2012 Legacy Airbag Codes
Hello all. I have this Subaru here that I need a little guidance on. This car is an auction car so little is known about it's history. 3 of these codes are referencing the right side circuits or sensors. After gaining access to all three right sensors, I checked all the wiring and connectors and found no faults. These sensors run in series to the module, so all three were replaced with new. Codes remain. Used car dealer provided a used module that changed nothing. I rechecked the wiring, including a pin drag test with the same results. Tried clearing codes with 2 different scanners to no avail. Powers and grounds to main module good.
Regarding the code 29, powers and grounds were good and wiring to main module good. A new ODS module is on order.
Vehicle does look like it was repainted on the right side. Looking for a little direction. My brain is turning to mush.
Make sure the door harness is correct, and none of the wire harness has been repaired. Good Luck!
Thanks Bentley. The door harness looks OE; only two wires to the sensor. No other repairs that I can see.
Hi Ric- you haven't included the actual code numbers in your post, but in looking over the wiring diagrams, I can guess which RH sensors you're referring to. Take a look at "Inspection locations after a collision" in service information. After any airbag activation (safer to assume there was one, than not) the airbag control module is at the top of every one of many large lists of items that
Hi Leo, Those ARE the actual code 'numbers'! AC-EA-EE. ODS module is on order, not the main module. Used car dealer trying to save money got us a used one.
Oops, sorry- you're right. The newer ones are all 4 digit B codes...
I did a double take on them when I first saw them, too.
This system is designed to be diagnosed easily... well, in theory, anyway. If someone melts two communication wires together (e.g., airbag sensor and ODS ones), all bets are off: diag.net/file/f3buwa19u… [this is for a different, but similar, Subaru] This would be fun to diagnose! Also, it is helpful to double-check part numbers of all components -- they may be talking, but
Update: A new SRS main module cleared all of the codes (including the ODS codes) except AC which is for the RF door sensor. Double checked with the dealer and it looks like we were provided with the wrong door sensor as there is a production break for the sedans. I will update again once the correct sensor arrives. Thanks everyone for their input.
Final follow up: After installing the correct door sensor, all codes are gone and the light is off. Thank you to those who replied.
