PARK ASSIST / MONITORING BLIND SPOT MONITOR SENSOR ADJUSTMENT

PROCEDURE

Hide Display 1. BSM ECU DATA SAVE

NOTICE:: ·

Confirm that communication malfunction with other parts is not detected before changing blind spot monitor sensor.

·

When the ECU data cannot be saved due to an ECU malfunction or a communication malfunction, perform the blind spot monitor beam axis confirmation.

·

In the following situations, perform blind spot monitor beam axis confirmation after the blind spot monitor sensor has been replaced with a new one.

-

When a minor collision is suspected.

-

For a vehicle that has undergone sheet metal repairs.

-

For a vehicle in which the system frequently operates inappropriately or fails to operate.

-

When a DTC for rear side radar sensor (module "B") axis misalignment (horizontal) or rear side radar sensor (module "A") axis misalignment (horizontal) has been stored.

-

When RoB code for rear side radar sensor (module "B") beam axis not adjusted or rear side radar sensor (module "A") beam axis not adjusted has been stored.

-

When RoB code for rear side radar sensor (module "B") Blockage or rear side radar sensor (module "A") Blockage has been stored.

-

When RoB code for rear side radar sensor (module "B") Blockage Level 2 or rear side radar sensor (module "A") Blockage Level 2 has been stored.

HINT:: By performing BSM "A" ECU data save or BSM "B" ECU data save, it becomes possible to save the beam axis adjustment value to the GTS.

Connect the GTS to the DLC3.

Turn the ignition switch to ON.

Enter the following menus: Body Electrical / Blind Spot Monitor "A" or Blind Spot Monitor "B" / Utility.

HINT:: The "B" is on the LH side and the "A" is on the RH side.

Hide Display 2. BSM ECU DATA WRITE

NOTICE:: ·

The value saved from the old blind spot monitor sensor RH before replacement should be written to the new blind spot monitor sensor RH.

·

The value saved from the old blind spot monitor sensor LH before replacement should be written to the new blind spot monitor sensor LH.

·

In the following situations, to prevent incorrect or unnecessary operation of the blind spot monitor sensor, do not perform the procedure to write data to the BSM ECU.

-

When the BSM data was copied from a different vehicle than the one to which BSM data will be written.

-

When the BSM ECU data saved from the old blind spot monitor sensor LH before replacement will be written to a new blind spot monitor sensor RH.

-

When the BSM ECU data saved from the old blind spot monitor sensor RH before replacement will be written to a new blind spot monitor sensor LH.

HINT:: By performing BSM "A" ECU data write or BSM "B" ECU data write, the beam axis adjustment value from the old blind spot monitor sensor before replacement can be written to the new blind spot monitor sensor.

Connect the GTS to the DLC3.

Turn the ignition switch to ON.

Enter the following menus: Body Electrical / Blind Spot Monitor "A" or Blind Spot Monitor "B" / Utility.

Hide Display 3.PERFORM BLIND SPOT MONITOR BEAM AXIS CONFIRMATION

HINT:: The blind spot monitor beam axis confirmation is performed to confirm whether the sensor beam axis is correct, and to adjust the beam axis by using a reflector.

When performing the blind spot monitor beam axis confirmation, move the vehicle to a place where the space shown in the illustration can be secured.
