Diagnostic Procedure

  1. If SIR Diagnostic System Check has been performed, go to next step. If SIR Diagnostic System Check has not been performed, go to SIR DIAGNOSTIC SYSTEM CHECK .
  2. Using scan tool, request SIR DTC display. If DTC B0101, B0102, B0104 or B0105 is current, go to step  10. If DTC B0101, B0102, B0104 or B0105 is not current, go to next step.
  3. Turn ignition off. If DTC B0100 is current, disconnect driver-side EFS harness connector. See ELECTRONIC FRONTAL SENSOR (EFS)  under REMOVAL & INSTALLATION. If DTC B0103 is current, disconnect driver-side EFS connector. If connector shows signs of damage or corrosion, go to next step. If connector is okay, go to step  5.
  4. If EFS side of connector is damaged, replace EFS. If harness side of connector is damaged, replace connector. See WIRE REPAIR . Go to step  11.
  5. Disconnect SDM connector. See Figure. If SDM connector or terminals show signs of corrosion, poor connections or other damage, go to next step. If SDM connector and terminals are okay, go to step  7.
  6. If SDM connector shows signs of damage or corrosion, replace connector. See WIRE REPAIR . Go to step  11. If SDM terminals show signs of damage or corrosion, go to step  12.
    NOTE: Use Digital Multimeter (J-39200) and Connector Test Adapter Kit (J-35616-A) or Flat WIre Probe Adapter Kit (J-42675) when performing electrical tests.
  7. If DTC B0100 is current, disconnect passenger-side EFS connector. If DTC B0103 is current, disconnect driver-side EFS connector. Inspect applicable circuits for an open or high resistance. If an open or high resistance is found and corrected, go to step  11. If an open or high resistance is not found, go to next step.
  8. Check for a short between applicable circuits. If a short is found and corrected, go to step  11. If a short is not found, go to next step.
  9. Turn ignition on. Check for a short to voltage in applicable circuits. If a short to voltage is found and corrected, go to step  11. If a short to voltage is not found and corrected, go to next step.
  10. If DTC B0102 or B0104 is current, replace passenger-side EFS. See ELECTRONIC FRONTAL SENSOR (EFS)  under REMOVAL & INSTALLATION. Go to next step. If DTC B0101 or B0105 is current, replace driver-side SIS. Go to next step.
  11. Reconnect all SIR components. Using scan tool, clear all SIR DTC's. Road test vehicle, then check for DTC's. If DTC's are retrieved, go to next step. If DTC's are not retrieved, system is normal.
  12. Replace SDM. See SENSING & DIAGNOSTIC MODULE (SDM)  under REMOVAL & INSTALLATION. Go to next step.
  13. Using scan tool, clear all SIR DTC's. Road test vehicle, then check for DTC's. If DTC's are retrieved, go to step  2. If DTC is not retrieved, system is normal.
