WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

If the malfunctioning part is detected in the communication line, before disconnecting the related connector for inspection, press the connector in the connection direction to verify that there is no looseness or disconnection.
When disconnecting the connector, verify that there is no damage, deformation, or corrosion of the connector terminals.

Verify the CAN system-related module DTCs and the failed module on the M-MDS screen.
Refer to "DTC Output Pattern and Malfunctioning Part " and find the area linked from the malfunctioning part.
