicator Lamp (MIL)
illumination or a less than desired powertrain response when operating their vehicles in
high ambient temperatures. Upon further investigation the technician may find one or more
of the following Diagnostic Trouble Code (DTCs) in the PCM:
•
•
U0140 - Lost Communication With Body Control Module (BCM) (**VF**, LD, LX
Vehicles only).
P0606 - Internal Control Processor.
DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all engine 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.
If the customer describes a symptom/condition listed above or if the technician finds a
DTC, 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. Help using the wiTECH Diagnostic
Application for flashing control modules is available through the wiTECH Diagnostic
Application. For instructions select the “HELP” tab on 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. After PCM reprogramming, 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 them to be cleared.
NOTE: On LD vehicles only with a 2.65 rear axle (sales code DLC), and equipped
with Police Group equipment package (sales code AHB), the Transmission
Control Module (TCM) software must be up to date prior to performing the
“TCM Initialize EGS” procedure.
1. Verify the TCM is up to date. Refer to all applicable published service bulletins
regarding Transmission Shift Enhancements for detailed repair procedures and labor
times.
2. Using wiTECH, perform the “TCM Initialize EGS” procedure located in the TCM “Misc
Functions” menu.
POLICY:
Reimbursable within the provisions of the warranty.
