7454 SPN Fault Code

Name:

Hybrid System High Voltage Exposure Indicator

Description:

This signal indicates the condition and state of the the hybrid system or electric vehicle system high voltage exposure detection system (e.g. High Voltage Interlock Loop [HVIL]). The high voltage exposure detection system is used to detect situations on a vehicle where personnel or property may be exposed to high voltage.The Error state indicates that the detection system may not be operational, and exposure status cannot be determined. For example, the detection system may not be operational due to electrical issues detected within its circuitry (e.g. short to battery, short to ground) or it has been intentionally disabled. 00b = System is operational and intact; no potential high voltage exposure has been detected 01b = System is operational and has detected a compromise; potential high voltage exposure exists 10b = Error 11b = Not Available

7454 spn fault code name is Hybrid System High Voltage Exposure Indicator. If you don't take the time to look into 7454 spn fault when it arises, it can add up quickly. One small issue like 7454 can cause a larger component to become damaged without taking the time to investigate. If you suspect your truck is suffering from one of these issues, look into replacing those small components to save money down the road.

Note: The name and description of 7454 code represents text descriptions for faults supported by another coding system and does not necessarily comply with SAE J1939. For a specific engine manufacturer's explanation for codes, please consult the engine's technical manual. See also other spn codes.
