Powertrain Light (wrench) light appears


Mel Eng

Recommended Posts

Hey everyone, I'm new to the forums. So I have a 2015 Sport Ford Edge 2.7L EcoBoost. I drove the car fine yesterday. I left it parked during the night and it is cold here in the east coast. For some reason, I tried to start the car and it seems like the car is completely dead. I tried to jump start the car and the interior lights and the radio and the fog lights come on but when I try to press the brake and hit the start button, the entire car dies and I lose everything. I thought it might be the battery but it has only been maybe a year and a half. When i charged the car for a little longer, I see the light gauges from the dash and one of the light was a powertrain icon. I'm wondering is this is only because of the battery being dead but I'm unsure.

 

Any help is appreciated.

Is this your DD, Mel? How many miles do you put on the Edge a day/month etc.? Just wondering if the battery gets sufficiently recharged between drives. Is it not driveable at all right now? Then definitely tow it into the dealership. They will need to pull codes from the PCM to see what might be happening. First thing they will likely do is try to charge the battery fully, see if it holds a charge, then go from there. A very few Edges have had unresolved wiring issues, let's hope that is not the case here. Also might want to inquire on getting the PCM updated to the latest calibration. Even though the engine is an Ecoboost, there's not anything Ecoboost-specific to look for in this case that I am aware of.

What are you using to charge the battery, if I may ask? Since the Edge has a battery current sensor attached, you will need to use "modern" equipment and a procedure similar to this (taken from a 2013 manual). Also will likely have to let the Edge sit untouched for about 8 hrs after to force the Battery Management System to learn the recharged battery.

Battery Charging Overview

NOTE: Batteries discharge while the vehicle is on the dealer lot or parked by the customer for an extended period of time due to normal parasitic key-off loads. Also, vehicles still in dealer inventory or in long-term storage may be driven short distances with heavy electrical loads. Over a period of time (30 days or more), this could result in vehicles having shallow or deeply discharged batteries.

The vehicle charging system is designed to supply the electrical power needed to maintain the battery near full charge during normal vehicle use. The charging system is not capable of bringing a deeply discharged battery back to near full charge in a short amount of time such as allowing the vehicle to idle for 15 minutes to "recharge the battery." Discharged batteries should be charged using an external charger.

NOTE: Battery chargers have improved greatly with the addition of the new generation pulse chargers. These chargers pulse current into the battery, breaking down the sulfation layer on the battery plates and generally reduce charging times to less than an hour.

NOTE: Cold batteries will not readily accept a charge. Therefore, batteries should be allowed to warm to approximately 5°C (41°F) before charging. This may require 4 to 8 hours at room temperature.

  1. The following chart summarizes 2 recommended methods of charging.

    Type of Battery Discharge Pulse Charger Standard Charger Deeply discharged a Follow directions supplied with the pulse charger 2 to 8 hours and may take up to an hour to accept initial charge Shallow discharge b 45 minutes to an hour charge 2 hours below (40A) on manual setting or medium automatic setting
    a A deeply discharged is a battery that is drained over a prolonged period of time, such as an unsold vehicle or a vehicle in storage, to the point the battery is dead.
    b A shallow discharged battery is a battery that is drained by leaving an accessory on for several hours or a few days and has a very low charge.

Charger Connected to Negative Battery Terminal

NOTE: When charging the vehicle battery by connecting the charger to the negative battery terminal is necessary, such as when using a combination battery charger and battery tester/analyzer, like the GR 1 190 V3.0 Intelligent Diagnostic Charger, the Body Control Module (BCM) will not immediately update the battery state of charge. In this instance, after charging, you must CARRY OUT the Battery Monitoring System (BMS) Reset using the scan tool.

  1. Connect the positive (red) charger clamp to the positive battery post.
  1. Connect the negative (black) charger clamp to the negative battery post.
  1. Charge the battery according to the battery charger owner's literature.
  1. After charging is complete, carry out the Battery Monitoring System (BMS) Reset using the scan tool.

Charger Connected to Engine or Chassis Ground

  1. Connect the positive (red) charger clamp to the positive battery post.
  1. NOTE: The negative charger clamp must be connected to an unpainted chassis surface or a solid engine component such as a generator mount or engine lifting eye.

    Connect the negative (black) charger clamp to an engine or chassis ground.
  1. Charge the battery according to the battery charger owner's literature.

I was able to get the car started after having a friend bring his car to help jump. I let it charge for 5-10 mins and it started up. Brought it right to the dealer and they ran a diagnostic and saw no errors regarding the computer but the battery was faulty which they replaced under the warranty and then they also replaced the throttle rod which was part of a recall. Finally running and it seems to drive a lot smoother.

 

Thanks everyone for the help. Only downside of this is now the auto start won't work and I'll have to bring it back to the shop..

Two weeks ago while on vacation, the "wrench'' light went on and I immediately had almost no power. I was able to pull off the road and then turned the engine off. I restarted it, it fired right up and I was lucky (in a way) that I was about a mile from a Ford dealer, so I drove there and they got the car in the shop and traced the problem to a faulty throttle body. They replaced it and everything's been fine since. All under the warranty... :thumbsup:

Throttle Rod Recall? Glad the battery's been replaced, hope the Auto Start issue is a quick solve.

Years ago, on my 1998 Mercury Sable, had it in for an oil change and they replaced the "throttle rod" on recall. They had a woman working as the service rep and she could not explain what it did, why it went bad and anything about the recall (other than it needed to be replaced).
