DTC P1DE0-450: U Phase Output Diode Circuit; DTC P1DE1-450: V Phase Output Diode Circuit; DTC P1DE2-450: W Phase Output Diode Circuit; DTC P1DE3-450: X Phase Output Diode Circuit [06/2015 - ]: Description
The FC boost control ECU is located inside the FC converter assembly. It monitors the electric current of the circuits using the reactor current sensor inside the FC converter assembly and detects a short in the diode circuits.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | Warning Indicate |
|---|---|---|---|---|
| P1DE0-450 | U Phase Output Diode Circuit | A short in the U phase output diode circuit is detected. (The U phase reactor current output from the negative terminal is estimated to be caused by a reverse charging of the FC stack.) (1 trip detection logic) |
FC converter assembly | Master Warning Light: Comes on |
| P1DE1-450 | V Phase Output Diode Circuit | A short in the V phase output diode circuit is detected. (The V phase reactor current output from the negative terminal is estimated to be caused by a reverse charging of the FC stack.) (1 trip detection logic) |
FC converter assembly | Master Warning Light: Comes on |
| P1DE2-450 | W Phase Output Diode Circuit | A short in the W phase output diode circuit is detected. (The W phase reactor current output from the negative terminal is estimated to be caused by a reverse charging of the FC stack.) (1 trip detection logic) |
FC converter assembly | Master Warning Light: Comes on |
| P1DE3-450 | X Phase Output Diode Circuit | A short in the X phase output diode circuit is detected. (The X phase reactor current output from the negative terminal is estimated to be caused by a reverse charging of the FC stack.) (1 trip detection logic) |
FC converter assembly | Master Warning Light: Comes on |
