Toyota Corolla (E120): On–vehicle inspection

1. Inspect pressure switch no.1.

  1. Magnetic clutch control: inspect pressure switch operation.
  1.  Set on the manifold gauge set.
  2.  Connect the positive (+) lead from the ohmmeter to terminal 4 and the negative (–) lead to terminal 1.
  3.  Check continuity between terminals when refrigerant pressure is changed, as shown in the illustration.

If operation is not as specified, replace the pressure switch.

  1. Cooling fan control: inspect pressure switch operation.
  1. Connect the positive (+) lead from the ohmmeter to terminal 2 and the negative (–) lead to terminal 3.
  2.  Check continuity between terminals when refrigerant pressure is changed, as shown in the illustration.

If operation is not as specified, replace the pressure switch.

2. Cooler compressor assy w/magnetic clutch

  1.  connect the positive (+) lead from the battery to terminal and the negative (–) lead to the body ground.
