'03 Impala Airbag light is on and getting 7 blinks at key on before going
I'm getting codes B0022, 26, 42, 43 and 44. All are driver side (LF) deploy
failure codes related to open loops or voltage problems.
Could this be all from a bad clockspring ? My appliance tech gut says yes
but it's my brothers car and since I'm the family wrench I get the first
whack at the problems.
Pro techs thanks in advance......
You need to check the resistances between the sirs module and the clock
spring coil connector then the resistances from the connector to the air bag
connector itself to be sure of any diagnosis, there are listed specs for
this in the shop manual.
20 series codes are for stage 1, 40 series codes for stage 2.
22 and 42 are internal short.
43 is short to ground or short to volts and low resistance
26 and 44 are for an open
Stage 1 wires are tan (high) and brown, stage 2 are white (high) and pink.
I don't have resistance specs, it just says "test'
With that many codes, check for a damaged harness, crushed or a screw
through it or something, usually you get 1 or 2 codes. There's only 1 code
for the steering wheel deployment module that you don't have.
