NO.2 TIGHT CORNER BRAKING

id030300800500

2 | 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. (See 4WD SOLENOID INSPECTION [L3]) (See 4WD SOLENOID INSPECTION [L3 Turbo]) • 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].) (See COUPLING COMPONENT REMOVAL/INSTALLATION [L3 Turbo].)
