HINT:

○: Stored.

x: When one side of branch wire is open, storage may occur.

*1: Only stored when communication recovery has occurred. During communication stop, cannot be stored.

*2: Stored when vehicle speed is 15 km/h (9 mph) or more.

*3: This DTC is not stored when only the spd signal is lost. When any of DTCs C2121 to C2125 is stored and the spd signal is lost, this DTC is stored.

*4: Stored when vehicle speed is 30 km/h (18 mph) or more.

*5: The ECM receives diagnosis data from the distance control ECU and stores a DTC.

*6: The seat belt control ECU receives diagnosis data from the distance control ECU and stores a DTC.
