Inspection and Adjustment
Pump Pressure Check
Check the fluid Dressure as follows to determine
whether the trouble is in the pump or gearbox.
NOTE; First check the power steering fluid level and
pump belt tension.
CAUTION: Disconnect the pump outlet hose (high-pres-
sure line) with care so as not to spill the power steering
fluid on the frame and other parts,
1. Disconnect the pump outlet hose (high-pressure)
from the pump outlet fitting, then install the P/S
joint adapter (pump) on the pump outlet.

PUMPFITTING
Connect the P/S joint adapter (hose) to the power
steering pressure gauge, then connect the pump
outlet hose (high-pressure)to the adapter.
Install the power steering pressure gauge to the P/S
joint adapter (pump).
Open the shut-off valve fully.
Open the pressure control valve fulli.
1.
Start the engine and let it idle.
Turn the steering wheel from lock-to-lock several
times to warm the fluid to operating temperature.
Measure steady-state fluid pressure while idling. lf
the pump is in good condition, the gauge should
read less than 1500 kPa (15 kgflcm',213 psi).
lf it reads high, check the outlet hose or valve body
unit (see General Troubleshooting 17-101.
Close the pressure control valve, then close the
shut-off valve gradually until the pressure gauge
needle is stable, Read the pressure.
lmmediately open the pressure control valve fully.
CAUTION: Do not keep the pressure control valve
closed more then 5 seconds or the pump could be
damaged by over-heating.
lf the pump is in good condition, the gauge should
read at least 6,400 - 7,400 kPa (65 - 75 kgflcm',924- 1,067 psi). A low.eading means pump output is
too low for full assist. Repair or replace the pump.

Troubleshooting Precautions
Kickback
L The motor operates when the ABS is functioning, and the fluid in the reservoir is forced out to the master cylinder,
causing kickback at the brake pedal.
Pump Motol
1. The pump motor operates when the ABS is functioning.
2. The ABS control unit checks the pump motor operation during initial diagnosis and when the vehicle is started. You
mav hear the motor operate at this time, but it is normal
Brake Fluid Replacement/Air Bleeding'1. Brake fluid replacement and air bleeding procedures are the same as vehicles without ABS. To ease bleeding, start
with the front wheels.
Troubleshooting
1. The troubleshooting flowcharts procedures assume that the cause of the problem is still present and the ABS indica-
tor is still on. Following the flowchart when the ABS indicator does not come on can result in incorrect diagnosis.
2. Ouestion the customer about the conditions when the problem occurred, and try to reproduce the same conditions
for troubleshooting.
Find out when the ABS indjcator came on. such as during initial diagnosis. during ABS control, after ABS control,
when vehicle speed was at a certain speed, etc.
3, When the ABS indicator does not come on during the test-drive, but troubleshooting is performed based on the DTC,
check for loose connectors, poor contact at the terminals, etc. before you start troubleshooting'
4. After troubleshooting, erase the DTC and test-drive the vehicle. Be sure the ABS indicator does not come on.
5. The connector illustrations show the female terminals with a single outline and the male terminals with a double outline.

SYMPTOMREMEDY
Hot air tlow is low.Blower motor runs, but one or more
speeds are inoperative.
Follow the flowchart (see page 21-9).
Blower runs propetly.Check for the following:. Clogged heater duct
. Clogged heater outlet
. Incorrect door Position
No hot air tlowBlower motor does not run at all.Follow the flowchart {see page 21-11}
Blower motor runs.Check for the following:
. clogged heater duct
. Clogged blower outlet. Clogged heatet valve
. Faultv air mix door
. Heater valve cable adjustment lsee page 21-27].
. Air mix control cable adiustment {see page 21-27)
. Faulty thermostat (see section 10)
. Clogged evsporator (with air conditioning)
. Frozen evaDorator (with air conditioning)
Mode control motor does not run, or one or more mooes are
inoDeratave.
Follow the flowchart (see page 21-14).
Recirculation control door does not change between FRESH
and RECIRCULATE.
Follow the flowchart {see page 21-17).

When the refrigerant pressure is below 200 kPa (2.0
