P0E68Battery Charger Control Circuit Range/Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- P0E68 is the plausibility code of the charger command line: no short or open is present, yet the charger does not react to the command in the expected way or in the expected time. Typical triggers are a charger that wakes too slowly, a voltage drop on the line that leaves the level ambiguous, or software in the two modules that disagrees. No manufacturer documents P0E68 publicly. A close analogue is Ford's P0E64 on its 2019 hybrids: once the charge wake-up line is high, the battery energy control module must report ready within 30 seconds. GM's general circuit code for the same line is P0E65. CARB requires detection of charger faults that block charging or reduce its rate. Pure wiring faults are P0E65 to P0E67; a software update is often the first step.
