I pulled the cassette out and cleaned it but still have a flashing 19 and B2293. This points to driver airbag circuit. I'm guessing the cassette is just bad and need replacing. Any other ideas?

 

There are a few ways to check the circuit. I have an assortment of 2.2 Ohm resistors in the proper harness plug connectors that I substitute for a certain part of the circuit I am diagnosing. You can disconnect the driver's airbag assy and the connector on the lower column. You then use a meter to test the cancellation module continuity. DO NOT TEST WITH AIRBAG IN THE CIRCUIT!!!
You run the risk of deploying the airbag.

The best way is to use a diagnostic scanner that can access the SRS module (B Codes) and use the DATALOGGER to read the Ohms VIA the Module. DO NOT READ THE AIRBAG DIRECT!!

AutoEnginuity can do that. Obviously the dealer tools can.

 

The dealer showed 3.23 ohms on the driver airbag which is well above the 2.2 but does that mean it's the spiral cassette?
