Line Pressure Test

Purpose of this test is to check operating conditions of
each part by measuring fluid pressure in fluid pressure
line.
Line pressure test requires following conditions.
• Automatic fluid is at normal operating temperature (70
– 80 °C / 158 – 176 °F).
• Fluid is filled to proper level (between FULL and LOW
on dipstick).
• Air conditioner switch is turned OFF.
1) Apply parking brake securely and place chocks
