HELP with Resetting Proximity Parking Sensors

Hey all,

I made several mods and upgrades to my 2019 Crewmax last week. In doing, so I removed both Front L&R Bumper Sensors for a few days while I painted the Bumper Caps.

After putting everything together I noticed a Dash Alert flashing ALL six sensor positions. Of course, I came here first to see what others had done and/or recommended. So far nothing has cleared this issue.

FYI, I have tried the following steps before asking help here:

1.) Disconnected the battery for a couple hours (while working on other things)

2.) Inspected Front Sensor cables and connectors for proper connection.

3.) Driving truck for several days to see if Warning would clear on its own.

4.) Powered Off the Parking Sensors and back On multiple times at different time intervals.
When the Parking Sensors are turned back on the Warning is cleared for a minute or so. Then the two Front Sensors warnings flash, followed by all six flashing again about 30 seconds later.

Is it possible that a Scanner needs to be connected to clear the faulty Error Warnings?

 

Check all the connections to the sensors, maybe they’re not connected correctly or something is bent.

I had all mine disconnected at one point when I installed some after market lights and a grille and never needed to reprogram anything.
