18
Checking the connectors of the CLUTCH ASSY PH TURN
for connection
Check the connections between the PWBA MCU and
CLUTCH ASSY PH TURN.
Are P/J23 and P/J232 connected surely?
Go to step 19.
Reconnect the
connector(s)
P/J23 and/or
P/J232 surely.
19
Checking the HARN ASSY R SIDE for continuity
Disconnect P/J23 from the PWBA MCU.
Disconnect P/J232 from the CLUTCH ASSY PH TURN.
Is each cable of P/J23 <=> P/J232 continuous?
Go to step 20.
Replace the
HARN ASSY R
SIDE.
20
Checking the power to CLUTCH ASSY PH TURN
Disconnect the connector of P/J23 on the PWBA MCU.
Is the voltage across ground <=> J23-3pin on the PWBA
MCU, about +24 VDC?
Replace the
CLUTCH ASSY
PH TURN.
Replace the
PWBA MCU.
(Refer to Removal
30/ Replacement
14.)
21
Checking the connectors of the DRIVE ASSY PH for con-
nection
Check the connections between the PWBA MCU and
DRIVE ASSY PH.
Are P/J25 and P/J251 connected surely?
Go to step 22.
Reconnect the
connector(s)
P/J25 and/or
P/J251 surely.
22
Checking the HARN ASSY R SIDE for continuity
Disconnect P/J25 from the PWBA MCU.
Disconnect P/J251 from the DRIVE ASSY PH.
Is each cable of P/J25 <=> P/J251 continuous?
Go to step 23.
Replace the
HARN ASSY R
SIDE.
23
Checking the power to DRIVE ASSY PH
Disconnect the connector of P/J25 on the PWBA MCU.
Are the voltages across ground <=> J25-1pin/J25-2pin on
the PWBA MCU, about +24 VDC?
Replace the
DRIVE ASSY PH.
(Refer to Removal
17/ Replacement
27.)
Replace the
PWBA MCU.
(Refer to Removal
30/ Replacement
14.)
24
Checking the connectors of the SENSOR PHOTO (REGI
SENSOR) for connection
Check the connections between the PWBA MCU and
REGI SENSOR.
Are P/J29, P/J292 and P/J2922 connected surely?
Go to step 25.
Reconnect the
connector(s)
P/J29, P/J292
and/or P/J2922
surely.
25
Checking the HARNESS ASSY REGI SNR for continuity
Disconnect P/J2922 from the REGI SENSOR.
Disconnect P/J292 from the HARN ASSY R SIDE.
Is each cable of P/J2922 <=> P/J292 continuous?
Go to step 26.
Replace the HAR-
NESS ASSY
REGI SNR.
26
Checking the HARN ASSY R SIDE for continuity
Disconnect P/J29 from the PWBA MCU.
Disconnect P/J292 from the HARN ASSY REGI SNR.
Is each cable of P/J29 <=> P/J292 continuous?
Go to step 27.
Replace the
HARN ASSY R
SIDE.
27
Checking the power to REGI SENSOR
Disconnect the connector of P/J29 on the PWBA MCU.
Is the voltage across ground <=> J29-8pin on the PWBA
MCU, about +3.3 VDC?
Go to step 28.
Replace the
PWBA MCU.
