SJ,
There's no need to start with SRS ECU replace but first you're to doublecheck and ensure that LH knock sensor has a strong ground (electrical to body) connection. Probably that nut that holds the sensor is loosen or such.

Saab Service Manual 8:6 Airbag M90+, p/no # 340257
Page 33, Test procedure 5
Fault code 0F: LH front sensor, resistance to earth 3 ohm or higher
Fault code 10: RH front sensor, resistance to earth 3 ohm or higher

Undo the securing screws for the front sensor. Clean the contact surfaces between the sensor and its bracket on the body, and also the thread on the captive nut.
Lubricate the thread and cavity in the captive nut.
Lubricate the threads on the new securing screws and fit the screws.
Use lubricant, part no. 45-3007309, or Ford Motorcraft silicone dielectric compound or an equivalent lubricant with good electrical conductivity.
Delete the fault codes and wait, with ignition on, for at least 35 seconds.
Check that the code has been cleared.

Best luck,
Zig

P.S.
SRS ECU is to be reset with either Tech2 tool + SRS-Tech2 adapter or with special SRS tester in order to wipe out DTC. SRS Diagnostic Trouble Codes are not deleted if SRS is just powered down.
