P" Range Test - Suzuki 2006 SX4 Service Manual

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.
