P0D35Hybrid/EV Battery System Current Unstable
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0D35 flags a battery system current that swings more than the operating state explains, for example rapid changes while the requested power is steady. No manufacturer publishes set conditions for this code. Possible sources are a loose high-voltage connection or a chattering contactor that briefly interrupts the flow, a consumer such as a compressor or heater that cycles abnormally, a current sensor with an intermittent signal, or a controller that oscillates in its regulation. Hitachi Astemo's patent on battery current detection compares several current values and treats a large spread between them as a fault, which illustrates how such instability can be caught. The sensor's own sporadic code is P0AC3; P0D35 concerns the current flow. CARB requires battery system performance monitoring. Power may be cut back.
- What you may notice

- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
