and body ground.
Ok: resistance: 1 mw or higher
2 Check air bag sensor assy center

- clear the dtc stored in memory .
- turn the ignition switch to lock, and wait at least for 20 seconds.
- turn the ignition switch to on, and wait at least for 20 seconds.
- check the dtc .
Ok: dtc b0117/45 is not output.
Hint
