Service bulletin SA-022-26

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

MDARS II Record on Behavior (RoB codes). DESCRIPTION X-CODES – Record on Behavior (RoB) In the new CX-5, only certain control modules use Record on Behavior (RoB). (Some modules, such as the 7G transmission, record control information as “Operation History (DID)” instead of RoB.) DTC Format Change Some Diagnostic Trouble Codes (DTCs) have been expanded from 5 digits to 12 digits. Example: Current code: U2701:89-A0 New code: XU2050:55-B0 Display on MDARS II Some DTCs are displayed on MDARS II health check as shown in the table below. Meaning of the “X” Prefix The “X” in the upper digit (first character) of the DTC means: “It is not an error; it is just information.” to assist with diagnostic troubleshooting.
