BOOT
Check boot for cracks. Replace if any damage is found.
OUTER SOCKET AND INNER SOCKET
• Ball joint swinging torque
- Hook a spring balance to the ball stud and inner socket measuring point (*) and pull the spring balance. Make sure that the spring bal-
ance reads the specified value when ball stud and inner socket
start to move. Replace outer socket and inner socket if they are
outside the specification.
• Ball joint rotating torque
- Make sure that the reading is within the following specified range
using Tool. Replace outer socket if the reading is outside the spec-
ification.
• Ball joint axial end play
- Apply an axial load of 490 N (50 kg, 111 lb.) to ball stud. Measuring
the amount of stud movement using a dial gauge, make sure that
the value is within specificati on. Replace outer socket and inner
socket if the measured value is outside specification. Tool number : — (J-44372)

Diagnosis ProcedureINFOID:0000000009460378
1.PERFORM SELF-DIAGNOSIS
With CONSULT
Perform “EPS” self-diagnosis.
Is a malfunctioning system displayed?
YES >> Check malfunctioning system. Refer to STC-13, "DTC Index".
NO >> GO TO 2.
2.CHECK THE POWER STEERING CONTROL MODULE SIGNAL (1)
With CONSULT
1. Start the engine. CAUTION:
Never drive the vehicle.
2. Turn the steering wheel until it stops.
3. Select “MTR ASSIST” in “DATA MONITOR” of “EPS”.
Is the display value
“100%”?
YES >> GO TO 4.
NO >> GO TO 3.
3.CHECK THE POWER STEERING CONTROL MODULE SIGNAL (2)
With CONSULT
1. Select “C/U TEMP” and “C/U TEMP A” in “DATA MONITOR” of “EPS”.
2. Stop the system until the DATA MONITOR display value drops to “90 °C (194 °F)” or less.
3. Check whether symptom continues.
Did symptom continue?
YES >> GO TO 4.
NO >> This occurs because the protection function lowers the assist force. It is not a system malfunction.
Inspection End.
4.CHECK THE POWER STEERING CONTROL MODULE SIGNAL (3)
With CONSULT
1. Turn the steering wheel to the straight -ahead position. (There is no steering force.)
2. Select “BATTERY VOLT” in “DATA MONITOR” of “EPS”.
Is the display value
“10.5 V” or more?
YES >> GO TO 5.
NO >> Check the battery power system. Refer to STC-23, "Diagnosis Procedure"
.
5.CHECK THE POWER STEERING CONTROL MODULE SIGNAL (4)
With CONSULT
Select in “ESTM VHCL SPD” in “DATA MONITOR” of “EPS”.
*: This may not agree with the speedometer indication immediately after the ignition switch is turned ON. This
is not a malfunction.
Is the check result normal?
YES >> GO TO 6.
Monitor item Test condition Display value
