No.5 TIGHT-CORNER BRAKING PHENOMENON OCCURS
id030300801100
Possible Cause
• The 4WD lock system is designed to improve driveability on snow covered roads and free a stuck vehicle. Abnormal noise or vibration may occur while turning on a dry surface with the 4WD lock on.
• 4WD lock solenoid malfunction (sticking in 4WD lock)
• The difference in front and rear wheel rotation cannot be absorbed due to a high locking rate of the RBC unit (close to that of 4WD lock) and this causes a braking phenomenon.
• Tight-corner braking phenomenon occurs while turning sharply on a dry surface because of the RBC unit construction. (Verify that the 4WD system is normal by comparing with another vehicle.)
• RBC unit malfunction
Diagnostic Procedure
|
STEP
|
INSPECTION
|
ACTION
|
|
1
|
INSPECT TIRE PRESSURE
• Inspect the tire pressure.
• Is the tire pressure normal?
|
Yes
|
Go to the next step.
|
|
No
|
Adjust the tire pressure to the specification and drive the vehicle. If the malfunction is verified, go to the next step.
|
|
2
|
COMPARE WITH ANOTHER VEHICLE
• Perform the driving test with another vehicle.
• Does the malfunction occur in another vehicle?
|
Yes
|
The 4WD system is normal.
|
|
No
|
Go to the next step.
|
|
3
|
INSPECT 4WD LOCK SOLENOID
• Inspect the 4WD lock solenoid.
• Is the 4WD lock solenoid normal?
|
Yes
|
Perform the diagnostic procedure "No.2 MODE CHANGE BETWEEN AUTO AND 4 X 4 ON IS NOT PERFORMED NORMALLY".
|
|
No
|
Replace the RBC unit.
