If Honda Civic Gen 7 SRS light has been on for a while, Pull the code to be sure. Here’s how to do it.
All credit goes to user R3dline on ClubRSX).
How it do: (READ THE ENTIRE THING BEFORE PERFORMING. It’ll help. I promise)
1) With the engine/car off and key out of ignition, jump pins 4 & 9 on the OBD connector with a paperclip, length of wire with the ends stripped, etc.
2) Turn your key to the “on” position. Don’t start it, but just turn it on.
3) Your SRS light is gonna blink. Pay attention to the pattern! Luckily, the SRS light illuminates for 6s (bulb check), shuts off for 3s, then it starts the main code. After the main code, you get a 2s break to relax your eyes, then the sub-code. I’m not 100% sure on what happens after the 3s pause after the sub code, but it likely goes straight into the main code again.
The first set of blinks (after the bulb check) is gonna be the main code. Could either be slow blinks (1.2s between blinks) or super fast blinks (0.1s between blinks)
Count each slow blink as 1
Count each set of 4 super fast blinks as 10
Add them all together, and you get the main code
Second set of blinks is gonna be the main code. Remember, you get a 2s break to compose yourself. lol.
These are gonna be about 4x as fast as the slow blinks from the main code (0.3s between blinks)
Count each blink as 1
Add them together for the sub-code.
After you do all that, you should end up with a [main code]-[sub code] pairing. Match it to the list below, fix whatever issue instead of spray and pray with the parts cannon.
Hope this helps your troubleshooting.
However, if you can’t troubleshoot in the above method.
The easier way is to have one HDS HIM Diagnostic Tool
