the auxiliary functions like tilt and reach and side shift run off the auxiliary hydraulic function that is controlled by the main hydraulic controller. auxiliary functions use the main hydraulic pump at a reduced speed using a separate control solenoid in the hydraulic function manifold 1, the auxiliary function control circuit is then enabled for manifold 2 (located at the carriage) when an auxiliary function such as tilt, side shift or tilt is selected.
Main lift and lower are a separate circuit off the main hyd controller using a specific solenoid valve on the manifold 1.
Both auxiliary and main hydraulic functions are both originated at the main control handle. The information is gathered from the display unit controller and is distributed via the CAN bus to both the valve and pump controller.

Fixing the wire in the mast control cable wires did fix the auxiliary function control out to the manifold 2 at the carriage but it seems you still have an issue somewhere between the control handle, display unit and main manifold 1 solenoid's that control lift function.
