Parameter | System State | Expected Value | Definition |
|---|---|---|---|
Operating Conditions : Ignition ON | |||
Battery Voltage Signal | -- | Varies | The scan tool displays 0-20 volts. This is the system voltage measured by the PPS between the battery input and ground. |
Passenger Classification | -- | Empty | The scan tool displays Unknown, Calibrating, Empty Seat, Small 1, Small 2, Large or Re-Zero. The scan tool displays the calculated seat occupant status or need to re-zero. |
Passenger Status | -- | No Info | The scan tool displays No Info., Valid, Invalid Class., Invalid Pos., Invalid Data or Inval. Class & Pos. The scan tool displays the calculated seat occupant status including relationship to seat position. |
Power Mode | -- | Run | The scan tool displays Off, Accessory, Run or Crank Request. The scan tool displays the current vehicle power mode. |
PPS Enable Status | -- | Enabled | The scan tool displays Disabled or Enabled. The scan tool displays the current status of the PPS system. This information is sent to the SDM for deactivation of the deployment loops related to the passenger airbags. PPS Enable Status and SDM Enable status should match. |
PPS Fault Status | -- | No Fault | The scan tool displays No Fault, Plant Mode, Fault, Mismatch or Test Enable. The scan tool displays the current condition of the PPS system to determine if the SDM or PPS is causing the PPS Disabled condition. |
PPS Primary Key | -- | Varies | The scan tool displays primary key that the PPS has stored to memory. |
Pressure Sensor | -- | Varies | The scan tool displays the voltage determined by the weight/position of the seat occupant. |
Primary Key Status | -- | Valid | The scan tool displays Unknown, Valid or Invalid. The scan tool displays the status of the primary key based on the comparison between the SDM and the PPS. If the Status is other than Valid the PPS will not allow activation and should set a DTC. |
Received Primary Key | -- | Varies | The scan tool displays what the PPS received from the BCM as the primary key. The PPS then compares it to what it has stored to determine the Primary Key Status. The PPS Primary Key and Received Primary Key should match. |
Seat Belt Tension Sensor | -- | Varies | The scan tool displays voltage which is used to determine whether a child infant seat is mounted in the passenger seat or not. |
SDM Enable Status | -- | Enabled | The scan tool displays the current status of the PPS system within the SDM. When disabled, SDM will default to deactivate the deployment loops related to the passenger airbags. PPS Fault Status and SDM Fault status should match. |
