P0E6DBattery Charging System Precharge Contactor Control Circuit/Open
- Generic OBD-II code · Powertrain
- How the car detects it
- P0E6D concerns the low-voltage side of the charging precharge contactor: the coil circuit through which the control unit switches it, typically interrupted. Unlike P0E6C, which judges what happens on the high-voltage side, this code comes from the driver output itself. No manufacturer documents P0E6D publicly. GM uses the same method on the positive charging contactor of its 2019 hybrids (P0D0A): an open is recognised when the switched-off output still shows more than 4 V, or when less than 194 mA flows with the output on; 40 failed samples out of 50 at 12.5 ms set a Type B code. Mitsubishi's i-MiEV compares a coil monitor with the command and stores P0AE6 for the charging contactor. Range, low and high faults of the coil circuit are P0E6E to P0E70.
