WARNING: This page is about a different car, the 2005 Chevrolet Optra5 and 2005 Chevrolet Optra. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Refer to Sensing and Diagnostic Module Handling Caution
in Cautions and Notices.
IMPORTANT:
If the vehicle interior has been exposed to extensive water intrusion such as water leaks, driving through high water, flooding or other causes, then the sensing and diagnostic module (SDM) and SDM connector may need to be replaced. With the ignition OFF, inspect the area of the SDM, including the carpet. If any significant soaking or evidence of previous soaking is detected, the water must be removed, the water damage repaired, and the SDM and SDM connector must be replaced. Before attempting any of these repairs, the supplemental restraint system (SRS) must be disabled. Refer to Disabling the SIR System .
