Scan Tool Operating Instructions - AK Automotive Training

Manufacturer Applications
The application will initiate the fault reading process then when codes start, will
activate the wiggle test. Wait while this occurs.
Clear Fault Codes
Do not perform this operation until after the KO EO and KO ER tests have been
performed, as this function will delete any stored codes.
The application will initiate the fault reading process then when codes start, will
activate the clear code routine. Wait whilst this occurs.
2 - Digit Systems with KAM
There are two sets of fault codes in relation to this system. Care should be taken in
selecting the correct vehicle from the application list where the appropriate table of
faults is indicated before selecting the OmiCheck menu.
Enhanced EEC IV systems operate in a similar manner to 3-digit codes with active
fault codes. KAM fault codes wiggle test, KO EO and KO ER. There are no circuit
tests available.
For best results, follow the tests in order: KO EO, continuous test then the KO ER test.
Vehicles fitted with 2.4i and 2.9i engines do not have the KAM feature.
KO ER Test - Key On/Engine Running Self Test
The vehicle is required to be at normal operating temperature before this vehicle
self-test routine will start. The vehicle will wait until the engine is warm.
Active followed by KAM faults will be output when the dynamic test starts. The user
may be requested to press the throttle to greater than 4000rpm. This should be done
promptly otherwise a fault will be reported. It may take up to ten minutes before the
codes are output or the throttle request appears.
The self-test routine then enters the service adjust routine. If a fault has been
reported, the vehicle may not enter into this mode. Do not wait longer than ten
minutes for the service mode to start.
Service mode allows the user to adjust idle speed and check timing values. The
vehicle allows approximately ten minutes for this operation before the test ends.
If the time allowed is inadequate, the KO ER test will need to be restarted from the
beginning. Do not adjust the system after service mode has finished.
