Note:

If multiple codes including code 5 – 1 are indicated, first fault find all codes except 5 – 1, then erase the memory and recheck the code indication. If code 5 – 1 does not reappear, it is not necessary to replace the SRS unit.
When an SRS unit is to be returned in the case of a warranty claim, DO NOT erase the memory. The memory will be retained in the unit.
If an intermittent failure occurs, code 9 – 1 will be indicated. In the case of a continuous problem, there will be no code.
