DTC P0A7A-9E: Generator Inverter Stuck On: Notes
- -
Detecting condition:
Generator inverter fail signal detection (circuit malfunction)
(1 trip detection logic)
Trouble symptom:
- Reduced output power
- A driving range is limited
- Engine always stopped
CAUTION:- Before performing diagnosis, refer to "CAUTION" in "General Description". Ref. to P-HEV DRIVE MOTOR (DIAGNOSTICS)>GENERAL DESCRIPTION>CAUTION .
- After the check is finished, always replace the Inverter with converter assembly. (Because it may be damaged by inverter overheat) Ref. to HYBRID ELECTRIC VEHICLE>INVERTER AND CONVERTER ASSEMBLY .
- CHECK DTC
.
