CAUTION
1. Never attempt to disassemble or repair the SRS-ECU. If faulty, replace it.
2. Do not drop or subject the SRS-ECU to impact or vibration. If dents, cracking, deformation, or rust are discovered on the SRS-ECU, replace it with a new SRS-ECU. Discard the old one.
3. After deployment of the air bags, replace the SRS-ECU with a new one.
