16
Checking the connectors of the SENSOR PHOTO (Regi
Sensor) for connection
Check the connections between the PWBA MCU and
SENSOR PHOTO.
Are P/J23 and P/J232 connected correctly?
Go to step 17.
Reconnect the
connector(s) P/
J23 and/or P/J232
correctly.
17
Checking the HARN ASSY L SIDE for continuity
Disconnect J23 from the PWBA MCU.
Disconnect J232 from the SENSOR PHOTO.
Is each cable of J23 <=> J232 continuous?
Go to step 18.
Replace the
HARN ASSY L
SIDE.
18
Checking the power to the SENSOR PHOTO
Disconnect J23 from the PWBA MCU.
Is the voltage across P23-3pin <=> ground on the PWBA
MCU, about +3.3 VDC?
Go to step 19.
Replace the
PWBA MCU.
(Refer to Removal
31/ Replacement
29.)
19
Checking the SENSOR PHOTO for operation
Check the voltage across 23-5pin <=> ground on the PWBA
MCU.
Remove the CHUTE LOW (PL3.2.27) once to check the
operation.
Does the voltage change, when the actuator of the
SENSOR PHOTO is operated?
Replace the
PWBA MCU.
(Refer to Removal
31/ Replacement
29.)
Replace the
SENSOR
PHOTO.
20
Checking the connectors of the CLUTCH ASSY DRV (Regi
Clutch) for connection
Check the connections between the PWBA MCU and
CLUTCH ASSY DRV (Regi Clutch).
Are P/J26 and P/J262 connected correctly?
Go to step 21.
Reconnect the
connector(s) P/
J26 and/or P/J262
correctly.
21
Checking the HARN ASSY KSNR REGCL for continuity
Disconnect J26 from the PWBA MCU.
Disconnect P262 from the CLUTCH ASSY DRV.
Is each cable of J26 <=> P262 continuous?
Go to step 22.
Replace the
HARN ASSY
KSNR REGCL.
22
Checking the power to the CLUTCH ASSY DRV
Disconnect J26 from the PWBA MCU.
Is the voltage across P26-4pin <=> ground on the PWBA
MCU, about +24 VDC when the Interlock Switch (HARN
ASSY INTERLOCK) is pushed?
Go to step 23.
Replace the
PWBA MCU.
(Refer to Removal
31/ Replacement
29.)
23
Checking the CLUTCH ASSY DRV for resistance
Disconnect P/J262 of the CLUTCH ASSY DRV.
Is the resistance across J262-1 and J262-2 approximately
280-ohm?
Replace the
PWBA MCU.
(Refer to Removal
31/ Replacement
29.)
Replace the
CLUTCH ASSY
DRV. (Refer to
Removal 36/
Replacement 24.)
