CCS-H07Cross-brand / Protocol · Cables & connectorsFree samplePP resistor out of range
PP resistor out of range (CCS-H07) — CCS handshake field fault. Stay OEM-agnostic until the protocol stage pins a hardware path; capture SECC/OCPP/vehicle evidence before opening the cabinet.
NACS-H02Cross-brand / Protocol · Cables & connectorsFree sampleNACS proximity detect intermittent
NACS proximity detect intermittent (NACS-H02) — NACS path field fault. Stay OEM-agnostic until the protocol stage pins a hardware path; capture SECC/OCPP/vehicle evidence before opening the cabinet.
NACS-H04Cross-brand / Protocol · Cables & connectorsFree sampleNACS PP open mid-session
NACS PP open mid-session (NACS-H04) — NACS path field fault. Stay OEM-agnostic until the protocol stage pins a hardware path; capture SECC/OCPP/vehicle evidence before opening the cabinet.
CP-E250-ISOChargePoint · Express 250 · DC Fast ChargersFree sampleIsolation fault after cable swap
Express 250 isolation fault before or during CableCheck after a cable swap, rain, or cooled-cable service — one gun or whole power cabinet. chargepoint field note: keep evidence scrubbed and prove the ranked cause before module RMA on CP-E250-ISO.
TRI-PK-CABLETritium · PK350 · Liquid coolingFree sampleLiquid-cooled cable leak detect
PK350 liquid-cooled cable leak detect — contain spill, reseal/replace path, bleed before return to service. Field techs should correlate HMI/Cloud timestamps with PK liquid-cooled path vs RTM air-cooled path changes isolation and thermal triage.
