3. This test checks for proper contact and/or corrosion
of the yellow 2±pin connector at the base of the
steering column.
4. This test isolates the malfunction to one side of the
SRS coil assembly yellow 2±pin connector located
at the base of steering column.

assembly.
Diagnostic Aids:
An intermittent condition is likely to be caused by a poor
connection at the driver air bag assembly harness 2±pin
connector terminals ª1º and ª2º at the top of the steering
column, SRS coil assembly harness 2±pin connection
terminals ª1º and ª2º, SDM terminals ª3º and ª4º, or an
open in CKTs IB05±YEL and IB06±YEL/BLK.
