SERVICE INFORMATION

Attention:

If field action bulletin 43880-02 and 43190-01 must be completed on a vehicle, ensure field action bulletin 43190-01 is completed first. Engine control module (ECM) and starter damage can occur if 43190-01 is NOT completed first.
This service update includes vehicles in dealer inventory and customer vehicles that return to the dealership for any reason. This bulletin will expire at the end of the involved vehicle's New Vehicle Limited Warranty period.

Make	Model	Model Year		RPO	Description
Make	Model	From	To	RPO	Description
Cadillac	ATS	2016	2016	KL9	Start/Stop Engine Control Option

Involved vehicles are marked "open" on the Investigate Vehicle History screen in GM Global Warranty Management system. This site should always be checked to confirm vehicle involvement prior to beginning any required inspections and/or repairs.

Condition

On some 2016 model year Cadillac ATS, CT6, CTS, and Chevrolet Malibu vehicles equipped with a start/stop engine control option (RPO KL9), the system level interactions related to the transition of run/crank and accessory inputs to the engine control module (ECM) during a crank event are compromised. This results in communication issues between the ECM and the intelligent battery sensor. The check engine light will illuminate and the stop/start system is suspended while the fault is active, resulting in degraded fuel economy.

Correction

Inspect the ECM calibration version, and reprogram the ECM software calibration to the latest version as necessary.

PARTS

No parts are required for this repair.

* The 0.2 add time is to compensate for the duration of the 4 minute drive above 32 km/h (20 mph) to ensure the OAT is at the appropriate value prior to returning the vehicle to the customer.

SERVICE PROCEDURE

NOTE:

If you are attempting to reprogram the ECM for this bulletin, and get the warning you are attempting to program with the same calibration, this vehicle already has the latest calibrations. Stop the programming process at this point. Then please submit the warranty claim and make sure to close the open repair in IVH for this VIN.

NOTE:

Carefully read and follow the instructions below.

DO NOT attempt to order the calibration number from GM Customer Care and Aftersales. The calibration numbers required for this service procedure are programmed into control modules via a Multiple Diagnostic Interface (MDI) with the calibration update. If you cannot access the calibration, call the Techline Customer Support Center and it will be provided.
DO NOT program a control module unless directed to by a service procedure or a service bulletin. If the control module is not properly configured with the correct calibration software, the control module will not control all of the vehicle features properly.
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. When required install the EL-49642 SPS Programming Support Tool to maintain system voltage. 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.
During the programming procedure, follow the SPS prompts for the correct ignition switch position.
Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to NO.

CAUTION:

Install EL-49642 SPS programming support tool.
Access the Service Programming System (SPS) and follow the on-screen instructions.
Perform the SPS function K20 Engine Control Module - Programming and follow the on-screen instructions.
Clear DTCs after completing the Programming procedure. DTC P16DC may have been set prior to performing the Programming procedure.
NOTE:
If the vehicle fails to start during Setup, perform the SPS Function Immobilizer Learn and follow the on-screen instructions.
Perform the SPS function Engine Control Module - Setup and follow the on-screen instructions, if available.
Clear DTCs after completing the Setup procedure.
Disconnect EL-49642 SPS programming support tool.
NOTE:
The system has lost the Outside Air Temperature (OAT) value and it must be relearned after reprogramming the ECM (ATS and CTS only).
To relearn the OAT, the vehicle must be driven above 32 km/h (20 mph) for 4 minutes. The OAT reading should then agree with the ambient temperature.

NOTE:

If you cannot access the calibration, call the Techline Customer Support Center and it will be provided.

DEALER RESPONSIBILITY
