Hello, I have a 2011 V6. My Dash info screen is giving me a "check Rear Parking Aid" message and wont beep. I checked for any "clicking sound" like many people online say but don't hear anything. I have replaced all 4 sensors but still nothing.
Next up is to look at the fuses? I think i have checked the correct ones (based on

) and they seem to be working.
finally the Parking Module correct? Have not tested this as i am not sure where it is or what to do. Any suggestions or help?
Thanks!

Welcome to the city, bustang
You are probably going to need a code reader to further diagnose. Do you have a light on the dash, as well as the message?

A lot of people like the ForScan tool

Scan the PAM for codes. Post codes and I can help.

 

[bustangadventures]

Thanks for all the help and suggestions! I will pick up a scanner tomorrow and hopefully get some codes.
Does anyone know where the PAM is actually located in a 2011?
Thanks!

RH rear quarter trim panel per that first screen shot.

 

[bustangadventures]

wow amazing! thank you so much!
Hopefully i can test the speaker as well. there is a scrapyard close by so hoping i can pull anything that i need from there! Assuming the PAM is going to be the same for all 2008-2012 escapes? I see these years often linked.

 

[bangster]

I think only 2011/2012 looking at the part number for it.

The speaker going out is common in the Fusions of the same era (2010-2012), and in the Fusion it can throw a fault like you are getting. I don't know that it is as replaceable as the Fusion as it is part of the module in the Escape, but a separate component on the Fusion.

I was able to hear them tick/click/buzzing by chocking the wheels, setting the park brake, putting the key in run/on, and putting the shifter in R, and moving around each sensor. Safest would be with an assistant, and it isn't very loud so ambient sounds can make it hard to hear.

Hi all,
I bought a scanner and the codes are as follows.
B1B48-14
B1B44-14
B1B50-14
B1B46-14
They all say there is a circuit short to ground or open. So i guess that makes sense on why all 4 wont work. I just am not sure where to go from here. I am no mechanic or electrical clearly lol!

 

[dwightbresemann]

Do you know how to use a milt-meter? I can post the tests.

 

[bustangadventures]

Hey @dwightbresemann. The basics of a multimeter yes, but not sure how to specifically test this situation. I know i sound really stupid but i have to thank everyone here for being nice about these things. I am crafty and hands on, but motors/electric are not my skill set. Woodworking is! I am just frustrated that to pass a safety on a car i have always owned (changing provinces so need a new safety) i need to sort this out. I hardly think it is a safety concern seeing as half the cars on the road in my area are old beaters with 80% rust!

 

[dwightbresemann]

Testing should be easy. Since it is all 4 sensors failing detection by the PAM, where do all 4 sensors join going to the PAM? Find connector C422 (I label it C433 by mistake), and inspect connector and wiring.

 

[bustangadventures]

Still trying to figure out how to test the circuits on the PAM connectors but am struggling to understand on a side note, I pulled the speaker off of the PAM and it has 0 Ohms reading so my understanding is that it should not be the issue. any additional info regarding how to actually test the connector would be amazing! once again sorry for being so stupid!

 

[dwightbresemann]

I'll be happy to help me get a beer first..

 

[dwightbresemann]

All tests are performed key on, engine off. All tests will be done at the PAM module. You will need a multi-meter and I recommend a small battery charger on the 12v battery while testing to keep the battery up.

All tests at the PAM will be performed with connectors attached to the module.

Set multi-meter to 20 volts DC scale and get a reading from the vehicle's 12 volt battery. Are you reading above 12 volts? Remember this number.

You can not, and will not, damage anything during these tests, So don't be nervous.

Turn the parking aid switch on. Find connector C4014 attached to the PAM (leave attached). I posted a picture of connector. Find the Yellow wire with a green stripe (pin one) and back probe the positive lead of the meter. Find the Black wire with a gray stripe and back probe with the negative lead. You should read above 12 volts.

This is the first test. We are testing for power and ground.

Report back.

Hi, I have the results. Battery is running low at 12.09 (Its been -30C the past few weeks for me and I have been running all sorts of tests). When I back probe to the best of my abilities, I am only reading 0.39..... so not even close to 12 lol.

 

[bustangadventures]

well i guess i should clarify something. There is no button for me to turn on the parking aid on. Its just a pop up on my dash that says "yes" or "no". but no matter what i do, it doesn't let me select either. it just appears for a second, then gives me an error message that i cant go back from

 

[dwightbresemann]

Yep, you have a problem. Find the positive again and attach the negative lead to a body ground. Do you have battery voltage? BTW, the .39 volts may be ghost voltage from EMF, caused by other wires in the bundle.

Also, you can run a test lead from the positive battery terminal to pin one, yellow wire with green stripe.

Are you sure you tested at pin 1 and 4? If you have no voltage or ground, you would not be able to pull codes from the PAM.

Test again.

 

[bustangadventures]

Hi, I got a better reading this round. It looks like it was reading at 11.67 at the battery and 10.94 at the PAM. I was able to properly backprobe each slot. Now what lol! THANKS SO MUCH!!!!

 

[dwightbresemann]

Now we turn our attention to the 4 rear sensors. I'll type out the testing tonight.
