Condition
Some customers may comment that when driving short distances and/or slow speed
driving cycles, their vehicle experiences one or several of the following conditions within
the first 10 to 15 minutes of vehicle operation in extremely cold weather conditions (-18°C
or less / 0°F or less):
• Loss of power
• Hesitation on acceleration
• Stalling condition
• May also notice a Malfunction Indicator Lamp illuminated
• After driving for a period of time, the driveability issues seem to diminish.
This condition may also cause an increase in crankcase pressure, creating oil leaks at
seals and gaskets.
Technicians may find one or more of the following DTCs set:
• P0234
• P0236
• P0299
• P2227
• P00C7
Cause
This condition may be caused by ice accumulation in the charge air cooler (CAC),
restricting air flow to the throttle body.
Correction
If any of the above conditions are present, allow time for possible ice build up in the CAC
to melt by allowing the vehicle to thaw in a warm environment.
If there is a check engine light with a P0234 or P0299 DTC during cold weather driving,
refer to Turbocharger/Supercharger Boost Sensor Inspection below.
– Frozen oil/water contaminant in the Turbocharger Wastegate Regulator Solenoid Valve
(TCV) is often concurrent with vehicle operating conditions that cause CAC freezing. If
either DTC P0234 or P0299 is set, refer to PIP5812C for Turbocharger Wastegate
Regulator Solenoid Valve Inspection. Cleaning or replacing the TCV solenoid should
be performed in addition to CAC protection measures specified in this bulletin.
Follow the Service Procedure below once the vehicle has had time to thaw.

3. Allow time for any ice build-up to melt by placing
the sensor port down.
4. Clean the sensor with a clean towel.
5. Install the sensor. Refer to Turbocharger/
Supercharger Boost Pressure Sensor
Replacement in SI.
Engine Control Module Programming
Important: Updated Engine Control Module
calibration: The updated calibration will enable a
revised transmission shift pattern during cold weather
operation which does not use overdrive as frequently.
As a result, the customer may notice elevated engine
RPMs during highway operation. This operating mode
will reduce the potential for ice to build up inside the
charge air cooler, and the potential for setting P0299 or
P0234 diagnostic codes.
Caution: Before downloading the update files, be sure
the computer is connected to the internet through a
network cable (hardwired). DO NOT DOWNLOAD or
install the files wirelessly. If there is an interruption
during programming, programming failure or control
module damage may occur.
• Ensure the programming tool is equipped with the
latest software and is securely connected to the
data link connector. If there is an interruption
during programming, programming failure or
control module damage may occur.
• Stable battery voltage is critical during
programming. Any fluctuation, spiking, over
voltage or loss of voltage will interrupt
programming. Install a GM Authorized
Programming Support Tool to maintain system
voltage. Refer to www.gmdesolutions.com for
further information. If not available, connect a fully
charged 12V jumper or booster pack disconnected
from the AC voltage supply. DO NOT connect a
battery charger.
Bulletin No.: 22-NA-007
Follow the on-screen prompts regarding ignition
power mode, but ensure that anything that drains
excessive power (exterior lights, HVAC blower
motor, etc) is off.
• Please verify that the radio time and date are set
correctly before inserting USB drive into vehicle
for programming, otherwise an error will result.
• Clear DTCs after programming is complete.
Clearing powertrain DTCs will set the Inspection/
Maintenance (I/M) system status indicators to NO.
Important: The service technician always needs to
verify that the VIN displayed in the TLC left side drop
down menu and the top center window match the VIN
plate of the vehicle to be programmed prior to using
Service Programming System 2 (SPS2) for
programming or reprogramming a module.
• For the TLC application, service technicians need
to always ensure that the power mode (ignition) is
“ON” before reading the VIN from the vehicle’s
VIN master module and that they do not select a
VIN that is already in the TLC application memory
from a previous vehicle.
• If the VIN that shows up in the TLC top center
window after correctly reading the VIN from the
vehicle does not match the VIN plate of the
vehicle, manually type in the VIN characters from
the vehicle VIN plate into the TLC top center
window and use these for programming or
reprogramming the subject module with the
correct vehicle VIN and software and/or
calibrations.
• The Engine Control Module (ECM) is the master
module (for VIP vehicles) that TLC reads to
determine the VIN of the vehicle. If the VIN read
from the vehicle by TLC does not match the VIN
plate of the vehicle, the ECM also needs to be
reprogrammed with the correct VIN, software and
calibrations that match the vehicle’s VIN plate.
• The Body Control Module (BCM) is the master
module (for GEM vehicles) that TLC reads to
determine the VIN of the vehicle. If the VIN read
from the vehicle by TLC does not match the VIN
plate of the vehicle, the BCM also needs to be
reprogrammed with the correct VIN, software and
calibrations that match the vehicle’s VIN plate.
Caution: Be sure the VIN selected in the drop down
menu (1) is the same as the vehicle connected (2)
before beginning programming.
