Have a 2008 Tribeca 3.6L Limited, with Airbag light on all the time. Dealer says code 21 for faulty ECU (is what they called it) and wants around $ 875 to replace.
Was wondering
1) If anybody had experience with this issue and resolutions.
2) Where ECU might be located because I cannot find it in Subaru Parts diagrams. (does not list ECU period)
3) Can I get code or not with OBD scanner tool to verify.
Any ideas, suggestions, tips etc....greatly appreciated
Thanks in advance !!!
