HINT
* Use these procedures to troubleshoot the dynamic radar cruise control system.
* *: Use the Techstream.

1. VEHICLE BROUGHT TO WORKSHOP

NEXT -- Continue to next step.

2. INSPECT BATTERY VOLTAGE

Standard voltage:

11 to 14 V

If the voltage is below 11 V, replace or recharge the battery before proceeding.

NEXT -- Continue to next step.

3. CHECK FOR DTC (ELECTRIC POWER CONTROL SYSTEM)*

(a) Using the Techstream, check if the electric power control system is functioning normally.

Result

NEXT -- Continue to next step.

9. ADJUST, REPAIR OR REPLACE

NOTICE:
* If the driving support ECU has been replaced, turn the engine switch off -> on (IG) for 10 seconds -> off to perform the initialization.
* When the front millimeter wave radar sensor is replaced with a new one, adjustment of the radar sensor beam axis must be performed Installation.

NEXT -- Continue to next step.

10. CONFIRMATION TEST
