FIP1.39 CLUTCH ASSY PH

Step
Possible causes:
CLUTCH ASSY PH (PL5.1.21, PL7.1.20)
HARNESS ASSY TRAY1 (PL5.1.37)
HARNESS ASSY TRAY2 (PL7.1.36)
HARNESS ASSY CHUTE (PL12.1.17)
HVPS/MCU (PL12.1.19)
LVPS (PL12.1.5)
Checking HARNESS ASSY CHUTE for continuity
Disconnect P/J24 from HVPS/MCU.
Is there continuity between
J24-13 and J245-6?
1
J24-12 and J245-7?
J24-5 and J248-1?
J24-4 and J248-2?
Checking HARNESS ASSY TRAY1 and TRAY2 for
continuity.
Remove CLUTCH ASSY PH.
Disconnect P/J245 or P/J248.
Is there continuity between
2
P/J245-8 and P/J242-1?
P/J245-7 and P/J242-2?
P/J248-5 and P/J247-1?
P/J248-4 and P/J247-2?
Checking the resistance of CLUTCH ASSY PH
Is each resistance of the wire wound resistor between
3 P/J242-1 and P/J242-2, and
P/J247-1 and P/J247-2 of CLUTCH ASSY PH, 172
ohm +/-10% (at 20 °C)?
Checking HVPS/MCU for continuity
Disconnect P/J24 and P/J10 from HVPS/MCU.
4 Is there continuity between
J24-12 and J10-1?
J24-4 and J10-1?
