P0D26Battery Charger System Precharge Time Too Long
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- How the car detects it
- P0D26 means the charger's high-voltage bus did not come up to battery voltage within the allowed precharge time. GM's Volt 2011 to 2015 and ELR 2014 to 2016 require the bus to sit within 5 % of pack voltage for 0.25 s before 10 s have passed; the 2016 and 2017 Volt allow only 0.700 s to reach 95 % (later 95 to 105 %); all are One Trip Type A. Mitsubishi's Outlander PHEV looks at the charger's own capacitor, which must charge to 120 or 240 V within 45 s, otherwise charging stops. Bulletin PIP4905E links P0D26 on the Volt and ELR to no charging and asks for HPCM2 software, then a check of the proximity signal and charge port for water or corrosion; on the Bolt EV (18-NA-225) it comes with P0C78 when the fuse in the manual disconnect has opened. The main battery precharge is P0C78.
- What you may notice
- Vehicle does not charge on 120 V or 240 V

- With a blown disconnect fuse, loss of propulsion
- Likely causes
- PossibleOpen precharge resistor, fuse or contactor in the precharge path
- PossibleBlown fuse in the manual service disconnect (Bolt EV bulletin)
- PossibleErratic proximity signal from a wet or corroded charge port
- RareOutdated hybrid control module software
