"Neutral Tow Enabled" Constant Message

[TheyCallMe]

Thank you @RangerBill!!!!
There is continuity between both plugs on both sets of wires.

What do you guys think? (guys?)

At this point we're between the C1035B connector and the "3" leg of the relays. I would expect that to be a jumper, and it be really odd that both of those jumpers would have some type of an issue, at the same time. no... that's true, these will go through the NC side of the relay to get to ground on the 4 pin of the relay.

Long story short, the one OE relay that was in the CCW position was only a 4 leg. the one I "replaced" the aftermarket one with, was also a 4 leg... Swapped 5 leg relays into both positions and I have continuity at the plug to ground but still no shift power.

Rechecked fuse 66 on the bottom of the BJB and it was blown. I'll get one tomorrow after work.

Here's my thoughts on what has happened. When the guy shifted it to 4wd, it had the 4 leg relay in the... shifting TO 4x4 direction. When he tried to shift back, there wasn't a ground on that relay to complete the circuit. And at some point the fuse blew...

I will report back at ~5:15 tomorrow....

Thank you both for your help up to this point.

You are correct - The 4 Pin Relay will not have the (At-Rest) Ground Pin noted as Pin #4

Played Today - To find the specific position readings from the feedback sensor on the motor and wanted to find (Neutral Position) Electrically as it is not shown in the diagrams.
Also confirmed - that the CW & CCW Relay's (match the switch movement)
As when rotating the switch CW - The CW Relay (Triggers ON / Off) the CCW - Holds Off
Opposite for the CCW Relay.
Note: The Relay (Off/On) Status would be the PCM (Coil Ground) Signal of the relays
The attached pic is a all-inclusive readings for the positions as noted

I believe once the problem with no voltage being supplied to the shift motor is solved, the sensor feedback voltages will fall into place.

Agree - But wanted a deeper ref point of normal readings that the manual leaves out.
Mainly wanted to know where mechanically & electrically the motor position rests in Neutral.
So, the 5-Volt (VREF) drops down as the motor moves CW. This is the feedback position of (Pin#2 on the T-Case Motor)

@airline tech thank you so much for those position values. They saved me here.

I got home, replaced F66 which is apparently a ford only part. luckily there's a ford dealer in town and they had them.

Still had the "neutral Tow" fault so I hooked up for scan to read the values. 2.0v...
Went over to the window of my shop so I could get service to pull up your data, and saw that 2wd is 4.0v...... "I bet the motor is 180° out..."

Pulled out the shift motor out and noted orientation with a paint pen. Key to run. Tap the brake. Relays click. Motor Spins. Forscan indicates 4.0v. 2H light illuminates on the shifter...... Hell yeah....

So, when my builder power probed it, he either went the wrong way or multiple round and ended up on the wrong side.

Thank you for all the help on here. It sure made birddogging this much easier.

I hope I can repay the forum back over time.

Case closed - G

I love closed cases.

Awesome News, to add to the thread for future member issues:
I threw this together - I think the manual positions are near correct and guesstimated the position of the internal shift lever as it would rotate CW using the known voltage data as a reference guide.

For it being 180 Out - Yes, I can see that, as it was (Power Probed) with the motor disconnected and it would not have a (Commanded Stop)
The ones I have replaced in my career had markings of position indication on either the case or motor. The Ranger does not have that luxury.
