REDUCING PRESSURE ADJUSTMENT 23100180033
WHEN SCAN TOOL IS NOT USED 1. Remove parts up to the oil filter in the same wa y as
for adjustment of the line pressure. The valve body need
not be removed.
2.Tune the adjustment screw of the lower valve body a nd
adjust so that the reducing pressure is the standard value.
When the adjustment screw is turned clockwise, the reduc-
ing pressure decreases; when it is turned counterclock-
wise, it increases.
NOTE
When adjusting the reducing pressure, aim for the c enter
value
(60 psi)] of the standard value allowance.
Standard value: 415-435 psi)
Oil pressure change for each turn of adjustment,
screw: 45
(6.5 psi)
3. Install the oil filter and oil
in the same way as for
adjustment of the line pressure.
4. Perform the oil pressure test. Readjust if neces sary.
WHEN SCAN TOOL IS USED 1. Use the scan tool to force-actuate the pressure control
solenoid valve to 50
duty, and measure the
brake apply pressure at that time. If the brake
apply pressure is not within the standard value, ad just
using the reducing pressure adjustment screw.
Standard value:
(36-44 psi)
Oil pressure change for each turn of adjustment
screw: 22
(3.2 psi)
2. Check to be sure, after completing this adjustme nt, that
the reducing pressure is within the range of
(51-68 psi).
Caution
The adjustment should be made at an oil temperature
of
If the adjustment is made at an oil temperature tha t
is too high, the line pressure will decrease during
idling, with the result that a correct adjustment c annot
be made.
