Anti-thief light flashes and dashes on odometer
My 2010 4.0 ranger needs your help. I had to replace timing chain tensioner and cassette. Also had new valves and had the heads redone. Put everything back together and then the anti-thief light came on and couldn't get it out of no start mode. Had 2 new keys made and reprogrammed still nothing.replaced the transceiver, no start. Finally I was wiggling the fuse box inside the engine compartment and all of a sudden anti-thief light went out and I was able to start. It was missing real bad so i disconnected battery to check timing was right. It was . connected battery and anti-thief light was blinking again and had dashes on odometer. No start again Checked all my grounds,checked fuses and relays nothing.anyone have any ideas that can help.please its been 3 weeks of hell trying to find the problem

Or possibly a low battery, is it fully charged ?
Also 1 thread about your problem was enough, you now have 4, you're just going to **** people off and they will ignore you.
Turn on the key
THEFT light flashes rapidly
Leave key on
wait 45-60 seconds and THEFT light will start to flash a 2 digit code number, telling you WHY PATS was activated
first digit is always a 1, so 1 flash, pause, 1 to 6 flashes, longer pause, repeat
11 Transceiver [transponder coil] not connected, or there is no power to it.
12 Transceiver internal fault.
13 No Key/no PATS key has been used to turn the ignition switch.
14 Incomplete key code received.
15 Invalid key code received.
16 CAN communications error.
In 2004 to 2010 Ranger's PATS module is in the Cluster/digital dash
The dashes on Odometer could mean power issue at the cluster or no communications with PCM(engine computer)
There is no connection between engine work and PATS, PATS only cares about the Key's number
You could pass PATS key test with no engine in the vehicle, lol
About the only connection would be the 12volt and ground wiring in the engine bay since that's where ALL 12v and Ground come from, the 2 battery terminals
Since its been 3 weeks I would just "bite the bullet" and get a Mobile Mechanic who has experience in Ford PATS and electric issues to come out

I'm getting code16. It has done this before right after I replaced everything and put back together. I had a locksmith come and reprogram 2 new keys,but still couldn't get the anti-thief light off. I ended up towing truck to my new house and started messing with the engine fuse box and suddenly light quit flashing and was able to start the truck. Tried to start it the next day and anti-thief light was flashing again with code 16 and now odometer has dashes.What else could it be if not ground or battery?

PATS code 16 "CAN communications error"
CAN = Controller Area Network, aka can bus
This is a data network in the vehicle, same as a "home network" but only needs 2 wires at each module(see diagram)
Code 16 in this case means the PATS module(in the instrument cluster) can not talk with the PCM(engine computer), as those are the only 2 modules needed for PATS
It DID NOT use codes 11 to 15, which means transceiver is OK, and the Key that was in the ignition was OK, so the codes NOT USED are as important as the code that was used, this applies to ALL vehicle codes, not just PATS
Can Bus Error doesn't always mean a wiring issue, could be one of the modules is not powering up "on time" or at all
Instrument cluster uses CAB fuses 9, 10 and 33, 9 and 10 should have 12v key on, fuse 33 should have 12v all the time
The above fuses are powered by ENGINE fuse box fuses 3, 5, and 9, these should all have 12v all the time
You have what Ford calls an HEC(hybrid electronic cluster), it has a micro-processor inside, and it can be tested
Google: HEC test mode
Read the PDF and watch the videos
Have camera ready as the Odometer display is used to display Body codes(B), and chassis codes(C), and data codes(U) they can go by pretty fast
Watch the CEL(check engine light) on the dash
CEL should come on almost instantly with key on, CEL ON means PCM(computer) has booted up, if PCM is not booting up or is slow then PATS will set code 16
PCM is powered by Fuses 11, and 21 in ENGINE Fuse box
Also PCM Relay in engine fuse box
If PCM is not powering up then code 16 and "dashes" in Odometer display

I'm trying to figure out how to get the anti-thief light off and the odometer right. I was testing the fuses in the engine fuse box and I have found fuses#21,23,25,27,31,and 33 with key off to be hot. Is this right or is there a short somewhere?

Anti-thief light flashes and dashes on odometer
I'm trying to figure out why truck won't start and am checking fuses in the engine fuse box. As I'm checking fuses#21,23,25,27, 31 and 33 are always hot. Is this right? I'm wondering if there is a short somewhere. HEC test results show code saying ABS module has a problem. Is this the reason im getting code 16 and the PCM triggering the anti-thief light and odometer dashes?.

Dashes on odometer
Still can't figure out why my truck won't start. Supercab gave me good info to check and I have done everything he suggested. The HEC test gave codes DTC 9352,9601,c100 and C121 can anyone give some suggestions to look for?

Just keep in mind... we're all unpaid volunteers here.
I don't think you are going to be able to solve this issue externally
In my opinion best step forward would be to get a Mobile Mechanic or Mobile Locksmith that has Ford PATS experience to come out and hook up a laptop with Ford software to the vehicle, then they can determine where the issue is coming from
It could be a computer(PCM) fault or PATS module fault(dash) both of which can't be swapped out by you and are expensive to just swap out on a guess

Thanks Ron, I appreciate the advice,but I live in a very remote area in the mountains and there is no service available like a mobile mechanic. I have had a locksmith come out and reprogram 2 new keys and hook up to a computer, but that didn't slove my issues.

I think the fuse box needs a thorough inspection
