- •Internal module failure (rarer)
Symptoms you'll see
- •SRS light steady
- •B1004 active fault
- •Inflators don't activate
The fix path
Ship the SRS module — we test on the bench. If it's crash data, $75 clear. If it's hardware failure, we report back so you can source a working donor.
AML services that fix this
Mail in the affected module, we bench-program, ship back next business day. Flat pricing, return shipping included.
