SAE J2190

Last reviewed 2026-08-31

Manufacturer-enhanced OBD services above the J1979 set. Service 0x22 on Ford/GM-style enhanced OBD is defined here — not ISO 14229 UDS 0x22.

Scope. Enhanced OBD on some North-American and related ECUs.

Catalog relevance: do not confuse J2190 Mode 22 with UDS 0x22.
