Initial Actions
• Power Off/On
• Check the operation of the MSI Guide.
Procedure
Check the installation and operation of the MSI Guide. The MSI Guide is installed correctly
and the actuator works.
YN
Reinstall the MSI Guide.
Measure the voltage between the MCU PWB P424-3 (+) and GND (-) (BSD 7.13 Flag 1).
Manually operate the MSI Guide. As the MSI Guide moves, the voltage changes accord-
ingly.
YN
Check the connections of P/J107, P/J609, P/J610 and P/J424. Connectors are con-
nected correctly.
YN
Connect P/J107, P/J609, P/J611 and P/J424.
Check the wire between J107 and J424 for an open circuit or a short circuit (BSD 7.13
Flag 2).
The wire between J107 and J424 is conducting without an open circuit or a
short circuit.
