CAUTION:
All SRS electrical wiring harnesses are covered with
yellow outer insulation.
Before disconnecting the SRS wire harness, Install
the short connector on the airbus (see page 23-323).
Raplace the entire affected SRS harness assembly
if it has an open circuit or damaged wiring.
After installation of the gauge assembly, recheck the
operation of the SRS indicator light.
Remove the gauge assembly from the dashboard and dis-
connect the 30-P connector from the gauge assembly.
Make the following input tests at the connector termi-
nals. If all tests prove OK, yet the indicator still fails to
work, replace the main printed circuit panel, speedome-
ter, tachometer and odo/trip meter.
