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.
* : Vehicle identification number (VIN): Except European (U.K.) specs. (JM0 KE****** 200001—, JM6 KE****** 200001—, JM8 KE****** 200001, JMZ KE****** 200001, KE10** 200001—), European (U.K.) specs. (JMZ KE****** 158745—)
Fail-safe
•  Detection condition: The smart city brake support operated normally in the past.
―  Function not equipped.
•  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 TFT LCD display.
•  Detection condition: Laser sensor control is temporarily inhibited.

* : Vehicle identification number (VIN): Except European (U.K.) specs. (JM0 KE****** 200001—, JM6 KE****** 200001—, JM8 KE****** 200001, JMZ KE****** 200001, KE10** 200001—), European (U.K.) specs. (JMZ KE****** 158745—)
Possible cause
Note
•  The 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

Diagnostic Procedure

Step

Inspection

Action
1
VERIFY ALL SYSTEM DTCs
•  Switch the ignition to off.
•  Switch the ignition ON (engine off or on) and wait for 10 s or more.
•  Perform a CMDTC self-test using the M-MDS.
•  Are any DTCs other than DTC U0433:00 displayed?
Yes
Repair the malfunctioning part according to the applicable system DTC troubleshooting.
(See DTC TABLE [INSTRUMENT CLUSTER].)
No
Go to the next step.
2
VERIFY DTCs AGAIN
•  Clear DTC for the instrument cluster using the M-MDS.
•  Switch the ignition ON (engine off or on) and wait for 10 s or more.
•  Perform a CMDTC self-test using the M-MDS.
•  Is DTC U0433:00 displayed?
Yes
Go to the next step.
No
Go to Step 6.
3
VERIFY TFT LCD DISPLAY
•  Verify the TFT LCD display.
•  Is “SCBS Clear windshield completely” or “SCBS Not Available” displayed in the TFT LCD display?
Yes
Clean the windshield, then go to the next step.
No
Go to Step 5.
4
PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTION CAUSE IS LASER SENSOR

•  Perform a CMDTC self-test using the M-MDS.
•  Is DTC U0433:00 displayed?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the instrument cluster, then go to the next step.
No
Go to the next step.
6
VERIFY IF OTHER DTCs DISPLAYED
