Parameter | System State | Expected Value | Definition |
|---|---|---|---|
Operating Conditions : Ignition ON | |||
Active Switch | -- | Enabled | The scan tool displays Enabled or Disabled. This is the state of the SIR active switch. |
Active Switch | -- | Learned | The scan tool displays Learned or Unlearned. Learned is displayed if the SIR learned the active switch. |
Battery Voltage Signal | -- | Varies | The scan tool displays 0-20 volts. This is the system voltage measured by the SDM between the battery input and ground. |
Deployment Loop 1-12 | -- | Enabled | The scan tool displays Enabled or Disabled. This is the state of the SIR loop. |
Deployment Loop 1-12 | -- | Learned | The scan tool displays Learned or Not Learned. Learned is displayed if the SIR has that number loop learned. |
Driver Seat Belt Switch | -- | Unbuckled | The scan tool displays Buckled or Unbuckled. This is the state of the driver seat belt. |
Driver Seat Belt Type | -- | Varies | The scan tool displays Switch or Sensor. The scan tool displays whether the driver seat uses a switch or a sensor for the seat belt buckle. |
Driver Seat Position Sensor | -- | Enabled | The scan tool displays Enabled or Disabled. This is the state of the driver seat position sensor. |
Driver Seat Position Sensor | -- | Learned | The scan tool displays Learned or Unlearned. Learned is displayed if the SIR learned the driver seat position sensor. |
Driver Seat Position Sensor | -- | Varies | The scan tool displays whether the driver seat is in the Forward or Rearward position to determine if the airbag should activate single or dual stage deployment as necessary. |
Impact Sensor 1-6 | -- | Enabled | The scan tool displays Enabled or Disabled. This is the state of the sensor. |
Impact Sensor 1-6 | -- | Learned | The scan tool displays Learned or Unlearned. Learned is displayed if the SIR has that sensor learned. |
Loop 1-12 Type | -- | Varies | The scan tool displays Not Used, LF Stage 1, RF Stage 1, LF Stage 2, RF Stage 2, LF Preten., RF Preten., LF Side Bag, RF Side Bag, Lt. Roof Stage1, Rt. Roof Stage1, Lt. Roof Stage2, Rt. Roof Stage2, Lt. Roof Stage3 or Rt. Roof Stage3. This is the type of loop. |
Passenger Seat Belt Switch | -- | Unbuckled | The scan tool displays Buckled or Unbuckled. This is the state of the passenger seat belt. |
PPS Options | -- | Varies | The scan tool displays Not Present, Manual, Auto or Auto. + Man. This is the current enabled option of the passenger presence system. |
PPS Status | -- | Enabled | The scan tool displays Enabled or Disabled. This is the state of the passenger presence system. |
PPS Status | -- | Learned | The scan tool displays Learned or Unlearned. Learned is displayed if the SIR has learned the passenger presence system. |
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 BCM and the SDM. If the Status is other than Valid the SDM will not allow activation and should set a DTC. |
Psgr. Seat Belt Sensor | -- | Enabled | The scan tool displays Enabled or Disabled. This is the state of the passenger seat belt sensor. |
Psgr. Seat Belt Sensor | -- | Learned | The scan tool displays Learned or Unlearned. Learned is displayed if the SIR learned the passenger seat belt sensor. |
Psgr. Seat Belt Sensor | -- | Varies | This displays mA. This is the amount of current supplied to the passenger seat belt sensor. |
Psgr. Seat Belt Type | -- | Varies | The scan tool displays Switch or Sensor. The scan tool displays whether the passenger seat uses a switch or a sensor for the seat belt buckle. |
Psgr. Seat Position Sensor | -- | Enabled | The scan tool displays Enabled or Disabled. This is the state of the passenger seat position sensor. |
Psgr. Seat Position Sensor | -- | Learned | The scan tool displays Learned or Unlearned. Learned is displayed if the SIR learned the passenger seat position sensor. |
Psgr. Seat Position Sensor | -- | Inactive | The scan tool displays Rearward or Forward. The scan tool displays whether the passenger seat is in the Forward or Rearward position to determine if the airbag should activate single or dual stage deployment as necessary. |
Received Primary Key | -- | Varies | The scan tool displays what the SDM received from the BCM as the primary key. The SDM then compares it to what it has stored to determine the Primary Key Status. The SDM Primary Key and Received Primary Key should match. |
Received VIN Digits 2-5 | -- | Varies | The scan tool displays the Secondary Key which includes digits 2 though 5 of the VIN that the BCM sends to the SDM. |
Received VIN Digits 6-7 | -- | Varies | The scan tool displays the Secondary Key which includes digits 6 and 7 of the VIN that the BCM sends to the SDM. |
Rollover Sensor | -- | Enabled | The scan tool displays Enabled or Disabled. This is the state of the rollover sensor. |
Rollover Sensor | -- | Learned | The scan tool displays Learned or Unlearned. Learned is displayed if the SIR learned the rollover sensor. |
Run/Crank | -- | Active | This displays volts. This is the current power mode of the SDM. |
Secondary Key Status | -- | Valid | The scan tool displays Unknown, Valid or Invalid. This determines if the VIN stored in SDM memory matches what is stored in the BCM. |
Sensor 1-6 Type | -- | Varies | The scan tool displays Not Used, EFS LF, EFS Center, EFS RF, SIS Left Row 1, SIS Right Row 1, SIS Left Row 2 or SIS Right Row 2. This is the type of SIR sensor. |
SDM Primary Key | -- | Varies | The scan tool displays the primary key that the SDM has stored to memory. |
SIR Warning Indicator | -- | Off | The scan tool displays On or Off. This is the status of the SIR warning indicator. |
Scan Tool Output Control | Description |
|---|---|
Setup New SDM | This output control is used to set up a new SDM. |
Setup SDM Primary Key in BCM | This output control is used to set up a new SDM primary key in the BCM. |
