Step
Checking the power to the MOTOR.
Disconnect J422 from the PWB ASSY FEED MG AIO.
21 Are the voltages across J422-6pin <=> ground on the PWB
ASSY FEED MG AIO, about +24 VDC when the interlock
switch (HARN ASSY INTERLOCK AIO) is pushed?
Checking the connectors of the SOLENOID FEED for
connection.
22 Check the connections between the PWB ASSY FEED MG
AIO and SOLENOID FEED.
Are P/J421 and P/J4211 connected correctly?
Checking the HARN TRAY COMP for continuity.
Disconnect J421 from the PWB ASSY FEED MG AIO.
23
Disconnect P4211 from the SOLENOID FEED.
Is each cable of J421 <=> P4211 continuous?
Checking the power to the SOLENOID FEED MSI.
Disconnect J421 from the PWB ASSY FEED MG AIO.
24 Is the voltage across P421-1pin <=> ground on the PWB
ASSY FEED MG AIO, about +24 VDC when the Interlock
Switch (HARN ASSY INTERLOCK AIO) is pushed?
Checking the SOLENOID FEED MSI for resistance.
Disconnect P/J4211 of the SOLENOID FEED MSI.
25
Is the resistance across J4211-1 and J4211-2 approximately
96 ohm?
Checking the connectors of the Feed Clutch (CLUTCH
ASSY DRV) for connection.
26 Check the connections between the PWB ASSY FEED MG
AIO and Feed Clutch.
Are P/J420 and P/J4201 connected correctly?
Checking the HARN TRAY COMP for continuity.
Disconnect J420 from the PWB ASSY FEED MG AIO.
27
Disconnect P4201 from the Feed Clutch.
Is each cable of J420 <=> P4201 continuous?
Checking the power to the Feed Clutch.
Disconnect J420 from the PWB ASSY FEED MG AIO.
28 Is the voltage across P420-1pin <=> ground on the PWB
ASSY FEED MG AIO, about +24 VDC when the Interlock
Switch (HARN ASSY INTERLOCK AIO) is pushed?
Checking the Feed Clutch for resistance.
Disconnect P/J4201 of the Feed Clutch.
29
Is the resistance across J4201-1 and J4201-2
approximately 280-ohm?
