CP_a189 — Resistive Presence Rationality
Full alert identifier: CP_a189_resistivePresenceRationality
Alert description
The Charge Port (CP) Electronic Control Unit (ECU) is reading irrational values from resistive divider located in the CP door, which may prevent the CP door from opening when pressed.
Potential impact
The CP may not be able to determine the state of the manual door.
Set condition
The values from the resistive divider in the CP door are outside of the expected range.
Clear condition
The values from the resistive divider in the CP door are within the expected range.
