My name is ***** ***** I will assist you with your concerns.
Freightliner doesn't do last 6 of VIN anymore. Now they are doing full VINS because the VINS are duplicating on their new trucks. At least my access doesn't. Can I get full VIN or the model so I can look them up?
Where are you needing the diagrams for? What valves?
Customer: replied 2 years ago.
Vin# ***** need the treble valve and the tractor protection valve, air lines diagrams. Replaced the treble valve, protection valve and the parking brake valve. Have air bleeding back into the system. Need to make sure i don't have a couple hoses hooked up wrong. Thank you

This link will have everything you need for every valve, line, and troubleshooting for the valves. You can check every valve behind the dash, the routing for the treble, etc. It will even explain how to test.
Freightliner is purging this off of their website soon. Make sure to download this for the link will become inactive in 7 days. Thanks.
