Saab 9000 3.0L V6 (1995 – 1997) OBD1 Codes

Model:	9000 3.0L V6
Year:	1995-97
Engine identification:	8308I
System:	Motronic 2.8.1

General information

Trouble codes are displayed by the malfunction indicator lamp (MIL).
The ECM fault memory can also be checked using diagnostic equipment connected to the data link connector (DLC).

Accessing -flash codes

Ensure ignition switched OFF.
Jump data link connector (DLC) terminal 2 (1995) [1] or terminal 6 (1996->) [2] and ground with a switched lead – contacts normally open.
Switch ignition ON.
Set switch to ON [1] or [2]
Check that MIL flashes.
Trouble codes are displayed as a two digit number with a 3 second interval between each separate code.
Count MIL flashes. Note trouble codes. Compare with trouble code table.
For example: Trouble code displayed: 31 – intake air temperature (IAT) sensor [3].
Trouble codes will continue to be displayed if data link connector (DLC) terminal 2 or terminal 6 switched to ground.

Erasing – flash codes

Diagnostic equipment required to erase data from ECM fault memory.
