    Fiat 500e Remote Service in the United States

    Fiat 500e Remote Service in the United States, begins with one of the biggest messes I have ever encountered. Jon sent me a n e-mail with dashboard photos of almost all possible errors appearing simultaneously on his 2013 500e. His main concern however, was repair for “Not Ready,” perhaps the most dreaded error of all. John admitted that he had already searched all sites and forums of 500e owners. He had tried a great many ‘fixes’ with no results for any of the errors.

    Initial problem list, posted by John was:

    • “Not Ready” immobile vehicle – with flashing odometer
    • “Blue and Me,” steering wheel buttons, and USB not working
    • AlfaOBD Body Computer error B2204
    • AlfaOBD errors TMPS U0019 and C1001-4
    • There is a postal letter envelope icon above odometer -origin unknown.
    • Level 1 EVSE not charge, with two outside dashboard lights flashing.

    Jon had OBDLink MX+ code reader and registered copy Android AlfaOBD, so I immediately asked him to send me the HV Battery Log. This’s the basis for servicing an electric car

    Alfa’s OBD Battery Log reported few issues, except for the lack of the correct signal to switch the contactors and the lack of charging for the 12 V battery. This is a list of common problem for people who press “everything” in AlfaOBD. But for further diagnostics, I needed logs from other powertrain ECUs.
    Unfortunately, Jon had issues that prevented getting additional logs. The situation was getting weirder. Using one trick, I was able to resolve the “Not Ready,” and get the Fiat 500e up and running. But not everything was working properly. Even though the car was already in the “Ready” state, the 12V battery was still not being charged.

    Most troubling now was the number of errors in CAN communications, in addition to low 12V battery charge, ABS/RBC failure, and ECU configuration mismatch.

    With no possibility to generate logs from several ECUs, I decided to put AlfaOBD on the shelf, and switch to the native 500e diagnostic tool: WiTech. It enables immediate connections to all modules in both CAN networks, giving a better and more reliable overview.

    And so it was in this case. Upon WiTech connection, the diagnosis appeared immediately. I was then certain that the Fiat 500e Remote Service in the United States would be a complete success. which is confirmed by a very nice entry and 5 stars from Jon on Google

  • Fiat 500e Loss Of Insulation

    Fiat 500e Loss Of Insulation

    Fiat 500e Fiat 500e Loss Of Insulation. What is it and what is it for. In every electric car, the High Voltage (HV) installation is fully insulated from the 12V installation. The frame of an electric car is not a mass or a downside High Voltage (HV) installations, as it almost always happens with internal combustion cars and 12V installations.

    Fiat 500e Loss of Insulation (LOI) occurs when there is a violation of the separation between the high voltage system and the low voltage system of the vehicle.
    In the Fiat 500e, the high-voltage system is isolated from the 12-V system. The resistance between these points is calculated based on the energy potential of high-voltage systems (battery pack voltage). The higher the voltage potential, the higher the resistance (insulation) value.

    Fiat 500e Loss of Insulation can be associated with one of the following high voltage installation modules:

    Electric heater (AEH)
    Power Inverter Module (PIM)
    On-board charging module (OBCM)
    Electric drive motor (EDM)
    High voltage battery system (HVBS)
    Electric air compressor (EAC)
    Battery coolant heater (BCH)
    High voltage energy distribution center (high voltage PDC)

    Fiat 500e body insulation test, Insane equal to ZERO Ohms.

    The described patient came to our Electric Cars Service on a tow truck from outside the province. Unfortunately, before falling into the hands of some amateur, because of the cost of tow trucks and the desire to save. Fortunately, it didn’t end in a serious accident. Fiat 500e diagnostic tools are not only to delete DTC’s and Fiat 500e Loss Of Insulation Fault is the best example. Bpcm HV battery insulation test results:

    2013 Fiat 500e body insulation test equal to ZERO Ohms means a high voltage short circuit with the car frame. Measurements made with the voltmeter confirm the diagnosis from the computer. Over 200V between the ‘+’ HV installation and the car frame. Fortunately, the car’s safety systems worked, causing it to become immobilized. Otherwise, if it were enough to clear the errors and start the car, driving it would be like groping in cables protruding from the wall or in a home fuse box.

    Fiat 500e Loss Of Insulation. Bloody short circuit in high voltage installation

    Diagnosing a short circuit in a high-voltage (HV) Fiat 500e installation begins with a visual inspection of the entire car. The initial look shows the rich service history of the Fiat 500e and what you can see at first glance, unfortunately LITTLE PROFESSIONAL !!!

    despite the lack of visible obvious cause of the problem, the list of potential is growing every day.

    The real hits start when the HV system modules are dismantled, which we always start with draining the coolant. Tanks at the top full of pink, blue fluid (typical colour after mixing with a typical Polish fluid) from the unscrewed tap under the radiator does not even drop a drop … Attempts to start the water pump despite checked fuses and forced command from the service computer do not bring the desired result …

    The water pump is only started for the first time after the installation of the ‘new’ Fiat 500e on-board charger (OBCM). Unfortunately, this substitution has no effect when it comes to puncturing high voltage installations. Could another hard-boiled module be an inverter (PIM)

    An additional small body test using a micrometer explains a lot about the car’s history and potential causes of the problem. In addition, it suggests one more potential cause of the problem of Fiat 500e Loss Of Insulation

    repainted the whole side and the post … and it was probably welded …

    we check every cable, every element of the system. The amount of things that raise our concerns is bursting at the seams.
    We do not even like the 12V battery, which is not a lead type A1 battery only A2 for the START / STOP function in combustion cars

  • Solving not ready no faults codes Fiat 500e

    Solving not ready no faults codes Fiat 500e

    Solving not ready no faults codes Fiat 500e. Last Friday evening got a call from Alexey from drive2.ru forum with Fiat 500e problem that was left for few weeks not used. 2015 Fiat 500e without U69 recall update, with dead 12V battery, not ready and not charging = over-discharged HV Battery. But where is the red turtle. With over discharged HV battery we should have at least “BPCM Fault” diagnostics trouble code on OBCM and PIM. In this case Alexey’s AlfaOBD running on ELM327 wifi shows no active faults/trouble codes.

    First fast look at HV battery data shows not a HV Battery based problem. So after i have asked Alexey to perform 12V Power Down Procedure for half an hour to reset Fiat 500e i check logs from EVCU, OBCM and one more time back to Battery Pack Control Module log. Despite my almost 100% certainty, the “30minutes, 12V power off procedure” didn’t solve the problem. The situation is getting stranger every moment.

    A closer look at battery data shows one stored problem that currently run & passed this cycle. It was car & battery Loss Of Isolation problem. We have reset isolation check fault with no resolutes again.

    It takes me about two or three more hours to solve the problem. Which is quite bad time for this kind of problem. But on the other hand i have only AlfaOBD logs without remotely access to Fiat 500e with WiTech diagnostics program that i’m get used too.

    During any service works on Fiat 500e, remember to remove safety plug !!
