READ DTC (Diagnostic
Selecting this function allows the Scan Tool to read the Diagnostic Trouble
Codes (DTC's) from the vehicle control modules. DTC's are used to help
quickly determine the cause of a problem or problems within a vehicle. These
codes cause the control module (ECU) to illuminate the Malfunction Indicator
Lamp (MIL) when a fault occurs with one of the monitored systems. MIL is also
known as 'Service Engine Soon' or 'Check Engine' or 'Visit Workshop' lamp.
The ERASE DTC function clears the DTC's and reset all the
I/M Readiness Monitor <<Selection in Document>>Status to a NOT-RUN flashing condition. To set all of
the Monitors to a DONE status, an OBDII Drive Cycle must be performed.
Please refer to the vehicle service manual for information on how to perform
an OBDII Drive Cycle for the vehicle under test. This usually involves
driving the vehicle under certain conditions in order for the ECU's to
'relearn' the driving cycle. Erasing the DTC's from the ECU's memory also
helps with "before and after" diagnostics.
The Live Data function allows Real Time Viewing of the vehicles computer
module PID data. As the computer monitors the vehicle, information is
simultaneously transmitted to the scan tool in real time. In this mode, one can see all
engine parameters in color as engine temperature, advance, engine speed,
throttle position etc. etc. This unit also allows you to Save the live data
readings for later comparison with a similar vehicle! The color coding
changes as the monitored values go higher or lower from a predetermined
range. This helps greatly with finding intermittent or latent problems.
When an emission-related fault has occurred, certain vehicle data is
recorded by the on-board computer. This information is referred to as Freeze
Frame data. FREEZE FRAME is a snapshot of the operating conditions of the
engine and the relevant sensor values at the time when the fault had occurred.
This way you can see what the operating state of the system (say engine) was
when the fault occurred. i.e. engine temp, timing, vehicle speed, RPM,
throttle position, etc. etc.
When the vehicle on board computers detects a problem in their related
systems or components, their self-diagnostic program will assign a fault code (DTC)
and store it in its memory. They also record a Freeze Frame of the
conditions present when the fault was found and set the Malfunction
Indicator Lamp (MIL) alight. Some faults require detection for two trips in
a row before the MIL is turned on. This mode is used to check the status of
the MIL light, whether it had been set on or off in case the MIL on the
dashboard had malfunctioned or tampered with.
The I/M Readiness (Inspection / Maintenance Readiness) function is used to
view a snapshot of the operations on the emission system monitors in OBD II
equipped vehicles. The vehicle ECU constantly monitors it's dependant
systems and if one of them can not complete a full check it might set a DTC.
i.e. the engine temperature should complete a full circle from cold to hot
in order for the relevant I/M to be considered as 'complete'.
LIVE ACTUATIONS (where available
or permitted by the ECUs)
Some ECU's permit you to actuate (switch
On/Off etc. etc.) some of their operating circuits in order to diagnose
functionality of the relevant actuators. i.e relays, fans, door locks,
lights, injectors, A/C clutch etc. etc.
INFORMATION (where available or permitted by the ECUs)
This function allows the Scan Tool to request the vehicle information (VIN),
calibration ID(s) which identifies software version in vehicle control
module(s), and calibration verification numbers (CVN(s), Ignition Key's, etc. etc.
ECU VALUES ADAPTATION /
RESET, KEY and Parts CODING (only where available or permitted
by the ECUs and/or vehicle manufacturer)
Increasingly, some vehicle spare parts come with
'coded' numbers that have to entered in to the ECU in order to recognize
and/or accept the new (or second hand) part. ECU's, Injectors, spare keys,
radios and even starters are now coming out 'coded'. This function is
indispensable if you need to change those vehicle parts.
- Supports most diagnostic protocols including the latest CAN+, VAN,
Read and Erase DTC's, Live data
- Supports large selection of Trucks and Heavy Moving
Vehicles, including the new Chinese made vehicles. (NOTE: this unit is
not for cars)
- Large Color Display with Live + Pass/Fail Sensor Values.
Fully customizable view.
- Can Store up to 4 individual (for a
vehicle model) Good Known Live Values. Plus, it has one manufacturer entry
already for reference. Pass or Fail values are displayed in different colors
which makes pinpointing a troublesome sensor/actuator very easy to pick up.
You can store good Live Data Values from the car's Sensors/Actuators in to
the unit for later reference against the cars you will be fixing!
- This set comes with all the necessary adaptors (more
than 15 in fact) for
different vehicles connection. 12v and 24v operation ensures VAN and Light
Duty vehicles coverage.
- Live HELP for DTC's
and general unit usage. Almost all DTC's have Help screen access with
DTC explanation, troubleshooting and possible remedies. Why, where and
how-to guidance is always at hand!
