Diagnostic Service Procedure
It is very important that the proper General Motors
Service Procedure be followed to produce reliable
test results. Depending on the circumstances, the
user may need to reference one or more of the
following procedures:
- Fuel Composition Diagnosis
- Alcohol/Contaminants-in-Fuel Diagnosis
- Fuel System Cleaning
- Fuel Composition Sensor Test
- P0169 - Incorrect Fuel Composition
- P0178 - Fuel Composition Sensor Circuit
Low Frequency
- P0179 - Fuel Composition Sensor Circuit
High Frequency

End of Test Procedure

When the test is complete, disconnect the DMM
from the Fuel Composition Tester by removing the
DMM test leads from the tip jacks at the base of
the tester handle. The fuel sample can be discarded
by picking up the tester by the handle and pouring
the sample out of one side of the funnel (see
figure 10). Fuel should be disposed of in accordance
with all applicable federal, state and local
requirements.
In order to prevent contamination of the sensing
cell it is recommended that the tester be allowed
to air dry with the tester upside-down for at least
five minutes. DO NOT USE compressed "shop air"
to blow out the tester. Compressed shop air often
contains water or solid contaminants that could
leave the tester's sensing cell "dirty". Simply turn
the tester upside down on a flat surface, such as
a metal workbench. The tester has been designed
to allow fluid to exit the tester in this position, and
