Driving Support DTC Troubleshooting Index

NOTE: 

• The DTC troubleshooting index shows DTCs that are stored in the integrated driver support system. Each function of the integrated driver support system operates differently according to which DTC is stored. The functions of the integrated driver support system that operate in condition when these DTCs are stored can be confirmed with the table below:

  : Indicator ON, and operation stop

  o: Operation stop

  Δ: Indicator blink, and operation stop

• For the millimeter wave radar, different indicators may be lit for the same DTCs depending on which functions are in operation when the DTCs are stored. Make sure to check following DTCs with asterisks before troubleshoot them.

NOTE:  For details on the functions of indicators, and operation stop, refer to "How to Troubleshooting Information."

• How to Troubleshoot the Adaptive Cruise Control (ACC) 
• How to Troubleshoot the Collision Mitigation Braking System (CMBS)
• How to Troubleshoot the Lane Keeping Assist System (LKAS)
• How to Troubleshoot the Road Departure Mitigation
• Brake System (How to Troubleshoot the VSA System)
• How to Troubleshoot the Auto High-Beam
