The technician observed the IDCM is setting DTC B22A9-42-ECU Internal Performance-General Memory Failure Integrated Dual Charge (IDCM) Discussion: Engineering is aware of the concern and is currently working on a software update for the IDCM. If the vehicle has the above-described complaint; the DTC can be cleared allowing the vehicle to operate and charge as expected. The service update is expected by the end of September, the field will be notified when the update becomes available. Do not replace any parts the replacement parts will perform the same. Repair : Clear the DTC. It will allow the vehicle to operate and charge as expected. Do not replace the IDCM.
