Neglected Cut Damage through accidental cuts or penetrations will extend in use due to continued flexing and /
or ingress of moisture and road matter.
Impact Fracture Resultant damage from impact fractures is not always visible externally and, therefore, as a safety
precaution the tyre should be removed and examined.
Casing fracture caused by severe localized impact through driving over kerbs, hitting potholes
and / or objects in the road.
A double fracture caused by crushing the side wall of the tyre between an object and the rim
flange.
In both instances, such damage can lead to sudd en and dangerous tyre deflation some time after
the impact occurred.

Leaks
Faults associated with low refrigerant charge weight and low pressure may be caused by leakage. Leaks traced to
mechanical connections may be caused by torque relaxation or joint face contamination. Evidence of oil around such
areas is an indicator of leakage.
Leak Detection
Fluorescent Tracer Dye - A fluorescent tracer dye is incorporated into th e refrigeration system and can be checked for
non-apparent leaks by scanning with a high intensity ultraviolet lamp. The location of leaks can be pinpointed by the bright
yellow glow of the tracer dye.
Automatic Refrigerant Leak Detector - (various manufacturers) Hand-held, portable, battery operated leak detector.
Place in and around A/C system to detect refrigerant leaks.

SAIR System Monitor – Flow Check

When the air pump is energized, the MAF sensor will show a corresponding increase in airflow. The
SAIR pump flow check monitors the MAF sensor signal and two air flow models during normal
secondary air system operation to determine if secondary air is being delivered into the exhaust system.
The SAIR pump flow test compares the actual change in MAF during the pump on and off transitions to
the expected change in airflow from the secondary air fl ow model. (A throttle body flow model is used to
"zero out" errors in the air meter and to compensate fo r transient driving conditions.) The actual airflow is
divided by the expected airflow to calculate an "On flow ratio" and an "Off flow ratio".

A flow ratio that is much less than 1.0 means that the air pump has no/low flow, or the inlet hose to the
pump is disconnected. If secondary air system operation ex tends into closed loop fuel, fuel trim feedback
is used to discriminate between low pump flow and in let hose disconnection. A low flow ratio with a lean
fuel system indicates a disconnected inlet hose. A flow ratio significantly higher than 1.0 (and/or a rich
fuel system indication) indicates that th e outlet hose from the pump is disconnected.

SAIR Diagnostic


The V8 uses the standard FORD non-intrusive monitor that has been adapted for use on a V-engine. The
detection capability is detailed below with the V8 specific modifications highlighted

P0410 - Pump inlet hose disconnection.

P0491 - Low airflow into the exhaust on Bank1. Blocked hose OR failed to open vacuum valve.

P0492 - Low airflow into the exhaust on Bank 2. Blocked hose OR failed to open vacuum
valve.

P2448 - Low airflow into the exhaust on Bank1. Disconnected outlet hose.

P2449 - Low airflow into the exhaust on Bank 2. Disconnected outlet hose.

P0412 - SAIR electrical circuit fault high/low on ecu control pin.

P2257 - SAIR electrical circuit fault high on monitor pin.

P2258 - SAIR electrical circuit fault low on monitor pin.

The determination of which bank is receiving low ai rflow is performed by monitoring the closed loop
fuelling correction supplied from the oxygen sensors. The bank that has the highest enleaning correction is
the bank that has the lowest SAIR flow. If closed loop fuelling is not active when the SAIR pump is
disabled the diagnostic cannot determ ine which bank is receiving low flow and so a fault on both banks is
raised.

The relative difference between the commanded lambda values for each bank is used to determine a
restricted flow to either bank1 or 2 due to a restricted outlet. This enables P0491, P0492 to be raised if the
flow ratio is calculated as in range.

The SAIR functional tests run when SAIR is active and the results are stored until the HEGO monitor has
completed (150-200 seconds after SAIR is off on a typical FTP74). It is only when the HEGO monitor has
completed successfully that any functional SAIR fa ults and SAIR monitor complete is reported.

Comprehensive Component Monitor - Automatic Transmission

General

The MIL is illuminated for all emissions related electrical component malfunctions. For malfunctions
attributable to a mechanical component (such as a clutch, gear, band, valve, etc.), some transmissions are
capable of not commanding the mechanically faile d component and providing the remaining maximum
functionality (functionality is reassessed on each power up). In such case a non-MIL Diagnostic Trouble
Code (DTC) will be stored and, if so equipped, a Transmission Control Indicator Light (TCIL) will flash.
For example on the CD4E transmission, if a gear ratio is not properly obtained and verified due to a
mechanical malfunction, the unobtainable gear is no longer commanded for that power up, the DTC is
stored and the TCIL flashes.
