SAE J1850

Access to vehicle networks for onboard-diagnostics (OBD)

The launch of OBD - in the US well before Europe - led to standardized access of vehicle networks. In the US, the J1850 bus, standardized by the SAE, was used for this purpose.

After the bus was used for many years in its designs for Ford and GM, it has now been widely replaced by the CAN bus.
