DTC B2795/99 Unmatched Key Code
This DTC is output when an unregistered key is inserted. When this DTC is output, delete DTC and insert
the key that a customer keeps to check that B2795 is output.
When a key that outputs B2795 is found, register this key. When B2795 is not output, there is a possibility
that the unregistered key has been inserted before. (ECM is normal.)
Inquire of a customer about the condition of using the system to find the cause of the trouble.
(Example: Another key has been inserted, etc.)
