- Summary
- Some customers have reported the loss of functionality of the Altec unit or the EZ Trac system on certain 2016-2021 Ford F750 chassis with EZ Trac hydraulic all-wheel drive installed. The investigation has shown that improper wiring could have been installed for the PTO request module that interfaces the EZ Trac system with the Ford system, leading to the loss of functionality. Altec requires the vehicle to be inspected no later than the next preventive maintenance interval or 90 days from the receipt of this SIL, whichever comes first. If the inspection reveals nonconforming operation, the vehicle must be repaired by both an Altec technician and a Terra Drive Systems technician working together. This inspection and repair are covered under the Altec Warranty Policy. The inspection can be performed by Altec, the customer, or the customer’s warranty provider
