Noise Hissing Noise in Steering Gear
There is some noise with all power steering systems. One of the most common is a hissing
sound when the steering wheel is turned and the car is not moving. This noise will be most
evident when turning the wheel while the brakes are being applied. There is no relationship
between this noise and steering performance. Do not replace the valve unless the "hissing"
noise becomes extreme. A replaced valve will also make a slight noise, and is not always a
solution for the condition.

Symptom Probable cause Remedy
There is no change made in rack
stroke even though turning the VRS
switch ON or OFF. a.
VRS operating unit
b. VRS control module
c. VRS switch a.
Inspect the VRS operating unit.
b. Check Input/ output signal of the
VRS control module.

turning the VRS switch ON. VRS switch a.
Inspect connection of the VRS
switch.
b. Check the LED for damage.
Inspection of the rack stroke
1.Is the rack stoke (the maximum steering angle) changed when pressing the VRS switch ?
▶ The VRS system is in normal condition.
▶ Go to step 2.
2. Measure the resistance of the VRS operating unit.
(1) Disconnect the VRS operating unit connector.
(2) Measure the resistance between the terminal No.1 and No.2.
Repeat the terminal No.3 and No.4.
Is the measured resistance within standard value ?
4 ~ 20 Ω → Normal condition (standard value)
1 Ω or below → Short
100 Ω or above → Open circuit
▶ Go to step 3.
▶ Repair or replace the power steering gear box.
3. Measure the output voltage of the VRS control module.
(1) Disconnect the VRS control module connector.
(2) Connect 9 ~ 15 V power between the terminal No.3 and No.4.
(3) Measure the output voltage (to DC motor) between the terminal No.5 ~ 8.
Is the voltage measured within standard value ?
Supplied power Measured output voltage

Supplied powerStandard valueVRS CM failure
9 V 8 V or above Below 8 V
12 V 11 V or above Below 11 V
15 V 14 V or above Below 14 V
▶ Inspect connection of connectors and harness for the VRS system.
▶ Replace the VRS control module.
1. Is the LED on the VRS switch illuminated when turning the VRS switch ON?
▶ The VRS switch has normal condition.
▶ Go to step 2.
2. Inspect the VRS switch connector.
(1) Disconnect the VRS switch connector.
(2) Connect 12 V power between terminal No. 1 (+) and No.3 ( - ).
Check if the LED is turned ON or OFF by pressing the VRS switch.
Is the LED turned ON or OFF when pressing the VRS switch ?
▶ The VRS switch is in normal condition.
▶ Repair or replace the VRS switch.

REFRIGERANT SYSTEM SERVICE BASICS
REFRIGERANT RECOVERY
Use only service equipment that is U.L - listed and is certified to meet the requirements of SAE J2210 to remove HFC-
134a(R- 134a) from the air conditioning system.
a. Air conditioning refrigerant or lubricant vapor can irritate your eyes, nose, or throat.
b. Be careful when connecting service equipment.
c. Do not breathe refrigerant or vapor.
If accidental system discharge occurs, ventilate work area before resuming service.
Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers. 1. Connect an R- 134a refrigerant
Recovery/Recycling/Charging System (A) to the high- pressure service port (B) and the low- pressure service port
(C) as shown, following the equipment manufacturer's instructions.
2.Measure the amount of refrigerant oil removed from the A/C system after the recovery process is completed. Be
sure to install the same amount of new refrigerant oil back into the A/C system before charging.
SYSTEM EVACUATION
Use only service equipment that is U.L - listed and is certified to meet the requirements of SAE J2210 to remove HFC-
134a(R- 134a) from the air conditioning system.
a.Air conditioning refrigerant or lubricant vapor can irritate your eyes, nose, or throat.
