Diagnostic Method
- Stuck
Judge as NG when the following conditions are repeated 10 times or more.
JUDGMENT VALUE SPECIFICATIONMalfunction Criteria Threshold Value Difference between maximum value and minimum value in output voltage < 0.07 V Time needed for diagnosis: Less than 1 second
Malfunction indicator light illumination: Does not illuminate even when malfunction occurs.
- Characteristics malfunction (charge side)
Within 30000 ms from "enable condition not met" to "enable condition met", judge as NG when the time required for meeting the following conditions exceeds the predetermined time.
(When NG judgment is performed, NG status is retained during that driving cycle.)
JUDGMENT VALUE SPECIFICATIONMalfunction Criteria Threshold Value Output voltage 0 V ≤ Output voltage < 2.4 V and Battery voltage < 13.2 V Time needed for diagnosis: 26000 ms
Malfunction indicator light illumination: Does not illuminate even when malfunction occurs.
- Characteristics malfunction (discharge side)
Within 30000 ms from "enable condition not met" to "enable condition met", judge as NG when the time required for meeting the following conditions exceeds the predetermined time.
(Within 30000 ms from "enable condition not met" to "enable condition met", the target duty ≥ 60% has not been experienced.)
JUDGMENT VALUE SPECIFICATIONMalfunction Criteria Threshold Value Output voltage 2.6 V ≤ Output voltage < 5 V and Battery voltage ≥ 13.7 V Time needed for diagnosis: 26000 ms
Malfunction indicator light illumination: Does not illuminate even when malfunction occurs.
