NO.2 TIGHT CORNER BRAKING

Tight corner braking

[TROUBLESHOOTING HINTS]

• Because the coupling component locks up easily (similar to direct 4WD), rotational difference between the front and rear wheels cannot be absorbed and brake-like phenomenon occurs.

• Due to the coupling component construction, slight tight corner braking effect occurs during tight cornering on a paved road. (4WD system is okay. Compare with another same model vehicle to determine malfunction.)

• Coupling component malfunction

• 4WD solenoid malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY DSC, PCM, TCM, AND 4WD SYSTEM DTCS
• Verify DSC, PCM, TCM, and 4WD system DTCs using WDS or equivalent.
• Are there any DTCs present?
Yes
Go to applicable DTC inspection.
No
Go to next step.
2
VERIFY TIRE AIR PRESSURE
• Inspect tire air pressure.
• Is it within specification?
Yes
Go to next step.
No
Adjust tire air pressure, then go to next step.
3
INSPECT ABS WHEEL-SPEED SENSOR
• Inspect ABS wheel-speed sensor.
• Is it okay?
Yes
Go to next step.
No
Repair or replace malfunctioning part.
4
COMPARE WITH SAME MODEL VEHICLE
• Perform simulation driving with another same model vehicle.
• Does malfunction recur on the same model vehicle?
Yes
4WD system is okay.
No
Go to next step.
5
PERFORM SIMULATION DRIVING WITH 4WD SOLENOID CONNECTOR DISCONNECTED
• Turn ignition key OFF.
• Disconnect 4WD solenoid connector.
• Perform simulation driving. (Clear DTC after simulation driving.)
• Does malfunction recur?
Yes
Replace coupling component. (See COUPLING COMPONENT REMOVAL/INSTALLATION [L3].)
No
Go to next step.
6
INSPECT 4WD SOLENOID
• Inspect 4WD solenoid.
• Is it okay?
Yes
Inspect harness between 4WD solenoid and 4WD CM, then go to next step.
No
Replace coupling component. (See COUPLING COMPONENT REMOVAL/INSTALLATION [L3].)
