P2E38Battery Charger B Enable Circuit Range/Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E38 flags an enable circuit of charger B that is electrically sound, while the charger or its partner modules do not react to it as expected. No manufacturer documents P2E38 publicly. Ford shows the A-side logic for P0E64 in its 2019 plug-in hybrid OBD summary: once the charger is ready and the wake-up line Chrg_Wkup is high, the battery energy control module must report ready; if it still says not ready after 30 s, the test fails. Slow start-up, a module that does not wake or mismatched software can therefore trigger the code without any wiring fault. GM's 2019 hybrid tables check the hardware side of the line separately (P0E61). CARB asks for rationality checks where feasible. Circuit faults are P2E35 to P2E37, output power deviations P2E3A. Charging may start late or not at all.
- What you may notice
- Charging begins only after a long delay or not at all
- Fault appears only on some charging sessions
- Likely causes
- LikelySoftware mismatch between charger B and battery control module
- PossibleBattery control module not waking or starting too slowly
- RareEnable level marginal due to contact resistance
