B1019 00

  1. Ignition ON, verify the scan tool End Model Part Number is correct for the vehicle.
    • If the part number is incorrect, reprogram the SDM.
    2. NOTE:
    • If not equipped with PPS, the scan tool parameter should display Not Present and the PPS indicator should not be present on the vehicle.
    • If equipped with PPS, the scan tool parameter should display Auto, Manual, or Auto + Man and the PPS indicator should be present on the vehicle.
  2. Observe the scan tool PPS Options parameter to determine how the vehicle PPS is currently configured in the SDM. Verify the actual vehicle equipment and the current configuration indicated by the scan tool parameter are the same.
    • If the original configuration does not match the actual vehicle equipment, reprogram the SDM with the correct configuration.
  3. Ignition OFF, disconnect the harness connectors at the SDM and verify the connector is in good condition and has no bent pins, terminals or shorting bars.
    • If damage is found, repair the bent pins, terminals or shorting bars as needed and perform the Setup New SDM procedure.
  4. Connect the harness connector at the SDM.
  5. Ignition ON, verify the scan tool System Configuration matches the actual components installed on the vehicle.
    • If the System Configuration does not match the actual components installed, reprogram the SDM with the correct components.
  6. Ignition ON, clear all PPS and SDM DTCs.
  7. Verify DTC B1019 does not set.
    • If DTC sets, replace the SDM.
