After disconnecting the battery cable, wait 60 seco nds or more before proceeding with the
following work. The SRS system is designed to retai n enough voltage to deploy the air bags
for a short time even after the battery has been di sconnected, so serious injury may result
from unintended air bag deployment if work is done on the SRS system immediately after
the battery cables are disconnected. SRS components should not be subjected to heat over
so remove the SRS-ECU,
air bag module and clock spring before drying or ba king the vehicle after painting.
Whenever you finish servicing the SRS, check the SR S warning light operation to make sure that
the system functions properly. (Refer to
Make certain that the ignition switch is OFF when t he scan tool is connected or disconnected.
If you have any questions about the SRS, please con tact the MMSA Tech. Line.
