FIP1.38 CLUTCH REGI
Step Check Yes No
Possible causes:
CLUTCH REGI (PL5.1.23)
HARNESS ASSY CHUTE (PL12.1.17)
HARNESS ASSY TRAY1 (PL5.1.37)
HVPS/MCU (PL12.1.19)
LVPS (PL12.1.5)
1
Checking HARNESS ASSY CHUTE for continuity
Disconnect P/J24 from HVPS/MCU.
Is there continuity between
J24-14 and J245-5?
J24-15 and J245-4?
Go to step 2.
Replace HAR-
NESS ASSY
CHUTE.
2
Checking HARNESS ASSY TRAY1 for continuity
Remove CLUTCH REGI.
Disconnect P/J245.
Is there continuity between
P/J245-9 and P/J243-2?
P/J245-10 and P/J243-1?
Go to step 3.
Replace HAR-
NESS ASSY
TRAY1.
3
Checking the resistance of CLUTCH REGI
Is the resistance of the wire wound resistor between
P/J243-1 and P/J243-2 of CLUTCH REGI, 172 ohm +/-
10% (at 20 °C)?
Go to step 4.
Replace CLUTCH
REGI. (RRP5.6)
4
Checking HVPS/MCU for continuity
Disconnect P/J24 and P/J10 from HVPS/MCU.
Is J24-14 and J10-1?
Go to FIP1.24
LVPS.
Replace HVPS/
MCU. (RRP12.10)
