System Check - Daewoo MATIZ Service Manual

8B – 10 SUPPLEMENTAL INFLATABLE RESTRAINTS (SIR)
Caution: Use only the scan tool to check the airbag
modules and the sensing and diagnostic module
(SDM). Never measure the resistance of an airbag
module with an ohmmeter. An ohmmeter's battery
can deploy the airbag and cause injury.
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.
Step

Diagnostic System Check
Action
Caution: Do not attempt to repair the supplemental
inflatable restraints (SIR) wiring harness. An SIR re-
pair can create a high-resistance connection which
can keep the airbags from deploying when needed,
resulting in injury.
Circuit Description
When the ignition switch is turned ON, the SDM is able
to send serial data from the terminal 9 of the SDM to the
terminal J (13) of the assembly line diagnostic link.
