INSPECT FOR CORRECT VEHICLE INFORMATION AND THE
OPERATIONAL INTEGRITY OF THE ENGINE
Installing an alternative fuel system into a vehicle with an engine or ignition system that is in poor
condition will produce less than desirable results and may lead to exhaust emissions beyond
acceptable levels. It is strongly advised that all of the following inspections be done
BEFORE installing
the Sequent P&D system.
A. Preliminary
Inspection:
The preliminary inspection should consist of a visual inspection of the following items:
•
Emissions Label for correct Model Year, Engine Group, Evaporative Emissions Family and
Engine Type:
o
Model Year: 2009 ONLY
o
Engine Group: 9GMXV03.9052 ONLY
o
Evaporative Emissions Family: 9GMXR0133810 ONLY
Correct MY, Engine Group & Evaporative Emissions Family.
NOTE: If the Emissions label identification information does not match exactly, you
CANNOT install the system in the vehicle. Installation in a non-certified vehicle may be
punishable by a fine and/or imprisonment.
•
Air filter and intake plumbing condition.
•
Engine gaskets and seals for leaks.
•
Exhaust system condition.
•
Cooling system for leaks.
•
Under-hood wiring and hose condition.
•
Inspect the secondary ignition wires, ignition coils and suppressor caps for any signs of
damage or wear.
•
Repair or replace any faulty items.
B. Scan Tool Inspection:
Connect an OBD-II compliant scan tool to the vehicle DLC connector and check the following:
•
Active or Historic fault codes (follow the OEM’s diagnostic recommendations for any codes
found and make necessary repairs).
•
OBD monitors for completion and passed tests.
o
If all applicable monitors have not completed, drive the vehicle until they have completed
and passed.
o
If any monitors have failed a test, follow the OEM’s diagnostic recommendations and
make any necessary repairs.
