DESCRIPTION

Some customers may complain that Mazda Connect does not start (blank screen) or that it takes a long time to restart/reboot after starting the vehicle. This is caused by the initialization process with the CMU failing at startup due to a defective circuit board element. To eliminate this concern, the internal hardware (DRAM) of the CMU has been improved.

Customers having this concern should have their vehicle repaired using the following repair procedure.

REPAIR PROCEDURE

  1. Verify the customer concern
  2. Check the CMU Part No. and Serial No. of the CMU. If applicable, replace the CMU according to the procedure in MGSS.
    NOTE: Refer to instructions below on how to indicate the Part No. and Serial No.  of the CMU.
