DTC B1448: OC Passenger Sensor Mat Defect: Troubleshooting
WARNING: This page is about a different car, the 2008 Suzuki Reno, 2008 Suzuki Forenza, 2007 Suzuki Reno, and 2007 Suzuki Forenza. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
The Sensing and Diagnostic Module (SDM) can maintain sufficient voltage to deploy the airbags and pretensioners for 1 minute after the ignition is OFF and the fuse has been removed. If the airbags and pretensioners are not disconnected, do not begin service until 1 minute has passed after disconnecting power to SDM. Otherwise, injury could result.
WARNING:
During service procedure, be very careful when handling the SDM. Never strike or jar the SDM. Never power the Supplemental Inflatable Restraints (SIR) when the SDM is not rigidly attached to the vehicle. All SDM mounting bolts must be carefully tightened, and the arrow on the SDM must be point toward the front of the vehicle to ensure proper operation of the SIR. The SDM could be activated if it is powered when it is not rigidly attached to the vehicle, resulting in unexpected deployment and possible injury.
