Scan Tool Method
- Attach clamp-on thermocouple to liquid line, as close to condenser outlet as possible. Attach scan tool to Data Link Connector (DLC), located right of steering column, under instrument panel. See Figure.
- Set parking brake, and place transaxle in Park position. Start engine and allow to idle. Set A/C controls to outside air, panel mode, full cool, and high blower speed. Turn A/C on, and open windows. Operate system for a few minutes to allow system to stabilize.
- Place cardboard over front grille area, to block airflow through part of condenser, to set A/C pressure to 260 psi (18.3 kg/cm2 ). This will stop cooling fans from alternating speeds and maintain constant pressure.
- Scan tool will automatically calculate system charge. Depending on system charge condition, corrections are made 2 ounces at a time. Each time a correction is made, recheck readings to ensure proper charge. Total system refrigerant capacity is 28 ounces.
