Condition

Some customers may comment that the MIL is illuminated.
Some technicians may find one or more of the following DTCs set in the Engine Control
Module (ECM):
• P0071: Ambient Air Temperature Sensor Performance
• P1010: Engine Coolant Flow Control Valve Position Sensor Exceeded Minimum
Learning Limit
• P111E: Engine Coolant Temperature Sensor Not Plausible
• P14D9: NOx Sensor Exceeded Minimum Learning Limit Bank 1 Sensor 3
• P200A: Intake Manifold Runner Control Valve Performance
• P214E: Reductant Pump High Current

• P2384: Exhaust Gas Recirculation Differential Pressure Sensor Circuit Intermittent
• P24B0: Particulate Matter Sensor Circuit Low Voltage
• P2B60: Engine Coolant Flow Control Valve Position Sensor Circuit Performance
• P2C7A: NOx Catalyst Efficiency Below Threshold Bank 1 Catalyst 2

Cause

This condition may be caused by a software anomaly.

Correction

Verify if Service Update N192282970: Service Update – ECM and Reductant Control
Module (RCM) has been performed:
• If Service Update N1922282970 has NOT been previously performed, refer to Service
Update N1922282970 and no further action is required.
Note: ECMs that has been programmed prior to February 17, 2020 may not have all of
the latest software calibrations required to eliminate all the DTCs that set.
• If Service Update N1922282970 has been completed prior to February 17, 2020.
Reprogram the ECM as outlined in this bulletin to the latest software available.
• If DTC P24B0 is Active, replace the Exhaust Particulate Sensor.
If any of the above DTCs return after any of the procedures have been completed, refer to
SI for diagnosis and repair.

Service Procedure
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.
Important: Carefully read and follow the instructions
below.
• 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 12 V jumper or booster pack
disconnected from the AC voltage supply. DO
NOT connect a battery charger.
• Turn OFF or disable systems that may put a load
on the vehicles battery such as; interior lights,
exterior lights (including daytime running lights),
HVAC, radio, etc.
• Clear DTCs after programming is complete.
Clearing powertrain DTCs will set the Inspection/
Maintenance (I/M) system status indicators to NO.

of the bulletin.

1. Reprogram the ECM. Refer to K20 Engine Control
Module: Programming and Setup in SI. Modify as
required (e.g., select x module from the controller
screen. Then provide step-by-step instructions or
refer to SI procedure.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
