So I’ve had a tac 20 go out on me every 2- 3 weeks. It shows viscosity on the car status but is not running the pump. There is an 1155 fault logged which is not in the book for tac 20s but it gives a short description of INIT SD MCE/MCD in remote fast. Will not start working with a reset or pulling the hook but will start working if you put it on inspection and then back to auto. On the 1155 fault the Dvel is showing 149 fpm while the Cvel is showing 0. Hours after the 1155 is logged it has a 1042, and 1103. Car status shows viscosity and group shows normal. Aribiter shows

motion 20: viscosity
Calls 20: viscosity
F door. 20: viscosity
R door. 20: viscosity
Speed. 0: automatic
Lockouts 0: automatic

Automatic 2: no calls
Viscosity. 3: shutdown

It’s alway found in the basement
Any insight would be appreciated
