Often a poorly maintained base system will cause significant problems in the electronic control systems. Low engine vacuum can point to
mechanical problems in the engine. Poor cooling system performance will affect the computer controls on the engine.
QT = Quick Test DT = Diagnostic Testing
FUEL SYSTEM
Long term fuel trim will point you to possible mechanical fuel
system problems causing the computer to compensate by adjusting
fuel delivery. Unequal fuel distribution can cost up to six percent in
fuel economy before tripping the check engine light.
QT - Fuel trim specification
DT - Fuel pressure
DT - Fuel volume
DT - Perform injector balance test
IGNITION SYSTEM
Inadequate primary system voltage will always lead to poor
performance. A secondary ignition misfire can cause up to a five
percent loss in fuel economy.
QT - Secondary circuit voltage
DT - Primary circuit voltage
DT - Primary circuit current draw
DT - Base timing at idle
DT - Knock sensor operation
EMISSION SYSTEM
Worn or lazy oxygen sensors can cost your customer up to
six percent fuel economy! The emissions systems check can be
performed on your inspection machine at the same time as the
exhaust gas analysis.
QT - Oxygen sensor operation
DT - EGR system operation
DT - PCV system operation
DT - EVAP system operation
DT - Catalytic converter efficiency
DT - Perform exhaust gas analysis
POWERTRAIN CONTROL
Computer recalibration may correct what seems to be a mechanical
problem and is often called for in technical service bulletins. Using
the history codes and readiness monitors will help you determine
overall powertrain conditions.
QT - Computer recalibration updates
QT - Diagnostic trouble codes
QT - History codes
QT - Snap shot data
QT - OBD II readiness monitors
QT - Scan tool sensor data
DT - Technical service bulletins
THE 21ST CENTURY TUNE-UP
initially consists of a
customer interview and a series of 18 quick test vehicle inspections,
followed by diagnostic testing as needed. The customer interview
gives you the opportunity to find out how the customer feels
about the vehicles performance, how the vehicle is treated and a
sense of the vehicles history. The Quick Test (QT) vehicle
inspections are designed to be completed in about 30 minutes.
CUSTOMER INTERVIEW
Have you noticed poor performance?
Are you planning a long vacation trip?
Are you aware of any specific problem?
When and how does the problem occur?
How confident are you in your vehicle?
Has the check engine light ever been on?
What services have been done recently?
When was your last emissions inspection?
Have the fuel injectors ever been cleaned?
Have the oxygen sensors ever been replaced?
The vehicle owner is concerned with the reliability of the
vehicle. He may have a wife and small children or they may be
older couples who want to minimize the chance of a breakdown
occurring. Whether preparing for a change of seasons, a vacation
or handing the car down to a child, investing a reasonable cost to
ensure family safety is easily accepted by the vehicle owner.
After the interview, the quick test inspections will give you an
accurate report on the vehicle health, pointing to systems that
need further diagnostic tests and allowing you to explain all
options to your customer.
The 21st Century Tune-Up program will:
Improve reliability
Reduce air pollution
Improve performance
Improve fuel economy
Create customer confidence
