  2. Switch the ignition ON (engine off or on).
  3. Connect the negative (-) lead of the tester to body ground.
  4. By inserting the positive (+) lead of the tester into each climate control unit terminal, measure the voltage according to the terminal voltage table.
    • If there is any malfunction, inspect the parts under "Inspection item (s)".
      • If the parts under "Inspection item (s)" are found to be normal (except for terminal 2D), replace the climate control unit.
