BMS_w126_HW_BMS_Blind_Mate

The Complex Programmable Logic Device (CPLD) of the High Voltage (HV) Battery Management System (BMS) detects a blind mate fault bit.

Live incidence rate

<0.01% (Extremely rare)

Vehicle messages

None displayed

Impact

The HV connector on the battery pack is not connected to the HVIL loop. HVIL behavior may be affected.

Description

The Complex Programmable Logic Device (CPLD) of the High Voltage (HV) Battery Management System (BMS) detects a blind mate fault bit.

Cause

The CPLD of the HV BMS detects a blind mate fault bit. The HVIL is on and HVIL voltage is greater than the blind mate alert threshold. The CPLD and the BMS concurrently detect the HVIL loop through the HV connector on the battery may not be connected.

Clear condition

The alert clears when the blind mate is cleared in the CPLD.
