id092000031100

Note

•  The CMU has stored vehicle specification information.

•  A new CMU does not have any stored vehicle specification information.

•  When the ignition is switched ON (engine off or on) after replacing the CMU, the unit reads and stores the vehicle specification information sent via CAN communication from the instrument cluster.

•  The Bluetooth^® pairing information stored in the CMU cannot be written to a new CMU. Therefore, the Bluetooth^® pairing information will be eliminated if the CMU is replaced. Before replacing the CMU, explain to the customer that the Bluetooth^® pairing resetting is required.
