- CHECK Shut Down Signal Circuit
.
Check Shut Down Signal Circuit. Ref. to P-HEV HYBRID POWERTRAIN CONTROL (DIAGNOSTICS)>DIAGNOSTICS WITH PHENOMENON>INSPECTION>SHUT DOWN SIGNAL CIRCUIT .
Is the check result of Shut Down Signal Circuit OK?
Yes : Replace Inverter with converter assembly. Ref. to HYBRID ELECTRIC VEHICLE>INVERTER AND CONVERTER ASSEMBLY .
No : Repair Shut Down Signal Circuit.
