Pressure Testing
. While testing, be careful of the rot8ling front wheels.
. M8k6 suro lifts, iacks, and satety stands are placed properly lsee section 11.
CAUTION:
. Before testing, be sur. the transmb3ion fluid is fillod to the propor lcvel.. Warm up the engin€ to nolmal operating tsmperature bofore testing. While t€sting, be 3ure not to allow dust and other loreign particles to onler into the transmi$ion.
1. Raise the front of the vehicle, and support it with safety stands (see section 1).
2. Set the parking brake. and block both rear wheels securely.
3. Allow the front wheels to rotate freely.
4. Warm up the engine (the radiator fan comes on), then stop arid connect a tachometer.
5. Connect the special tool to each inspection hole.
TOROUE: 18 N.m (1.8 kgt'm, 13 tbtfr)
GAUTION:
. Connect the oil pressuro gauge !!€curoly, bs sur6 not to allow dust and other foroign particlG3 to ontar the inspsc-tion hole.
. Whon troubleshooting by tho E indicltor light indic.t6 a problam. you mu3t u3e an oil p.essure gluge that moa,sures 4,9(X) kPa (a.90 MPa,50.0 kS cr*,771psi) or more when molsuring driv. pulley pressure and driven pullcypre33ure.
NOTE:
. D.ive pulley pressure may be above 3,430 kPa (3.i8 MPa,35.0 kgf/cmr, 498 psi) wh€n there is a transmission prob-
lem that causes the TCM or PCM to go into the fail-safe mode,. Use a commercially available oil pressure gauge that measures 4,900 kPa {4.90 MPa, 5O.O kgf/cmr, 711 psi) ormore, and the Ay'T Oil Pressure Hose, 2210 mm (07MAJ - PY4011A).

Adjustment
!@ Make sure lifts, jacks and safety stands are
placed properly (see section 1).
l. Remove the front console (see section 20).
2. Shift to I posirion, then remove the lock pin from
the adjuster.

3. Check that the hole in the adiuster is perfectly aligned
with the hole in the shift cable. There are two holes in
the adjuster. They are positioned 90" apart to allow
cable adjustment in 1/4 turn increments.
lf the hole is not perfectly aligned, loosen the lock-
nut on the adjuster and adjust as required.
Tighten rhe locknut to 7 N.m (0.7 kgim,5 lbf'ft).
Install the lock pin on the adjuster' lf you feel the
lock pin binding as you reinstall it. the cable is still
out of adjustment and must be readjusted
Make sure the lock pin is seated in the adiuster
securery.
lMove the shift lever to each position, and verify that
the shift position indicator follows the automatlc
transaxle gear position switch.
Start the engine, and check the shift lever in all
positions. lf any gear does not work properly, refer
to troubleshooting (see page 14-294 and 14-295).
Insert the ignition key into the key cylinder on the
Aff gear position indicator panel, and verify that the
shift lock lever is released.

Troubleshooting
General Troubleshooting
Check the following before you begin:. Has the suspension been modified in a way that would affect steering?. Are tire sizes, tire variety and air pressure correct?. lsthe steering wheel original equipment or equivalent?. lsthe powersteering pump belt properlyadiusted?
. ls steeringfluid reservoirfilledto proper level?. ls the engine idle speed correct and steady?
Hard Steering (Check the powor assist. se€ page 17-3o. lfthe torce is over 29 N (3.0 kgf, 6.6lbo, Procede with this troubleshootinq.)
Abnormallluid pressure

Check th€ flow control vslve (see page 17-42).. Chock the valvo lor smooth movement in the hous-ing.. Check the reliefvalve for leaks.
Check the pump fluid pressure
{see page 17-34).Measure pump relief pressurewhile idling with the pressure con-trol valve Iully closed.It should be 6,400 - 7,400 kPa (65 -
