22. What about after the repair? Anything to do?
All you have to do is reinstall your module and you are set! Just PLEASE ensure that all three connectors actively click into place on both sides of the connector. The back one nearest the firewall, especially, tends to give people the most trouble.
Once the truck starts again, use the opportunity to verify that the batteries are maintaining at least 11.8 volts right after startup and that the alternator is putting out 13.6 or more volts to the batteries (after the glow plug cycle is complete) to avoid having a repeat issue.
