That's the part number I bought
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 ?
I don’t think so.
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.
