Description of On-Board Diagnostics

The self-diagnostic function of the SRS system allows it to locate the causes of system problems and to store this information in memory. For easier troubleshooting, this data can be retrieved via the data link circuit.
- When you turn the ignition switch ON (II), the SRS indicator will come on. If it goes off after six seconds, the system is normal.
- If there is an abnormality, the system locates and defines the problem, and stores this information in memory while the SRS indicator light turns on.

NOTE: The data will remain in the memory even when the ignition switch is turned off, or if the battery is disconnected.

- When you connect the SCS service connector to the service check connector (2-P), and turn the ignition switch ON (II), the SRS indicator light will indicate the diagnostic trouble code (DTC) by the number of blinks.
