This PI has been updated to include an updated Warranty Information. Please disregard PIC6140A.


A dealer or customer may notice a red LED and DTC B2455 setting current in the VCIM after performing Canada upgrade bulletin 15-08-44-001.

When placing calls or connecting to OnStar, the person on the other end is able to hear the caller clearly.



  1. It has been found that a short between the audio drain wire and microphone drain wire will cause this concern.
  2. Pull back the tape at X2 of the VCIM far enough to see where the bare wires are covered.
  3. Tape the bare wires individually to prevent them from shorting. Then tape the harness back up.
