2005 FEH 85k miles
Hi, All. I'm new to this Forum.
After I had my C-MAX for a while, my FEH stopped running and gave me an error code. I wasn't driving it often so I just parked it with the plan to fix it later. Later never came and now I'm moving and need to sell it as is. Any suggestions? It had new tires and everything worked when I parked it, but entropy has been doing its thing. The vehicle is in Houston, TX 77080 Cheers, Ed |

HV battery has gone flat.
It's important to have the jump vehicle attached and running. The HV jump starter load is high and will pull 12V battery low. Keeping the 12V system voltage high improves the HV jump starter function. |

S Keith has it covered !
left mine set and had much more work to charge (2009 is different) thats unbelievable low mileage on a 2005 (especially on a hybrid) |

FWIW, my 2005 went so low, the HV Jump starter couldn't handle it. It has a very poor battery due to abuse here in AZ. I actually had to pull the cover because the jump starter kept faulting... voltage would spike massively high and the jump starter would give up. HV battery voltage would then plummet. The NiMH was in high resistance "dormant" mode, and the only way around it is to force current through it until it "activates" and begins responding normally.
Something that was an unexpected bonus... I was able to attach a high voltage power supply to the bolts that join the relay with the main terminals. Process as follows: 12V on charger Remove safety plug Remove cover Remove small plastic cover between relay and main terminals (10mm) Attach power supply to (+) driver's side, (-) passenger side. Energize charger (<400V) Safety plug in and locked in normal position Key on/Engine off Clear codes Cycle Key of and back on With Forscan, you can watch the voltage increase and see the net current. Occasionally, the relay will disconnect. Simply clear codes and cycle ignition. I recently attempted this on a 2009+ vehicle that simply dropped a little below the start threshold. It worked like a champ with no need to reset. |
