DISABLE PROCEDURE AND TIME (Always Check Service Manual)

Before using an electric welder on the vehicle, remove any SRS parts around the area being repaired

1. Turn ignition switch to OFF and remove key.
2. Disconnect and isolate negative battery cable.
3. Wait at least 90 seconds.

When the cable is disconnected from the negative (-) battery terminal, the memory settings of each system will be cleared. Because of this, be sure to write down the settings of each system before starting work. When work is finished, reset the settings of each system as before. Never use a backup power supply from outside the vehicle to avoid erasing the memory in a system
