•

Do not drop or subject the SRS-ECU to impact or vibration. If denting, cracking, deforma-
tion, or rust are discovered in the SRS-ECU, replace it with a new SRS-ECU.

•

After deployment of an air bag, replace the SRS-ECU with a new one.

•

Never use an ohmmeter on or near the SRS-ECU, and use only the special test equipment 
described here
