>> GO TO 2.
2.CHECK LDP SYSTEM SETTING
1. Start the engine.
2. Check that the LDP system setting can be enabled/disabled on the navigation screen.
3. Turn OFF the ignition switch and wait for 30 seconds or more.
4. Check that the previous setting is saved when the engine starts again.
>> GO TO 3.
3.ACTION TEST FOR LDP
1. Enable the setting of the LDP system on the navigation screen.
2. Turn dynamic driver assistance switch ON (LDP ON indicator lamp is ON).
NOTE:
LDW system is OFF.
3. Check the LDP operation according to the following table.

LDP SYSTEM SETTINGS CANNOT BE TURNED ON/OFF ON THE NAVIGATION
SCREEN
LDP SYSTEM SETTINGS CANNOT BE TU RNED ON/OFF ON THE NAVI-
GATION SCREEN
DescriptionINFOID:0000000006223840
 LDP system setting is not selectable on the navigation screen. NOTE:
When the ignition switch is in ACC posit ion, LDP system settings cannot be changed.
- “Lane Departure Prevention” is not indicated on the navigation screen.
- The switching between ON and OFF cannot be per formed by operating the navigation system.
- The item of “Lane Departure Prevention” on the navigation screen is not active.
 After turning ON the ignition switch or starting the engine, LDP settings of the navigation system cannot be
selected for several tens of sec onds under the following conditions:
- After replacing AV control unit.
- After erasing connection histor y of the navigation system.
- After erasing self-diagnosis results.
 The LDP system setting differs from the one set at the previous driving. NOTE:
Turn OFF the ignition switch and wait for 5 seconds or more.
Diagnosis ProcedureINFOID:0000000006223841
1.CHECK LDP SYSTEM SETTING
1. Start the engine.
2. Check that the LDP system settings is selectable on the navigation screen.
Is the inspection result normal?
YES >> GO TO 3.
NO >> GO TO 2.
2.PERFORM THE SELF-DIAGNOSIS
1. Perform “All DTC Reading” with CONSULT-III.
2. Check if the DTC is detected in self-diagnosis results of “ICC/ADAS”, “MULTI AV” and “METER/M&A”.
Refer to the following.
- ICC/ADAS: DAS-310, "
DTC Index"
- MULTI AV: AV-57, "DTC Index"
- METER/M&A: MWI-43, "DTC Index"
Is any DTC detected?
YES >> Repair or replace malfunctioning parts.
NO >> INSPECTION END
3.CHECK DATA MONITOR OF ADAS CONTROL UNIT
Check that “LDP SELECT” operates normally in “D ATA MONITOR” of “ICC/ADAS” with CONSULT-III.
Is the inspection result normal?
YES >> Refer to AV-28, "On Board Diagnosis Function".
NO >> GO TO 4.
4.CHECK MULTIFUNCTION SWITCH
Operate the multifunction switch to check that the audio, navigation system, and air conditioner operate prop-
erly.
Is the inspection result normal?
YES >> Replace the ADAS control unit. Refer to DAS-63, "Removal and Installation".
NO >> Repair or replace malfunctioning parts.
