Safety Warnings

 Always perform automotive testing in a safe environment.  Wear safety eye protection that meets ANSI standards.  Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot

engine parts.

 Operate the vehicle in a well-ventilated work area, for exhaust gases are

poisonous.

 Put the transmission in PARK (for automatic transmission) or NEUTRAL (for

manual transmission) and make sure the parking brake is engaged.

 Put blocks in front of the drive wheels and never leave the vehicle unattended

while testing.

 Be extra cautious when working around the ignition coil, distributor cap, ignition

wires and spark plugs. These components create hazardous voltages when the engine is running.

 Keep a fire extinguisher suitable for gasoline, chemical, and electrical fires nearby.  Do not connect or disconnect any test equipment while the ignition is on or the

engine is running.

 Keep the test equipment dry, clean, free from oil, water or grease. Use a mild

detergent on a clean cloth to clean the outside of the equipment as necessary.

Since the introduction of OBD II and leading up to modern Hybrids and EVs, hardware and software technologies in cars have been advancing at an exponential rate. Updating software may be the only way to fix the following issues:

 Drivability  Fuel Efficiency  Power Loss  Fault Codes  Durability of Mechanical Parts

The Programming and Coding function is used to re-flash the vehicle control modules, which allows you to update the computer software of the vehicle to the latest version, as well as to reprogram adaptive data of certain components after making repairs or replacements.

NOTE

The programming function applies only when the vehicle is connected with a VCMI or J2534 programming device, which serves as a PassThru interface to establish communication with and transfer data to the vehicle’s ECU.

Available programming or coding operations vary by test vehicle. Only the available operations display in the tablet menu.

There are two general types of programming operations: A. Coding – also known as Teach-in Program, or Component Adaptation, is used to

reprogram adaptive data for vehicle control modules after repairs or replacements of vehicle parts.

B. Reprogramming Operations – downloads the latest version of software from the

online server database through Internet access (this procedure is done automatically when the tablet is connected to the Internet, so there is no need to check for software updates yourself), and reprograms the newest version into the vehicle’s ECU.

NOTE

Ensure that the tablet is connected to a stable internet access before applying the ECU programming function, so that the tablet is able to obtain access to the vehicle manufacturer’s server for update service.

Selecting the Programming or Coding function opens a menu of operation options that varies by vehicle make and model. Selecting a menu option either displays a programming interface or opens another menu of additional choices. Follow all screen instructions while performing the programming or coding operations. How and what information is presented on the screen vary by the type of operation being performed.

4.9.1 Coding

Figure 4-27 Sample Coding Screen

The main section of the Coding screen displays a list of vehicle components and the coding information that mainly consists of two parts:

1. All available systems for coding are displayed on the left side, and the coding data

or value on the right side.

2. The bottom of the main section displays the functional buttons that enable you to

manipulate the operation. Check the vehicle condition and the coding information carefully. Use the functional

button to edit Codes for the corresponding components. Tap Send when you finish editing all items. When the operation is completed, an execution status message such as Completed, Finished or Successful, may display.

Tap the ESC button to exit the function.

4.9.2 Reprogramming Operation

Before reprogramming begins:

 It is mandatory that Ultra tablet is connected to stable Wi-Fi network.  Tablet must be connected to VCMI by USB.  Tablet battery must be fully charged during module programming. Connect tablet to

charger if needed.

 Attach battery maintainer to vehicle battery to ensure a steady voltage is

maintained throughout programming. Voltage requirements differ by vehicle manufacturer. Consult vehicle manufacturer recommendations prior to programming a module.

 Do not quit the application during a module reprogramming as the process may fail

and may also result in permanent damage to the module.

Typical reprogramming operations require you to input and validate VIN number first. Tap the input box and enter the correct number. The programming interface then displays.

Figure 4-28 Sample Reprogramming Operation Screen

The main section of the reprogramming interface offers information of the hardware, the current software version and the newest software versions to be programmed into the control units.

A series of on-screen operational instructions will display to guide you through the programming procedure.

Carefully read the on-screen information and follow the instruction to execute the programming procedure.

4.9.3 Re-flash Errors

IMPORATANT

When reprogramming onboard, always make sure the vehicle battery is fully charged and in good working condition. During reprogramming, the operation may fail if voltage falls below the proper operation voltage. Sometimes a failed operation can be recovered, but the failed reprogramming can also ruin the control module. We recommend connecting an external battery maintainer to the vehicle to ensure a steady

voltage is maintained throughout programming. The required voltage differs by vehicle manufacturer. Consult vehicle manufacturer for correct voltage to be maintained.

Occasionally a flash update procedure may not complete properly. Common causes of flash errors include poor cable connections between the tablet, VCMI, and vehicle, the vehicle ignition being switched off before the flash procedure is complete, or low vehicle battery voltage.

If the process quits, recheck all the cable connections to assure good communications and initialize the flash procedure. The programming procedure will automatically repeat if the previous operation does not succeed.

4.10 Generic OBD II Operations

The OBD II/EOBD vehicle diagnosis option offers a quick way to check for DTCs, isolate the cause of an illuminated malfunction indicator lamp (MIL), check monitor status prior to emissions certification testing, verify repairs, and perform other emissions-related services. The OBDII direct access option is also used for testing OBD II/EOBD-compliant vehicles that are not included in the Diagnostics database. Diagnostics toolbar buttons at the top of the screen are available for specific vehicle diagnostics. See Table 4-2 Diagnostics Toolbar Buttons on page 31 for details.

General Procedure

 To access the OBD II/EOBD diagnostics functions

1. Tap the Diagnostics application button in the MaxiSys Job Menu. The Vehicle Menu displays.

2. Tap the EOBD button. There are two options to establish communication with the vehicle.

 Auto Scan – select it to establish communication using each protocol in

order to determine which one the vehicle is using.

 Protocol – select it to open a submenu of various protocols. A

communication protocol is a standardized way of data communication between an ECM and a diagnostic tool. Global OBD may use several different communication protocols.

3. Select a specific protocol if the Protocol option is selected. Wait for the OBD II Diagnostic Menu to appear.

Figure 4-29 Sample OBD II Diagnostic Menu

4. Select a function option to continue.

 DTC & FFD  I/M Readiness  Live Data  O2 Sensor Monitor  On-Board Monitor  Component Test  Vehicle Information  Vehicle Status

NOTE

Support functions may vary by vehicle.

Function Descriptions

This section describes the various functions of each diagnostic option:

DTC & FFD

When this function is selected, the screen displays a list of Stored Codes and Pending Codes. When the Freeze Frame data of certain DTCs are available for viewing, a snowflake button will display on the right side of the DTC item. The Erase Codes function can be applied by tapping the functional button at the bottom of the screen.

Figure 4-30 Sample DTC & FFD Screen

 Stored Codes

Stored codes are emission-related DTCs from the ECM of the vehicle. OBD II/EOBD Codes have a priority according to their emission severity, with higher-priority codes overwriting lower-priority ones. The priority of the code determines the illumination of the Malfunction Indicator Light (MIL) and the codes erase procedure. Manufacturers rank codes differently, so DTCs may vary by vehicle.

 Pending Codes

These are codes whose storing conditions have been met during the last drive cycle, but need to be met on two or more consecutive drive cycles before the DTC stored. The purpose of displaying pending codes is to assist the service technician after a vehicle repair when diagnostic information is cleared, by reporting test results after a single driving cycle.

a) If a test fails during the driving cycle, the DTC associated is reported. If the

pending fault does not occur again within 40 to 80 warm-up cycles, the fault is automatically cleared from memory.

b) Test results reported do not necessarily indicate a faulty component or system.

If test results indicate another failure after additional driving, a DTC is stored to indicate a faulty component or system.

 Freeze Frame

In most cases the stored frame is the last DTC reported. Certain DTCs, those that have a greater impact on vehicle emission, have a higher priority. In these cases, DTC of the highest priority is the one for which the freeze frame records are

retained. Freeze frame data includes a “snapshot” of critical parameter values at the time the DTC is stored.

 Erase Codes

This option is used to clear all emission-related diagnostic data including DTCs, freeze frame data and specific manufacturer-enhanced data from the vehicle ECM. This option resets the I/M Readiness Monitor Status for all vehicle monitors to Not Ready or Not Complete status.

A confirmation screen displays when the clear codes option is selected to prevent accidental loss of data. Select Yes on the confirmation screen to continue, or No to exit.

I/M Readiness

This function is used to check the readiness of the monitoring system. It is an excellent function to use prior to having a vehicle inspected for state emissions compliance. Selecting I/M Readiness opens a submenu with two choices:

 Since DTCs Cleared – displays the status of monitors since the last time the DTCs

are erased.

 This Driving Cycle – displays the status of monitors since the beginning of the

current drive cycle.

Live Data

This function enables the display of real-time PID data from the ECU. Displayed data includes analog and digital input and output, and system status information broadcast in the vehicle data stream.

Live data can be displayed in various modes, see 4.5 Live Data on page 43 for detailed information.

O2 Sensor Monitor

This function allows retrieval and review of recent O2 sensor monitor test results stored on the vehicle’s on-board computer.

The O2 Sensor Monitor test function is not supported by vehicles that communicate using a controller area network (CAN). For O2 Sensor Monitor tests results of CAN-equipped vehicles, refer to On-Board Monitor.

On-Board Monitor

This function allows you to view the results of On-Board Monitor tests. The tests are useful after the service when a vehicle’s control module memory is already erased.

Component Test

This function enables dual-directional control of the ECM so that the diagnostic tool can transmit control commands to operate the vehicle systems. This function is useful in determining how well the ECM responds to a command.

Vehicle Information

This function enables the display of the vehicle identification number (VIN), calibration identification number, calibration verification number (CVN), and other information of the test vehicle.

Vehicle Status

This function checks the current condition of the vehicle, such as the communication protocols of OBD II modules, number of fault codes, and status of the Malfunction Indicator Light (MIL).
