Circuit/System Verification

NOTE: DTC B1019 can set after the inflatable restraint sensing and diagnostic module has been replaced and/or reprogrammed before the setup procedure is completed. The setup procedure cannot be completed if DTC B1019 is set as current or history. If a short or open is detected in a deployment circuit prior to the setup procedure being performed, the inflatable restraint sensing and diagnostic module will set DTC B1019.
  1. Vehicle in Service Mode.
  2. Verify no other Inflatable Restraint Sensing and Diagnostic Module DTCs are set.
    • If no other inflatable restraint sensing and diagnostic module DTCs are set 
  3. Verify the impact sensors called out in the scan tool data list match the number of actual impact sensors installed on the vehicle.
    • If the number of impact sensors do not match 
    1. Verify the correct Inflatable Restraint Sensing and Diagnostic Module calibration file is loaded in the inflatable restraint sensing and diagnostic module.
      • If the inflatable restraint sensing and diagnostic module calibration file is correct and the vehicle contains an incorrect number of sensors, identify which sensors are missing to make the vehicle match the inflatable restraint sensing and diagnostic module impact sensor calibration scan tool data list.
      • If the calibration file is incorrect
    2. Reprogram the Inflatable Restraint Sensing and Diagnostic Module. Refer to Inflatable Restraint Sensing and Diagnostic Module Programming and Setup
    • If the number of impact sensors match 
  4. Verify the enabled deployment loops called out in the scan tool data list match the deployment loops installed on the vehicle.
    • If the number of enabled deployment loops do not match 
    1. Verify the correct Inflatable Restraint Sensing and Diagnostic Module calibration file is loaded in the inflatable restraint sensing and diagnostic module.
      • If the inflatable restraint sensing and diagnostic module calibration file is correct and the vehicle contains an incorrect number of loops, identify which deployment loops are missing to make the vehicle match the inflatable restraint sensing and diagnostic module impact sensor calibration scan tool data list.
      • If the calibration file is incorrect
    2. Reprogram the Inflatable Restraint Sensing and Diagnostic Module. Refer to Inflatable Restraint Sensing and Diagnostic Module Programming and Setup
    • If the number of enabled deployment loops match 
  5. Verify a passenger presence system is equipped on the vehicle.
    • If a passenger presence system is not equipped on the vehicle 

      Replace the K36 Inflatable Restraint Sensing and Diagnostic Module.

    • If a passenger presence system is equipped on the vehicle 
  6. Verify the passenger presence enable status called out in the scan tool data list is enabled.
    • If the passenger presence is enabled 
  7. Verify the passenger presence learn status called out in the scan tool data list is learned.
    • If the passenger presence learn status is not learned 
    1. Verify the scan tool can communicate with the passenger presence system.
      • If the scan tool communicates
    2. Vehicle OFF, disconnect the scan tool, wait two minutes.
    3. Vehicle in Service Mode, verify DTC B1019 is not set as current.
      • If the DTC is not set as current
    4. All OK.
    • If the passenger presence learn status is learned 
  8. Replace the K36 Inflatable Restraint Sensing and Diagnostic Module.
