SYMPTOM/CONDITION:
The technician may find the following Diagnostic Trouble Code (DTC) set in the Powertrain
Control Module (PCM) memory:
•

**U0140 - Lost Communication With Body Control Module.**

Some customers may experience any of the following:
•
•
•
•

**2 - 1 downshift clunk or bump (JC vehicles).**
Long crank times when temperature is between -6°C and -3°C (20°F and 25°F) and
15°C and 18°C (60°F and 65°F).
Engine RPM fluctuation on closed throttle deceleration between 48 KPH and 32
KPH (30 MPH and 20 MPH).
Slightly elevated RPM (100 RPM) while driving slow or parking lot driving conditions
(JC vehicles).

Updating the PCM software will correct the conditions listed above.
DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all related systems are functioning as designed. If DTCs and/or
symptom/conditions other than the ones listed above are present, record them 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
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. 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.
