 CLUTCH ASSY PH REGI
 HARNESS ASSY R SIDE
 PWBA MCU
Step Check Yes No
1
Check the connection of the CLUTCH ASSY
PH REGI
Check the connection state between CLUTCH
ASSY PH REGI and PWBA MCU.
Are P/J23 and P/J233 connected correctly?
Go to Step [2]. Reconnect P/J23
and P/J233
correctly.
2
Check the continuity of the HARNESS ASSY
R SIDE
Is the continuity between P/J23 <=> P/J233
normal ?
Go to Step [3]. Replace the
HARNESS
ASSY R SIDE.
3
Check the power voltage supply to CLUTCH
ASSY PH REGI
1. Close the interlock switch (HARNESS
ASSY INTERLOCK) before performing
the following work.
2. Measure the voltage between PWBA
MCU ground <=> P/J23-11PIN.
Is the power voltage (approx. +24 V) output?
Replace the
CLUTCH ASSY
PH REGI.
(p.226)
Replace the
PWBA MCU.

 DRIVE ASSY PH
 HARNESS ASSY R SIDE
 PWBA MCU
Step Check Yes No
1
Check the connection of the DRIVE ASSY
PH
Check the connection state between DRIVE
ASSY PH and PWBA MCU.
Are P/J25 and P/J251 connected correctly?
Go to Step [2]. Reconnect P/J25
and P/J251
correctly.
2
Check the continuity of the HARNESS ASSY
R SIDE
Is the continuity between P/J25 <=> P/J251
normal ?
Go to Step [3]. Replace the
HARNESS
ASSY R SIDE.
3
Check the power voltage supply to DRIVE
ASSY PH
1. Close the interlock switch (HARNESS
ASSY INTERLOCK) before performing
the following work.
2. Measure the voltage between PWBA
MCU ground <=> P/J25-1PIN, P/J25-
2PIN.
Is the power voltage (approx. +24 V) output?
Replace the
DRIVE ASSY
PH.
(p.317)
Replace the
PWBA MCU.
