Best Value for Money - Automotive Diagnostic Code Reader and Live Data Scanner



READ DTC (Diagnostic Trouble Codes)

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 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.

VEHICLE 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 (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.

Key Features:

 -  Supports all diagnostic protocols including the latest CAN+, VAN

 -  Support most car makes today including new Chinese and Malaysian made vehicles

 -  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 available plug-adaptors for diagnosing older vehicle makes!!! About 30 of them are stacked in the briefcase. see picture above.

 -  The CS538D Data Scanner has incorporated Printer for DTC printing.

 -  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!

 -  PC connection via USB/COM for updating the unit. Updates are available via Internet or you can contact us for the latest one.

 -  VGA connector for plugging to a large LCD screen.

 -  NON-Lockable, NON-Expiring software with FREE UPDATES coming almost every month.
