Both DTC B0086 and B0087 are set

  1. Ignition OFF. Disconnect the X2 harness connector at the K36 Inflatable Restraint Sensing and Diagnostic Module. It may take up to 2 min for all vehicle systems to power down.
  2. Test for greater than 50k Ω between each signal circuit listed below and ground:
    • Right front signal circuit - terminal 22 X2
    • Left rear signal circuit - terminal 27 X2
    • If 50k Ω or less 
    1. Disconnect the harness connector at the B63 Side Impact Sensor that failed the test.
    2. Test for infinite resistance between the signal circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance, replace the B63 Side Impact Sensor.
    • If greater than 50k Ω 
  3. Ignition ON.
  4. Test for less than 1 V between the signal circuit terminals listed below and ground:
    • Right front signal circuit - terminal 22 X2
    • Left rear signal circuit - terminal 27 X2
    • If 1 V or greater 
    1. Ignition OFF. Disconnect the harness connector at the B63 Side Impact Sensor that failed the test. Ignition ON.
    2. Test for less than 1 V between signal circuit and ground.
      • If 1 V or greater, repair the short to voltage in the circuit.
      • If less than 1 V, replace the B63 Side Impact Sensor.
    • If less than 1 V 
  5. Ignition OFF, reconnect all harness connectors, press in the CPA (if equipped) until an audible and/or tactile click is heard.
  6. Ignition ON, clear DTCs. Operate the vehicle within the Conditions for Running the DTC.
  7. Verify the DTC does not set.
    • If the DTC sets 

      Replace the K36 Inflatable Restraint Sensing and Diagnostic Module.

    • If the DTC does not set 
  8. All OK.
