For a true parasitic draw test, you need a good (Low Amp) Probe that can read low current. This is what I have and used in my testing It will read as low as 1 mA - expensive but works great Ref my chart above for expected (normal) readings - far less than the Klein will show for any true...

As stated above check connector for bad contacts and wire harness for damage, non oem sensors have been noted as problematic as well (cheaply made and nonstandard specs) Plus - pull the sensor and look into the hole and check the encoder ring for any debris or damage on it while rotating the...

Relays - (Here are the relays) Non- Serviceable and integrated into the BJB The BCM (controls) the time out feature and uses the (Set & Reset) to do it and it is also used for circuit monitoring To clear things up (Voltmeter) This is the voltmeter we are referencing - not take a meter...

You may try pulling the TCU fuse for 5 minutes and also delete and reinstall the ford pass app after the master reset - it’s the TCU that’s locked to the previous owner that needs the updated information of authority authentication

A .2 volt drop across the relay would be normal , that’s what you would see on the power point

The reason is - different thresholds for th e message vs disable remote start functions (via Ford Pass) The Power Points - should not cause this type of voltage reaction - it should be a constant draw, however if the dashcam has a (Park Mode) feature I wonder if the cam is shutting off and...

I will need to do some (On=Truck) testing to see if my BCM acts the same way, if you are having battery issues and it has a history, I think the AMP install is just highlighting what the BCM has been doing behind the scenes. Being you mentioned - Dash Cam, unhook it - and see if you get the...

You are highlighting something here that - I need to dig deeper into and that is the BCM control of power from the interior fuse box. The Factors 1. Testing with the door open - try latching the door lock, closed to simulate the door being closed. This I believe may be part of the reason you...

To CONFIRM - The fuse tap is only for the (Remote Turn On) correct? and you are powered separately? The remote turn on does not take much current (about 5 to 20mA) to trigger the turn on and the BCM does not see enough load change at key off - to shut the circuit down and it keeps it alive. I...

As Ranger Bill asked - where are you tapped? plus what trim do you have - The B&O or non-B&0?

I would say it's not worth repairing - too many wires damaged across multiple circuits and leaves multiple paths for circuit failures down the road. That is the main engine harness (Harness # 12C508) It should have a (Service Tag on it - KU5T-12C508-(??) (possibly -ALA) This converts to Ford...

I see one potential issue and that is the PCM is being told it’s in 2-Hi (commanded) and you have it locked in (neutral) mechanically - the PCM will see the mismatch and try to drive the motor to correct position and blow the fuse - so you would still have to have the electrical command for...

The most important is to do a Live Data Monitor and see what the Fuel Trims are at Idle and Cruise also record the MAP and O2 sensor readings This will provide an indication on what is actually happening with the fuel, and it depends on what they are reading. I posted this awhile back for some...

I was playing with Ideas and have found a possible solution for uncommand shifts If we look at the motor (pins 4 & 5) and follow the (relaxed) state logic you will note 1. Both wires are connected together 2. They both are running to chassis ground The (Motor Brake) is not provided from the...

I would check the following: AC Pressure Sensor (PID) - the request may be being sent and raising the RPMs but the pressure sensor is keeping the clutch disabled When you checked for the AC Pressure was it with an external manifold gauge set or this PID? If only a gauge set, the sensor may...

For a cleaner explanation I dug a little deeper and now Scenario #1 - makes sense The low voltage drop-out (Brownout) and then recovers When it recovers - the BCM and PCM treat this as a (Wake Signal) - (this is how the PCM powers) and where I was hung up on how it was able to get power and it...

While to do it right can have some shortcuts implemented if using the old rotors, it mainly depends on if you were having (pulsating pedal) issues or vibration issues when braking. The decision is based on what does the rotor surface look like and what do the off pads look like If there are...

ok so it's not an actual detent position its merely using the T-Case motor (Tension) to hold its position. I cannot place an actual cause (progression) on what actually happens but if we follow the power path we can see 1. The PCM Power Relay - Must be closed for the Transfer Case (4WD) relays...

Hopefully they find it - It sucks losing hardware. Not down the tube of course but sometimes it helps to get one of the matching bolts or screws etc and actually drop and watch - normally it will drop in the same area (hidden location) Just a mechanics (little trick) or use a blow gun that also...

Yes, as the TRM is detecting a load from the Stop / Turn circuit, I suspect it may generate with a Turn Signal as well - Triggers the - Trailer Connected The reason I stated that the (ZCI) sense wires must be connected to (Actual Circuits) is that yes, you have voltage on the TRM feeds to the...
