- When 2 or more codes are indicated, the code with the lower number appears first.
- If a code is not listed on the display chart, the airbag sensor assy center may have failed.
- In the case of any malfunction concerning an open circuit, short to ground, or short to B+ due to an squib, another malfunction code may not be detected. In this case, repair the malfunction currently indicated and then perform malfunction diagnosis again.
