J1587 is an automotive diagnostic protocol standard developed by the Society of Automotive Engineers (SAE) for heavy-duty and most medium-duty vehicles built after 1985. The J1587 protocol uses different diagnostic connectors. Up to 1995, individual OEMs used their own connectors. From 1996 to 2001, the 6-pin Deutsch was standard. Beginning in 2001, most OEMs converted to the 9-pin Deutsch. Some OEMs still use the 6-pin Deutsch.
The pinout for the 9-pin connector is:
| PIN | SIGNAL |
| A | Ground |
| B | Unswitched +12 VOLTS |
| F | J1708Datalink (+) |
| G | J1708Datalink (-) |
The pinout for the 6-pin connector is:
| Pin | Signal |
| A | J1708Datalink (+) |
| B | J1708Datalink (-) |
| C | Unswitched +12 VOLTS |
| E | Ground |
J1708 makes up the datalink and physical layer that supports J1587.
