P0CA6Hybrid/EV Battery Charging Current High

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
  • Needs a drive cycle to confirm a fix
How the car detects it
P0CA6 flags a current into the traction battery that exceeds what the control system expects. Mitsubishi's Outlander PHEV (2018 and 2022) stores it in the PHEV-ECU when, in charging mode, the measured battery current stays above the calculated charger output request for 5 s; suspects are the BMU, the onboard charger/DC-DC converter and the PHEV-ECU, and the repair is confirmed with drive cycle pattern 7. Stellantis sees the code in the battery pack control module (BPCM): a 2023 STAR case for the Wrangler 4xe points to BPCM software, and bulletin 08-025-25 for the 2025 Dodge Charger EV brings charging-related changes against false P0CA6 entries, there combined with P167B and no Drive Ready. P0CA7 is the discharging counterpart.

Likely causes
  • LikelyBattery control module software (Stellantis S2308000117, 08-025-25)
  • PossibleOnboard charger or DC-DC converter delivering more current than requested
  • PossiblePack current sensor or battery management unit reading wrongly
  • RareFault in the hybrid/PHEV control unit
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
