4
Checking HARNESS ASSY LVPS
Disconnect P/J141 of HARNESS ASSY LVPS.
Is it conductive between P/J141-1 and P/J141-3 when
INTERLOCK S/W 5V and SWITCH I/L ASSY 5V are
pushed simultaneously, and is not when released?
Go to step 5.
Replace HAR-
NESS ASSY LVPS.
5
Checking HARNESS ASSY ROS
Disconnect P/J14 from HVPS/MCU.
Disconnect P/J140 from ROS ASSY.
Is it continuous between P/J14-1 and P/J140-8, when
INTERLOCK S/W 5V and SWITCH I/L ASSY 5V are
pushed simultaneously, and is not when released?
Go to step 6.
Replace HAR-
NESS ASSY ROS.
6
Checking power to HVPS/MCU
Remove SHIELD PLATE LVPS. (RRP12.1)
Install EP CARTRIDGE.
