2. Check the voltage supply to the airbag fuse F31.
Is the voltage within the specified value?

Circuit Description

The airbag indicator will stay on if the sensing and
diagnostic module (SDM) connector is not securely
attached to the SDM. There is a shorting bar in SDM
connector which completes the circuit between the
indicator lamp circuit and ground. The shorting bar is
disengaged when the connector is properly attached.
When the ignition switch is first turned to ON, ignition
voltage applied to the instrument use for the indicator

lamp and also to the airbag fuse for input terminal 5. If
ignition voltage is outside the range of 9 to 16 volts,
the airbag indicator will come on and stay on and
DTC47 will set.

Step

Action

Perform the SRS Diagnostic System Check.
Is the SRS Diagnostic System Check complete?

1. Disable the supplemental restraint system (SRS) in

this section.

2. Replace SDM.
3. Enable the SRS.
4. Make sure all the components are properly mounted.
Is the repair complete?

Circuit Description

When the ignition switch is turned to ON, the sensing
and diagnostic module (SDM) will perform tests to
diagnose critical malfunctions within SDM itself. Internal
fault DTC will set when any of the malfunctions detected
by SDM itself. Refer to “Diagnostic Trouble Code
Table” in this section.

DIAGNOSTIC TROUBLE CODES (DTCS) - INTERNAL FAULT

Action Taken

The SDM will turn on the airbag indicator and set
diagnostic trouble code.

The SDM will shutdown its function partially or totally.

Diagnostic Trouble Code (DTC) - Internal Fault

Caution: The sensing and diagnosis module (SDM)
can maintain sufficient voltage to deploy the airbags
and pretensioners for 0.15 seconds after the ignition
is OFF and the fuse has been removed. If the airbags
or pretensioners are not disconnected, do not begin
s e r v i c e u n t i l o n e m i n u t e h a s p a s s e d a f t e r
disconnecting power to the SDM. Otherwise, injury
could result.

Caution: During service procedure, be very careful
when handling the SDM. Never strike or jar the
SDM. Never power the supplemental restraints
system (SRS) when the SDM is not rigidly attached
to the vehicle. Also SDM mounting nuts must be
carefully tightened to ensure proper operation of
the SRS. The SDM could be activated if it is powered
when it is not rigidly attached to the vehicle,
resulting in unexpected deployment and possible
injury.
