Self-diagnostic System
WARNING: This page is about a different car, the 2013 Honda Fit, 2012 Honda Fit, 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. However, it is still accessible from the selected car via links, so may be relevant.
A self-diagnostic circuit is built into the SRS unit; when the ignition switch is turned to ON (II), the SRS indicator comes on and goes off after about 6 seconds if the system is operating normally. If the indicator does not come on, or if it does not go off after 6 seconds, or if it comes on while driving, it indicates an abnormality in the system. The system must be inspected and repaired as soon as possible.
For better serviceability, the SRS unit memory stores DTCs related to the cause of the malfunction. This information can be read with the HDS when it is connected to the DLC (see READING THE DTC ).
NOTE:
Before you disconnect the negative cable from the battery for troubleshooting, review BATTERY TERMINAL DISCONNECTION AND RECONNECTION
