Initial issue
Status Indicator RAPs
7-250 Tray Communication
Communication fault between Tray Module PWB and MCU PWB.
Procedure
+5 VDC is measured at P/J541-9 on the Tray Module PWB.
YN
0 VDC is measured at P/J541-9 on the Tray Module PWB.
YN
•Go to Figure 1. Check all of the wires between the Tray Module PWB and the
MCU PWB for an open circuit. If the check is OK, replace the I/F PWB (PL
13.1).
• If the problem continues, replace the Tray Module PWB (PL 16.15, TTM) (PL
15.9, 3TM).
• If the problem continues, replace the MCU PWB (PL 13.1).
• If the problem continues, replace the ESS PWB (PL 13.1).
Go to Figure 1. Check for a shorted wire between the Tray Module PWB and the MCU
PWB.
•Go to Figure 1. Check for an open circuit between P/J541-9 and the MCU PWB. If the
check is OK, replace the I/F PWB (PL 13.1).
• If the problem continues, replace the Tray Module PWB (PL 16.15, TTM) (PL 15.9, 3TM).
• If the problem continues, replace the MCU PWB (PL 13.1).
• If the problem continues, replace the ESS PWB (PL 13.1).
