P0A0D / INF351
P0A0D-350, P0A0D-351Description
When the hybrid vehicle control ECU detects that a safety device is operated, it will prohibit the hybrid system operation or shut off the system main relay. There are three safety devices in three different locations. The first safety device is located at the service plug grip. The second one is located at the air conditioner fuse maintenance compressor fuse cover of the inverter with converter assembly.
The third one is located at the air conditioning harness assembly that is connected to the inverter with converter assembly. If the service plug grip, compressor fuse cover, or air conditioning harness assembly is removed, the interlock signal line will be open. If the vehicle is being driven, this condition will be determined to be an open malfunction and the system main relay will not be shut off. If the safety devices are installed correctly, the system returns to normal when the ignition switch is turned ON.
