In order to improve the security function against manipulation of the odometer reading, the rewrite procedure of odometer data will be changed starting with the M-MDS B-58 release in certain vehicles.
To enhance the Odometer Write security, a pair of passwords
called "Odometer Incode" and "Odometer Outcode" will be
necessary when rewriting the odometer data, after replacing
with a new unit. The Odometer Incode needs to be searched and
obtained from Mazda Service Support System (MS3) as well as the
Incode necessary for Immobilizer related
Mazda3 (07 to Present)
MX-5 (06 to Present)
All new model vehicles which will be released from now.
*Vehicles other than those above, rewriting odometer data is not supported.
