GA ZERO FAILED Purge Flow out of tolerance.
No flow calibration after flow
adjustments
Occlusion during zero calibration.
Solenoid 1 defective.
Measured ambient pressure does not
match with configured altitude in
ACMS Service Mode (tolerance is +/-
60 mmHg).
IR measurement head problem.
Adjust purge flow and calibrate flow.
Repeat zero calibration.
Perform flow calibration
Remove occlusion.
Replace solenoid 1.
Verify correct altitude setting /
pressure Cal value.
If necessary, adjust it.
Check IR head and replace it if
necessary.
