P0D92Battery Charger Coupler Lock Control Circuit Low
- Generic OBD-II code · Powertrain
- How the car detects it
- P0D92 says the voltage on the lock control output stays too low, typically because the drive line is shorted to ground or the actuator draws far too much current, so the module cannot energise the latch properly and shuts its driver off. No manufacturer publishes this exact code. The hardware it supervises is described in patents: a small geared DC motor pushes a pin or cam across the plug latch (GM, US9279276B2), and a position sensor reports whether the pin really reached the locked end, otherwise fast charging is withheld (GM, US8936482B2). Which module drives the lock differs by maker (on-board charger at the VW group, drivetrain unit at Mercedes, SOBDM at Ford). The open-circuit case is P0D91, a short to supply P0D93; for the driver, the charging session simply never starts.
