P0DE6 Hybrid/EV Battery Pack Cell Voltage Low

P0DE6 means the battery controller has measured at least one cell of the high-voltage pack below its lower voltage limit. It concerns a real reading, not the sensing lines (P0B3D and similar), and it looks at the weakest cell rather than the charge of the whole pack (P0A7D). Ford pairs it with P0A7D on 2020 Escape and Explorer hybrids drained by long standing or failed starts; a rescue charge needs the lowest cell above 1.45 V and a cell spread under 2.5 V (SSM 49163, later 51460, 52230 and 52773 for 2023-24 models). Stellantis fixes P0DE6 with BPCM software on the 2024-25 Dodge Charger EV and Jeep Wagoneer S, and on the 2026 Cherokee hybrid lengthened its maturing time for cold cranks. A no-start or reduced power is typical.

Likely causes

Pack deeply discharged after long standing or repeated failed starts
Battery controller software judging too strictly (e.g. cold cranking)
Single weak cell with high self-discharge or lost capacity
Cell balancing circuit draining one cell

Symptoms

  • Vehicle will not start or switch to ready
  • Reduced power, no electric driving
  • Malfunction indicator lamp on
