If the RCM airbag computer module is removed or disconnected. Try not to move the vehicle or turn ignition on. Keep battery terminals disconnected while the RCM is out of the vehicle to avoid OCSM calibration. Because it may store code B00A0 in the RCM/OCSM. Connect IDS/VCM or other diagnostic scan tool to the data link connector under the drivers side of the dash. Clear all codes from the RCM and OCSM, then access the OCS reset, and press the button on the screen. It will then show on the screen if it was successful or not. This is very common, most of the time you dont need to replace OCSM sensor. You will need to initialize/calibrate it. ## **OCSM Calibration** In the scan tool: (depending on a scan tool options may vary) 1. Go to SRS Airbags menu 2. Select sub menu: Occupant / OPDS / Weight Sensor 3. Select option: Zero out weight /  Initialize / Calibrate Previous Post ###### [Nissan SRS Code B1425 Rear Collision Detection](https://blog.myairbags.com/nissan-srs-code-b1425-rear-collision-detection) Next Post ###### [New motorized seat belts with seat belt module.
