Cause

Engineering is currently investigating the cause of these diagnostic trouble codes.
It is believed they are faults with the electrical circuit that may not self-heal.

Correction:
If you have a Car located in Southern Michigan setting the P0A3F, please call Technical Assistance for Possible
engineering interaction.
Do not Clear any codes
Please do not Continue with this PI unless instructed by Technical Assistance.
For vehicles NOT located in Southern Michigan, Please perform the Following.
Using SI DocID 4583435 as a guide, inspect the terminals at connector X1 at the T6 Power Inverter Module
and the X2 connector at the T12 Transmission Assembly.
Pay special attention to the Diagnostic Aids in SI DocID 4583435. Look for any backed out, bent, or spread
terminals on both sides of the connector.
1. If a concern is found with a terminal, please contact Technical Assistance and provide a clear picture
of the issue. Replace the under-hood "engine" harness and the mating component of the terminal
concern.
If there are no terminal problems found, please replace the power inverter module, the under-hood
"engine" harness, and the transmission. This is for protection of the customer for any circuit imperfection
that could cause these DTCs while the engineering investigation is in progress. These components are not
on TAC restriction.
When preparing the parts for Return
Please protect all of the T6 X1 and T12 X2 connector ends for warranty parts return analysis. Submit labor
