# Service bulletin SIL 790

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10189945
- Published by NHTSA: 2021\-04\-06
- Manufacturer's number: SIL 790

## NHTSA's summary

It has been discovered that some hydraulic lines installed by Altec may be in contact with chassis air brake line\(s\). Some DOT inspections have considered this to be a violation of federal regulation 49 CFR § 393.45 b 2. Over time, chafing of the air brake line\(s\) could result in loss of air pressure and reduction in braking performance. Altec requires the routing of the hydraulic lines to be inspected no later than the next periodic maintenance interval. The affected unit are some T40P cable placers installed on Ford F750 chassis from May 2015 to January 2020

Some 2020\-2022 F\-Super Duty vehicles equipped with a 6.7L engine may experience a lack of power due to snow packing of the engine air cleaner when operating in extremely snowy conditions. This may also be due to ice forming in the air intake while operating in temperatures below \-22°F \(\-30°C\). Diagnostic trouble code \(DTC\) P1548 may be present in the powertrain control module \(PCM\). To supplement heavy snow environment pre\-filter service kit \(service part LC3Z\-9K635\-AA\), a front grill cover \(service part NC3Z\-19A413\-A\) is now available for service but is not a warrantable item. It is recommended that the front grill cover be removed at temperatures greater than 10°F \(\-12°C\) and reinstall in subsequent winter seasons in order to maintain optimal vehicle performance.

This may be due to a stuck/binding temperature door within the climate control housing or binding/inoperative temperature door actuator. Diagnostic trouble code \(DTC\) B1081:07 may be present in the front controls interface module \(FCIM\) or heating ventilation and air conditioning \(HVAC\) module. To correct the condition, follow the Service Procedure to remove the climate control housing and replace the temperature door cam\(s\), lubricate the temperature blend door bearing surface, and apply flock tape to actuator to seal out debris.
