DAEWOO V–121 BL4
spring should never be disassembled, and there is no
timekeeping function. The clock spring contains two or
three current–carrying coils. One of the current–carrying
coils maintains continuous contact within the driver de-
ployment loop while the steering wheel is rotated. The
clock spring also contains coils that maintain continuous
contact for horn and remote audio control switch circuit.
Turning the steering wheel in one direction tightens the
coil, and turning the steering wheel in the opposite direc-
tion loosens the coil. Do not turn the clock spring when the
steering wheel is not attached. Refer to ”Clock Spring” in
this section for proper installation of the clock spring.
The clock spring also includes the wiring and the connec-
tors for the horn circuit and the driver airbag circuit. A yel-
low two–way connector on the lower steering column is at-
tached to the clock spring wiring. The yellow connector to
the airbag contains a shorting bar which connects the driv-
er high circuit to driver low circuit when the connector is
disconnected.
The shorting bar prevents current from travelling through
the driver airbag module during servicing. The shorting bar
is disengaged when the clock spring connector is con-
nected.WIRING HARNESS CONNECTORS
If the sensing and diagnostic module (SDM) electrical con-
nector is not attached properly, a built in shorting bar will
connect the wire from airbag warning lamp with the SDM
ground wire. This turns on the airbag indicator . To prevent
deployment during servicing, additional shorting bars are
located in following locations :
S The clock spring electrical connector at the lower
steering column.
S The passenger airbag module.
S The driver airbag module.
S The seat belt pretensioners.
The shorting bar is only a backup safety device. Always
disable the supplemental inflatable restraints(SIR) before
beginning any service procedure.
