Possible parts that caused the error
CLUTCH ASSY PH TURN
HARNESS ASSY R SIDE
Troubleshooting
Step Check
Check the connection of the CLUTCH ASSY
1
PH TURN
Check the connection state between CLUTCH
ASSY PH TURN and PWBA MCU.
Are P/J23 and P/J234 connected correctly?
Check the continuity of the HARNESS ASSY
2
R SIDE
Is the continuity between P/J23 <=> P/J234
normal?
Check the power voltage supply to CLUTCH

ASSY PH TURN
1. Close the interlock switch (HARNESS
ASSY INTERLOCK) before performing
the following work.
2. Measure the voltage between PWBA
MCU ground <=> P/J23-13PIN.
Is the power voltage (approx. +24 V) output?
