PROBLEM

The existing (271-2105, 338-5365) sensors used on 793F Command and Command ready Off-Highway Trucks may fail resulting in steering position sensor malfunction event codes that can cause the truck to stop during autonomous operation. The sensors have been replaced by an improved sensor that no longer requires a trim file calibration and has improved internal components, which will reduce failures.

 NOTE: This is a 0.0-hour job
If there has been a previous repair, part age/hours will apply. Retain a copy of the previous repair invoice in the dealer's records for audit purposes, and specify repair date and machine hours in the "Additional Comments" section of the warranty claim.

This program is intended to be implemented at PCR (expected 15,000-20,000 hours), so no labor will be allowed at PCR or before failure.

If there is a failure, both cylinders must be rebuilt. AVSpare will pay 29 hours of labor to rebuild both cylinders. For these after failure repairs, dealers must upload a recent product status report showing valid steering events.

Note A: These parts are required, but are not covered at PCR.
