Line Pressure Test - Suzuki Grand Vitara 2011 Manual

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 against wheels.
2) Remove fluid pressure check hole plug bolt.
3) Attach oil pressure gauge to fluid pressure check hole in transmission case.
Special tool
(A): 09925–37811–001
CAUTION
!
After attaching oil pressure gauge, check that no fluid leakage exists.
4) Depress foot brake fully, run engine at idle and stall then check fluid pressure in "D" or "R" range.
CAUTION
!
• Do not continue running engine at stall speed longer than 5 seconds.
• After performing line pressure test, be sure to leave engine running at idle for longer than one
minute before performing another line pressure test.
