The dealer must choose which failure code to use depending on if this is a Rapid Service Update
(RSU) or Technical Service Bulletin.
● The “RF” failure code is required for essential module flash/reprogramming and can only be used after
confirmation that the VIN is included on the RSU.
● The failure code “RF” (Required Flash) can no longer be used on Technical Service Bulletin flashes. The
“RF” failure code must be used on an RSU.
● If the customer’s concern matches the SYMPTOM/CONDITION identified in the Technical Service Bulletin,
failure code CC is to be used. When utilizing this failure code, the 3C’s must be supplied.
DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in DealerCONNECT/
Service Library, verify all related systems are functioning as designed. If Diagnostic Trouble Codes (DTCs) or
symptom conditions, other than the ones listed above are present, record the issues on the repair order and
repair as necessary before proceeding further with this bulletin.
If a customers VIN is listed in VIP or your RSU VIN list, perform the repair. If any vehicle not on the VIN list
exhibits any of the symptom listed above in the customer symptom section, perform the Repair Procedure.

REPAIR PROCEDURE:
WARNING!
● Before performing the software reprogramming, it is necessary to make the vehicle safe.
● When performing repairs that directly involve or imply possible contact with live high voltage
components/systems, the technician must ensure that the power supply of the high-voltage system
is disconnected throughout the operation.
● Only specifically trained technicians qualified to perform repairs on vehicles with high voltage
systems under current national laws/regulations are authorized to work on the vehicle.
● Before performing any diagnostic repair work on the vehicle, carefully read and comply with
the general instructions for working safely on hybrid/electric vehicles and use suitable general
equipment and Personal Protective Equipment (PPE).
● The vehicle must not be connected to a high voltage charger when performing software updates.
NOTE: ● Install a 12 volt battery charger to ensure sufficient battery voltage which can also support
50-60 amps during the flash process.
● The remote battery posts (jump posts) under the hood may be used to connect a 12 volt
battery charger to eliminate the need to remove the battery.
● If this flash process is interrupted/aborted, the flash should be restarted.

CAUTION!
● To lower the risk of failure modes prior to the flash update, do not open trunk, frunk or passenger
door without first opening the driver door before performing this Repair Procedure. This process
will not need to be performed after the flash update has been completed.
● Minimize on-site vehicle movements and ignition cycles where possible before performing this
Repair Procedure.
● If the vehicle has recently been driven, on a test drive for example, the vehicle needs to sit and
cool down for one hour before performing this update. Failure to allow the vehicle to cool down
may cause in substantial consequential damage to occur. Pulling the vehicle into the bay does not
justify the one hour cool down.
1. Is the vehicle on the RSU VIN list?
● YES >>> Proceed to Step 2.
● NO >>> Proceed to Step 3.
2. Does the IDCM, BPCM, MCP A, MCP B and the EVCU have the latest software already installed?
CAUTION!
There will not be a lightening bolt present for the BPCM to be reprogrammed due to some vehicles
requiring two updates. The software level must be inspected before reprogramming to ensure the
proper update steps are followed.
● YES >>> This bulletin has been completed, use inspect **(18-19-17-90)** to close the active RSU.
● NO >>> Proceed to Step 3.
3. Remove the front storage bin. Refer to the detailed service procedures available in DealerCONNECT/
Service Library under: Service Info> 23 - Body / Exterior / Bin, Storage / Removal.
NOTE: The cooling fan must be disconnected to prevent it from powering on, which may interrupt/
abort the flash process.
4. Disconnect the cooling fan wire harness connector Fig. 1.

CAUTION!
There will not be a lightening bolt present for the BPCM to be reprogrammed due to some vehicles
requiring two updates. The software level must be inspected before reprogramming to ensure the
proper update steps are followed.
7. Inspect the software level on the BPCM by going into the "Flash" tab and compare to what software is
available Fig. 4.

**Two Step Software Level AQ And AR Screen**
CAUTION!
If the BPCM is already at the **AQ** level, the module must be reprogrammed to the AF level. Do
not over flash at the **AQ** level to get to the **AR** level.
8. Is the BPCM software at the **AQ** level?
● YES >>> Proceed to Step 10.
● NO >>> Proceed to Step 9.
9. Reprogram the BPCM to the **AQ** level. Then proceed to Step 10.

Functions’ menu for the BPCM.
27. Clear DTCs, place the ignition in the "Off" position and allow the vehicle to go to sleep. This will take
approximately six minutes then proceed to Step 28.
NOTE: For the six-minute sleep cycle to be successful, the micropod must be disconnected
and the ignition must be set to OFF prior to starting the sleep cycle. Additionally, all
accessories, lights and electrical units must be turned off, and hood, trunk and all doors
must be closed with no one inside the vehicle. During this sleep cycle, the vehicle may
present IPC warnings, chimes and other DTCs.

● NO >>> Proceed to Step 36.
34. Using wiTECH, perform a "Wheel End Disconnect Position Learn" routine. This routine is located in
the ’Misc Functions’ menu for the EVCU.
NOTE: If the Wheel End Disconnect Position Learn routine is not successful, roll the vehicle
slightly forward so that the wheel end disconnect actuators can align on the spline before
attempting to perform the routine again.
