How To Add rear Park assist

[the_nid]

Do you have the security bypass obd cable to connect to your obd?

Yes

 

[GWR Ram]

Yes

Have you had a chance to go into alpha, select Ram 1500, select Body Computer, select Body Computer My2018 Powernet, then click on Connect and once connected go to Select procedure to start, go all the way down to bottom of page and select Car configuration change. At this point start looking for the list of things to select yes on to turn your Park Assist on. If you have everything selected to yes that I sent you and it still doesn’t work, go back and look at you 2 plus connectors and MAKE sure you have the correct wire going into the correct location on the connectors.

If you have it all connected correctly and selected the settings in alfaobd and you still don’t have park assist in the rear, you might have a bad sensor or the wrong sensors.

Hope this helps.

Detest

I have the listing for "Parking" in Alfa, but there is no compatible module that matches my vehicle model year. It has listings for Parktronics Module MY2013, MY2013-17, MY2014-17 and MY2010-2012 I tried connecting to the two closest (the MY2017 ones), but it will not connect to either.

This is with the Android version of Alfa.

What would cause the front park sensors to go double red when the truck is put in to drive?

Ahh, was able to connect to it...not sure why it didn't work before. I see the faults for all sensors. The front ones are ground short (they are not installed), but the rear ones have a "performance or operation" faults. I checked the voltage on the individual sensors and they appear to be getting ~9 volts and from what I can tell are wired correctly. I have swapped out 3 different sets just to make sure that they weren't defective. When I clear the faults the lights on the front and rear park assist buttons go away, but as soon as I put the truck in reverse I get the faults back, lights on the buttons come on and message in the cluster is back as well.

Can you do a system wiring test with Alpha when connected to the park assist module .
You will see the faults for all the front sensors but will be good to see what the rear sensors have to say

I did and it came back with the same results as when I read the faults, "Performance or incorrect operation". One thing I noticed this time is that there are only 9 faults where I would expect 10, as there are 10 sensors. It appears that sensor #10 is not generating a fault? I looked at it and can't find anything special about it or its' wiring. I'll swap it out with another to see what that does.

You might have the wrong sensors.

This is what I bought

Then the park sensor itself needed four of them
Part no :1EW63TZZAA

That's the part number I bought

 

[GWR Ram]

Your front sensor light should be on until you install the sensors.

I would check the wiring again.

Where did you buy the module?

Are these oem sensors ?

 

[GWR Ram]

I don’t think so.

 

[the_nid]

I bought the module on eBay, but if it was defective I would expect to see something in the faults with Alfa. The sensors are Bosch...bought those on eBay as well.

Those are the same ones I bought and have worked great for me. I would say it is in wiring or your canbus wires are reversed.

I won’t be the can bus wires as he can connect to the module and if it was reversed the whole truck would be freaking out .
It’s either the sensor wiring like you have mentioned or bad sensors .

Pretty sure canbus is correct. I tried reversing the wires and got errors stating that the park assist was not found. I bought new sensors and will try them when they get here.

Keep us posted.

I have seen guys get bad sensors in the past here on the forum.

Got the new sensors in and seeing basically the same thing...though when I run the wiring test it's coming back with only 2 sensors having fault codes. I check the voltage at the rear harness to make sure the power and ground weren't reversed, they were not. I suppose I could have miss-wired some of the sensors out of order, but that wouldn't cause them not to work. At this point I'm wondering if the module itself is bad? One thing I did notice is that when I clear the codes and then put the car in verse up against my garage the sensors seem to come on for a split second before getting the system fault again. Though could be just nothing.
