Description

Error signal received from laser sensor

Detection condition

• Instrument cluster detects the following conditions:

• The smart city brake support operated normally in the past.

• Malfunction of laser sensor or smart city brake support related system (laser sensor, DSC HU/CM, PCM)

• Laser sensor control is temporarily inhibited.

Fail-safe function

• Detection condition: The smart city brake support operated normally in the past.

• Not applicable

• Detection condition: Malfunction in laser sensor or smart city brake support related system (laser sensor, DSC HU/CM, PCM)

• Inhibits the smart city brake support control.

• Warning message related to the smart city brake support is displayed on the LCD (Instrument cluster (type A)).

• Detection condition: Laser sensor control is temporarily inhibited.

• Temporarily inhibits the smart city brake support control.

Possible cause

NOTE:

• Instrument cluster stores DTC U0433:00 as a record that the smart city brake support operated normally.

• System related to the smart city brake support stores DTCs.

• The laser sensor cannot temporarily function due to dirt on the windshield.

• Laser sensor malfunction

• Instrument cluster malfunction
