DIAGNOSTIC TROUBLE CODE (DTC) 24
IGNITION INPUT CIRCUIT, VOLTAGE TOO LOW
Circuit Description
When the ignition switch is turned ON, the sensing and
diagnostic module (SDM) will perform tests to diagnose
any malfunctions within itself.
After completing the internal tests, the SDM will check
its voltage supply. If the voltage supply is too high or too
low, the SDM may not receive the proper information
when it attempts to use a known current to test the
airbag module circuits.
DTC 24 Will Set When
D The SDM receives the voltage lower than a specified
value.
Test Description
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is discon-
nected. Unintentional deployment of the airbags
can cause injury.
Caution: As a safety precaution, disconnect the con-
nector for the passenger airbag module. Uninten-
tional deployment of the airbags can cause injury.
