1
Continuity of the HARNESS ASSY CHUTE
1. Disconnect P/J24 on the HVPS/MCU.
2. Check continuity of the following wiring:
(Refer to
“Connectors
(p.406)”
)
J24-13
↔
J245-6
J24-12
↔
J245-7
J24-5
↔
J248-1
J24-4
↔
J248-2
♦
Does each wiring between J24
↔
J245 and between
J24
↔
J248 have continuity?
Go to Step 2
Replace the
HARNESS
ASSY CHUTE
2
Continuity of HARNESS ASSY TRAY1 and TRAY2
1.
Remove the CLUTCH ASSY PH.
(p.318)
2. Disconnect P/J245 or P/J248.
3. Check continuity of the following wiring:
P/J245-8
↔
P/J242-1
P/J245-7
↔
P/J242-2
P/J248-5
↔
P/J247-1
P/J248-4
↔
P/J247-2
♦
Does each wiring between J245
↔
J242 and between
J248
↔
J247 have continuity?
Go to Step 3
Replace the
HARNESS
ASSY TRAY1
or TRAY2
3
CLUTCH ASSY PH
1. Measure the resistance between P/J242-1
↔
P/J242-
2 and between P/J247-1
↔
P/J247-2.
♦
Is the coil resistance of the CLUTCH ASSY PH
172
Ω
±
10% (20
°
C)?
Go to Step 4
Replace the
CLUTCH
ASSY PH
4
Continuity of the HVPS/MCU
1. Disconnect P/J24 and P/J10 on the HVPS/MCU.
2. Check continuity between the following terminals:
J24-12
↔
J10-1
J24-4
↔
J10-1
♦
Is there continuity between J24
↔
J10?
Go to
3.4.1
LVPS
(p.111)
Replace the
HVPS/MCU
