NOTICE:

When checking for DTCs, make sure that the blind spot monitor system is turned on.

CHECK DTC

(a) Turn the ignition switch off.

(b) Turn the ignition switch to ON.

Result	Proceed to
Blind Spot Monitor Master DTCs including DTC U0232 are output.	A
Blind Spot Monitor Master DTCs other than DTC U0232 are output.	B
No DTCs are output	C

HINT:

If CAN communication system DTCs are stored, they may also be stored for other systems.
If the CAN communication system has been inspected and repaired, the DTCs will not be output when rechecking for DTCs.
If these DTCs are output frequently, duplicate the conditions that cause the problem symptoms and perform the inspection again, even if the DTCs were not output when rechecking for DTCs.
