Caution
l While testing refrigerant pressure switch No.2, care-
fully note the high-pressure side refrigerant pres-
sure. If the pressure increases above 1,766 kPa (18
kg/cm2, 256 psi), stop the testing. _,
7. Disconnect the condenser fan connector.
8. Run the engine at 2,000 rpm, and operate the air condi-
tioner at maximum cooling position.
9. Check that the refrigerant pressure switch turns on when
the high-pressure side refrigerant pressure increases above
1,570 f 98 kPa (16 f 1 kg/cm2, 228 f 14 psi).
IO. If not as specified, replace the switch together with cooler
pipe No.2. (Refer to page U-54.)

Precautions when servicing electrical system
l Note the following items when servicing the electrical system.
l Do not alter the wiring or electrical equipment in any way as this may damage the vehicle or cause a fire
due to shorting or overcapacity of a circuit.
l Always disconnect the negative (- ) battery cable first and 0 Replace blown fuses with ones having the same designated

Zaution
l Be sure that the ignition and other switches are OFF
before disconnecting or connecting the battery
terminals.
Failure to do so may damage the semi-conductor
components. Caution l Replacing a fuse with one of a larger capacity than
designated may damage components or cause an electrical
fire.
