Checking the HARN ASSY R SIDE for continuity
Disconnect P/J281 from the HARN ASSY FDR UNIT.
Disconnect P/J28 from the PWBA MCU.
Is each cable of P/J281 <=> P/J28 continuous?
Go to step 29.
Replace the
HARN ASSY R
SIDE.
29
Checking the power to the PWBA OPT FDR
Disconnect the connector of P/J28 on the PWBA MCU.
Is the voltage across ground <=> J28-4pin/J28-5pin on the
PWBA MCU, about +24 VDC when the interlock switch
(HARN ASSY INTERLOCK) is pushed?
Replace the
PWBA OPT FDR.
Replace the
PWBA MCU.
(Refer to Removal
30/ Replacement
14.)
30
Checking the connectors of the CLUTCH ASSY TURN
OPT for connection
Check the connections between the PWBA OPT FDR and
CLUTCH ASSY TURN OPT.
Are P/J420 and P/J4201 connected surely?
Go to step 31.
Reconnect the
connector(s)
P/J420 and/or P/
J4201 surely.
31
Checking the HARN ASSY C2 TURN for continuity
Disconnect P/J420 from the PWBA OPT FDR.
Disconnect P/J4201 from the CLUTCH ASSY TURN OPT.
Is each cable of P/J420 <=> P/J4201 continuous?
Go to step 32.
Replace the
HARN ASSY
C2 TURN.
32
Checking the power to CLUTCH ASSY TURN OPT
Disconnect the connector of P/J420 on the PWBA OPT
FDR.
Is the voltage across ground <=> J420-1pin on the PWBA
OPT FDR, about +24 VDC when the interlock switch
(HARN ASSY INTERLOCK) is pushed? Replace the
CLUTCH ASSY
PH TURN.
(Refer to Removal
40/ Replacement
4.)
Go to step 33.
33
Checking the connectors of the PWBA OPT FDR and
PWBA MCU for connection
Check the connections between the PWBA OPT FDR and
PWBA MCU.
Are P/J419, P/J281 and P/J28 connected surely?
Go to step 34.
Reconnect the
connector(s)
P/J419, P/J281
and/or
P/J28 surely.
34
Checking the HARN ASSY FDR UNIT for continuity
Disconnect P/J419 from the PWBA OPT FDR.
Disconnect P/J281 from the HARN ASSY R SIDE.
Is each cable of P/J419 <=> P/J281 continuous?
Go to step 35.
Replace the
HARN ASSY FDR
UNIT.
35
Checking the HARN ASSY R SIDE for continuity
Disconnect P/J281 from the HARN ASSY FDR UNIT.
Disconnect P/J28 from the PWBA MCU.
Is each cable of P/J281 <=> P/J28 continuous?
Go to step 36.
Replace the
HARN ASSY R
SIDE.
36
Checking the power to the PWBA OPT FDR
Disconnect the connector of P/J28 on the PWBA MCU.
Is the voltage across ground <=> J28-4pin/J28-5pin on the
PWBA MCU, about +24 VDC when the interlock switch
(HARN ASSY INTERLOCK) is pushed?
Replace the
PWBA OPT FDR.
Replace the
PWBA MCU.
