(5) Perform wirings to the C.Bs. Refer to Fig-5/-6;
• Be sure to connect the wires coming from the
P.W.B. JIG to the same connecting points on the
MAIN C.B as follows.
1) Connect the motor wires and sensor (PD201)
wires that are removed in step (2) to the P.W.B.
JIG.
2) Connect all wires coming from the P.W.B. JIG to
the respective lands of the MAIN C.B by
soldering.
• Connect the motor wires (BLU/WHT) of the
P.W.B. JIG to the motor wire connecting lands on
the MAIN C.B by soldering.
• Connect the LED (LED201) wires (RED/GRY) of
the P.W.B. JIG to the LED wire connecting lands
on the MAIN C.B by soldering.
• Connect the sensor wires (BRN/BLK) of the
P.W.B. JIG to the sensor wire connecting lands on
the MAIN C.B by soldering.
• Connect the sensor (PS201) wires (YEL/ORG/
RED/BRN) of the P.W.B. JIG to the sensor wire
connecting lands on the MAIN C.B by soldering.
• Connect the SW202 wire (WHT) of the P.W.B.
JIG to the SW202 wire connecting lands on the
MAIN C.B by soldering.
• Connect the SW203 wire (BLK) of the P.W.B.
JIG to the SW203 wire connecting lands on the
MAIN C.B by soldering.
• Connect the SW204 wires (BLU/WHT) of the
P.W.B. JIG to the leads of SW204 on the MAIN
C.B by soldering. Refer to Fig-6.
(6) How to use the repair jig;
When the Control Unit (CDC/CT) is going to be used.
1) After all wires and connections are complete,
connect the Control Unit (CDC/CT) with the DIN
jack of the P.W.B. FLEX.
2) Connect external power +12 V to ACC/BACKUP
wire and ground (-) to the GROUND wire.
3) Perform the operation check.
When the Control Unit (CDC/CT) is not used.
1) Connect the supplied P.W.B KEY to the MAIN
C.B by performing all connections between them.
Refer to Fig-7/-8.
(Wires to be used for connecting the MAIN C.B
are not supplied.)
2) Connect the wires as follows. Refer to Fig-9.
