Related catalog identifier
The catalog also lists 89663-0K210-B. The B suffix distinguishes that entry from the base identifier, but the catalog name does not explain whether it denotes a stock or modified variant or identify a specific change.
An engine control module generally uses calibration data to manage engine operation, but that general role does not establish what this particular revision changes. The full identifier, including any suffix, is therefore important when comparing catalog records.
