DESCRIPTION
The motor generator control ECU, which is built into the inverter with converter assembly, detects pre-boosting high voltage (VL) using the voltage sensor in the boost converter to control boosting. The motor generator control ECU also monitors the boost converter voltage sensor signal line and detects malfunctions.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
---|---|---|---|---|---|
P0E3116 | DC/DC Converter Voltage Sensor "A"(VL) Circuit Voltage Below Threshold | Boost converter voltage (VL) signal is stuck (Low) (1 trip detection logic) | Inverter with converter assembly | Comes on | Master Warning Light: Comes on |
P0E3117 | DC/DC Converter Voltage Sensor "A"(VL) Circuit Voltage Above Threshold | Boost converter voltage (VL) signal is stuck (High) (1 trip detection logic) | Inverter with converter assembly | Comes on | Master Warning Light: Comes on |
P0E311F | DC/DC Converter Voltage Sensor "A"(VL) Circuit Intermittent | Boost converter voltage (VL) signal is stuck (Low) or (High) detected when DTC P0C7917, P0D3319, P0E5717, P1C5D19 or P1C5F19 is stored. (1 trip detection logic) | Inverter with converter assembly | Does not come on | Master Warning Light: Does not come on |

P0E3116, P0E3117 or P0E311F may be stored due to a malfunction which also causes the DTCs in the preceding table to be stored. In this case, first troubleshoot the output DTCs in the preceding table. Then, perform a test to attempt to reproduce the problems, and check that no DTCs are output.
(e) Turn the power switch off.
