Hope someone out there can save me a costly trip to the dealer!

I bought a crashed 2004 TL A-Spec. Airbags, sensors and control module were replaced. Tried to clear codes, but no luck, so now I am getting three codes from the SRS light in the dash:

3-1
3-2
8-5

I am not sure, but I think the first two refer to the left side seatbelt pretentioners, which makes sense because I have not replaced the seat belts yet, but can anyone confirm?

Finally, that last one really confuses me. According to some code manuals I've seen around the internet, 8-5 means "8-5 Internal Failure of the SRS unit". What does that mean?!? And how do you fix it?!?!

Thanks in advance for any help you can offer!

 

NOTE: Before doing any SRS repairs, use the HDS SRS Menu Method to check for DTCs; refer to the DTC Troubleshooting Index for the less obvious deployed parts (seat belt tensioners, front impact sensors, side impact sensors, etc.).

After a collision where the seat belt tensioners deployed, replace these items:

SRS unit

Seat belt tensioners

Front impact sensors

After a collision where the front airbag(s) deployed, replace these items:

SRS unit

Deployed airbag(s)

Seat belt tensioners

Front impact sensors

After a collision where the side airbag(s) deployed, replace these items:

SRS unit

Deployed side airbag(s)

Side impact sensor(s) (first) for the side(s) that deployed

After a collision where the side curtain airbag(s) deployed, replace these items:

SRS unit

Deployed side curtain airbag(s)

Side impact sensor(s) (first) for the side(s) that deployed

Side impact sensor(s) (second) for the side(s) that deployed

Roof trim

B-pillar upper trim

Front grab handle

Any related trim clips

Replace the clips on these parts even if they look undamaged:

A-pillar trim

B-pillar trim

C-pillar trim

Front grab handle

Sunvisor

After a moderate to severe side or rear collision, inspect for any damage on the side curtain airbag or other related components. According to the degree of damage, replace components as needed.

After a collision, where a side curtain airbag has deployed, replace all trim clips on that side, even if they appear to be undamaged.
