Computer relay check

Asked by John May 23, 2020 at 01:34 PM about the 2001 Ford F-150

Question type: Maintenance & Repair

My truck was driven into a ditch full of water and
I want to check the computer relays that are in
the engine compartment

1 Answer


Is the truck running? If you want to check all components to determine if the ECU is operating properly you will have to have a live date recorder to check every component. A mechanic shop will have one and check all the systems.
