Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello. My name is ***** ***** I will be helping you today.
How much of a draw does it have?
Try unplugging the keypad on the door and see if it still has the random spikes
How long are these spikes lasting? The PCM is the only other thing running off that circuit... may have something waking up the PCM (a door switch or something)
How long are you waiting before checking for a draw?
OK. Just making sure you are waiting long enough. This one needs at least 45 minutes to an hour for the modules to go to sleep.
Have you load tested the battery? A bad battery can and will cause random spikes like this? If you havent yet done that try now or try a different battery if you have one handy.
The next step would be to try it with the alternator disconnected.. it too can cause this.
Considering you have disconnected or replaced everything that could affect it I am at a loss. Im gonna opt out and see if another expert has any experience with it. Without being able to check it myself I have no other answers for you.
Fuse #5 in the SJB powers more than the keyless entry and the shift interlock. I need you to look at the diagram below of the SJB and unplug one connector at a time that I listed below and see what connector stops the draw.
Please keep me informed. Also, if you can give me the VIN# ***** the mileage, I can contact a resource we use at the dealership called Hotline.
Sorry, I work during the day at a Ford dealership as a technician and getting on line during the day to answer questions is next to impossible. I only get on this web site in the evening.
Since the draw goes away when you unplug connector C2280D, see if you have a trailer harness connector on the back of the vehicle.
Plug the connectors back in and unplug the trailer tow right turn relay and the trailer tow left turn relay in the engine bay fuse box. Below is a diagram or the fuse box.
We are narrowing it down.
And none of the other fuses in the SJB effect the current draw?
Even 10 mA is too much per Ford specs.
This is odd. Unless something is back feeding the circuit. Below is the diagram I am looking at.
The bad part of connector C2280D is that is has up to 32 wires in it.
Did you let the vehicle sit with the meter on it for up to 45 minutes for everything to power down. Some of the modules take that long to finally power down.
Are there any aftermarket accessories on the vehicle like an added on alarm, radio, amps....?
I put a request for help to a friend of mine in Dearborn. I will not hear back from him till tomorrow morning.
I am still looking over the diagrams tracing down all the circuits and where they go. It is easier if I could put my hands on the vehicle and actually test it myself.
Below is what he mentioned for us to check.
C466 is on the subwoofer amplifier.
Let me run this new info past him. See what else he has.
Still have not heard back from them. May not hear back till Monday. I'll try to dig up the circuits in that connector.
Read the report below. Also, did you program the SJB to the vehicle?
Please keep me informed. Also, if the SJB is not programed, the dome lights will flash on and off with the key on and the TPMS (Tire Pressure Sensor) fault will display on the instrument cluster.
What makes you think the TPMS is at fault?
See the instructions below.
