Situation Solution
Wiring issue Check / reseat the cable between the LDM board and the LLS. If problem
persists, replace the cable.
Faulty LDM board Temporary swap two LDM boards and search for “ LLS bank x temperature
sensor open ” errors.
• If the error has swapped to a laser bank driven by the swapped LDM
board, replace the LDM board. See service procedure
“ Replacing a
driver board in an LDM unit ” , page 48.
• If the error remains on the same laser bank, the problem is with the LLS
or LLS connection.
Malfunction LLS Replace the Light source. See service procedure “ Laser Phosphor Light
