INSPECTION

D-sensor (LH)

D-sensor (LH) Inspection

  1. 1
    Disconnect the negative battery cable.
  2. 2
    Remove the knee protector, and disconnect the clock spring connectors (Orange and blue).

  3. 3
    Remove the bolts and the relay box.
  4. 4
    Disconnect the D-sensor (LH) connector.
  5. 5
    Measure resistance between the terminals of the sensor connectors.
    Do not connect an ohmmeter to the harness side connector. Connect the ohmmeter to the sensor side connectors only.
    Wire harness section showing two connectors labelled 'a (BLUE)' and 'b (ORANGE)' with an ohmmeter connected between terminals a and b on the sensor side to measure resistance.
