Self-Diagnostic Precautions

  1. If distance from sonar road surface sensor to road surface is not within a 7.87-19.69" (200-500 mm) range, sensor will indicate a malfunction. Testing surface should be flat.
  2. Self-diagnostic indication on shock absorber actuators shows only abnormalities of the command signal from ECU to actuators. To test electrical circuit between ECU and actuators or to test actuators, perform FINAL CONFIRMATION ON SHOCK ABSORBER ACTUATOR. See Fig 9 and Fig 10 .
