Been working on this off and on for the past week. Code 112 is HGTS1 inputs to Access1 and 3 not matching. Followed guide and wound up replacing HGTS1 switch based on results of A2.1.4 and A2.3.4 test results. This improved the problem from happening immediately on startup to now only when mast rises above staging. Finally tried swapping access3 over to a known good lift but lift wouldn't complete startup. Swapped distribution board but problem did not follow. Suspecting Access3 but uncertain how to confirm or whether it may be Access1. Any help would be appreciated.
