INDICATOR
A self-diagnostic circuit is built into the SRS unit; when the ignition switch is turned ON (II), the SRS indicator comes
on and goes off after about 6 seconds if the system is operating normally.
If the indicator does not come on, or does not go off after 6 seconds, or if it comes on while driving, it indicates an
abnormality in the system. The system must be inspected and repaired as soon as possible.
For better serviceability, the SRS unit memory stores a DTC that relates to the cause of the malfunction, and the unit is
connected to the data link connector (DLC). This information can be read with the HDS when it is connected to the DLC
(16P) (see page 24-27).
NOTE: Before you disconnect the negative cable from the battery for troubleshooting, make sure you have the anti-
theft code for the audio system and the navigation system (if equipped). Write down the XM audio presets (if
equipped).
