HOW TO PROCEED WITH TROUBLESHOOTING
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





B -- Go to ELECTRIC POWER CONTROL SYSTEM
A -- Continue to next step.

NEXT -- Continue to next step.

9. ADJUST, REPAIR OR REPLACE
NOTICE:
- If the driving support ECU has been replaced, turn the power 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
NEXT -- END
