DTC SUMMARY
MALFUNCTION DESCRIPTION
These DTCs are stored when the generator temperature sensor output is abnormal. The cause of this malfunction may be one of the following:
Generator temperature sensor malfunctionHINT:
If any of these DTCs are stored, the generator temperature sensor is malfunctioning and the self-protection function may not operate. Therefore under certain high load driving condition, the temperature of the generator (MG1) becomes high. If the self-protection function does not operate, the generator (MG1) may malfunction and cause the vehicle to enter fail-safe mode.
