Hello everyone

My ranger gave out this morning. It was starting and running fine. Came to my local Junkyard and it wouldn't start back up. The battery voltage is 12.6, the terminal connections were a little loose but didn't solve anything after tightening them. Also briefly checked out other connections.

Someone offered a hand and got it cranking by using a screw driver and touching the two starter connections. Nothing. Just cranked and cranked.

The anti theft light flashes repeatedly on the ON position. It blinks faster than I remember. So I hooked up my handy scan tool and got codes

B1681
B1359

I have two working keys for the ignition and one for the doors. I got an extra after losing the keys at work which I ended up finding the nest day lol.

I've used the extra key for the ignition for over a year now no problems until now

Any ideas guys?

 

I have not tried the original key. But I will update when I do

 

Tried the other key with no luck

 

The Flashing Theft light is the reason for the no crank/no start

Did you look up the codes?
If so post the definition with the codes

B1681 - PATS Transceiver Module Signal Is Not Received
B1359 - ignition run/accy circuit fault

What Year Ranger?
And engine size may matter as well?

This could just be a blown fuse but need the year to look it up

The Transceiver is powered with 12v from ignition switch via a fuse
And the B1359 code means the GEM or SJB didn't get a "key on" 12v signal, again year matters, could be the same fuse

So both codes may be related

Generally, 25amp fuse #19 in cab fuse box was used for PATS anti-theft

Always include Year of Ranger in posts

 

Yes I did, I apologise as I'm in the middle of figuring this out going back and forth 30 min driving.

It's a 02 3.0L I'll check the fuses when I get there

 

Fuse 19 is fine. Had to get the truck towed.

Any other ideas?

 

2002 Ranger used fuse #19 as well, did you swap it out, or test it with OHM meter, "looking" can't tell

If fuse is OK then most likely issue will be the transceiver has gone bad, not common but not unheard of either

And just a heads up, if you attempt to start engine 3 or 4 times and Theft Light flashes fast each time then computer goes into Lock Down and it will not start even with correct key for 30-45minutes.
Best thing is to disconnect either battery cable for 5 minutes then reconnect, that should reset immobilizer, not always.

Wrecking yard should have matching transceivers, 2001-2002 should be the same, Ranger, B-series and Explorer SPORT
Part number is 1L5Z-15607-AA

 

Yes Ron, I even swapped out the fuse.
I took off the steering column covers and found the part you mentioned but the part #s differ. I'll make a quick run to the pick n pull in the morning.
I won't have to reprogram anything or pay someone with a fancy scan tool then?

The part # on mine is 1L5T-15607-AE

 

Same thing happened to mine, unfortunately my dumbass didn’t realize that the terminals had corrosion. $100 later my local mech had her going good again. I was running luggage back and forth after I got back from a vacation and started her 5 min after shutoff and dead nothing. It’s not that uncommon, happened to a buddy of mine too

 

No, the transceiver is not specific to the system anti-theft system, just a generic part, and can be swapped without any reprogramming

Yes, that 4 wire connector can fail as well

 

Thank you Ron, I swapped out the part this morning after a quick trip to the junkyard and $14 later she fired right up.

I didn't come across any with the same part number you mentioned, but it still looked identical. Replaced it with the same part number from my truck and all is well now :)

 

Good work

Thanks for the update and FIX
