Inspection

INSPECTION PROCEDURE

  1. Connect recovery/recycling/recharging equipment (for HFC-134a) or manifold gauge.
  2. Start the engine, and set to the following condition.

Test condition                                           

  1. Maintain test condition until A/C system becomes stable. (Approximately 10 minutes)
  2. Check that test results of "recirculating-to-discharge air temperature" and "ambient air temperature-tooperating pressure" are within the specified value.
  3. When test results are within the specified value, inspection is complete.

    If any test result is out of the specified value, perform diagnosis by gauge pressure. Refer to HA "Symptom Table".
