Figure 2-2 Sample Main Screen Vehicle Coverage The MaxiLink ML629 OBDII/EOBD Scanner is specially designed to work with all OBD II compliant vehicles, including those equipped with Control Area Network (CAN). The EPA requires all domestic, Asian and European vehicles, 1996 and newer (including light trucks), sold in the United States must be OBD II compliant. A small number of 1994 and 1995 model year gasoline vehicles are OBD II compliant.
Toyota, Vauxhall, Volvo, VW, Renault, Peugeot, Lancia, Fiat, Dacia, Citroen, Alfa, Abarth. More vehicle supports will come out with new updates released. Product Troubleshooting This section describes problems that may be encountered while using the scan tool. Vehicle Linking Error A communication error occurs if the scan tool fails to communicate with the vehicle’s ECU (Engine Control Unit). Perform the following steps to resolve error: Verify that the ignition is ON.
Check if the DLC pins are bent or broken. Clean the DLC pins if necessary. Check vehicle battery to make sure it is still good with at least 8.0 volts. NOTE Avoid electrostatic interference during operation. If a failure occurs due to electrostatic interference, please try to operate again.
Scan The MaxiLink ML629 is a powerful OBDII scan tool that provide basic diagnosis and read and erase codes for four systems: ABS, SRS, engine, and transmission. Before using this scan function, please follow the on-screen instructions for selections from vehicle manufacturer to model year to identify the vehicle being tested. 1. Turn the ignition on but do not start the engine. 2. Locate the 16-pin OBDII diagnostic connector (usually under the dash near the steering column).
Figure 3-2 Sample Vehicle Manufacture Screen 6. Use the UP/DOWN scroll button to select the correct Vehicle Model, Year, and Type step-by-step. The steps may vary by test vehicles. After all the selections are made, a vehicle information summary will pop up for your confirmation, press Yes to continue. The four systems will pop up for you to choose, the name of the system may vary by test vehicles.
Read Codes 1. Select ABS from the system list. The list may vary by test vehicles. Figure 3-3 Sample System List 2. Select Read codes from the diagnostic function list. All the DTCs of the ABS control module are displayed. Press Save to save the data or press ESC to exit without saving.
For some trouble codes, you may press OK button to view detailed information of the trouble codes. When there is a FDD button on the right bottom of the screen, press the button to view the freeze frame data of the specific trouble code. Figure 3-5 Sample ABS Trouble Codes Screen 1 Figure 3-6 Sample ABS Trouble Codes Screen 2 Erase Codes 1. Select Erase codes from the diagnostic function list (Figure 3-4). 2. Follow the on-screen instruction and make sure the ignition on and engine off.

OBDII Diagnostics When more than one vehicle control module is detected by the scan tool, you will be prompted to select the module with retrievable data. The Power train Control Module [PCM] and Transmission Control Module [TCM] are the most commonly scanned modules. CAUTION: Don’t connect or disconnect the scan tool while the ignition is on or the engine running. 1） Turn the ignition off. 2） Locate the vehicle’s 16-pin Data Link Connector (DLC). 3） Plug the tool into the vehicle’s DLC.
7） View a summary of system status (MIL status, DTC counts, Monitor status) on screen. Press ESC button for Diagnostic Menu to come up. Figure 4-1 Sample Diagnostic Menu If more than one module is detected, you will be prompted to select a module before testing. Use the UP/DOWN scroll button to select a module and press the OK button. System Status System Status shows the MIL Status, codes found, and monitors status.
Read Codes The Read Codes function can be performed with the key on engine off (KOEO) or with the key on engine running (KOER). Stored Codes are also known as “hard codes”, which are fault codes, or trouble codes that have been stored in the vehicle computer memory because the faults have reoccurred for more than a specified amount of key-cycles. These codes will cause the control module to illuminate the malfunction indicator light (MIL) when emission-related faults occur.
If no codes are found, a message will display “No (pending) codes are stored in the module!” Wait a moment or press any key to return to previous screen. NOTE Permanent Codes function is available only for vehicles supporting the CAN protocols. 3) View DTCs and their definitions on screen. 4) If more than one DTC is found, use the LEFT/RIGHT scroll button to view each code.

Freeze Frame Freeze Frame Data allows the technician to view the vehicle’s operating parameters at the moment a DTC (Diagnostic Trouble Code) is detected. For example, the parameters may include engine speed (RPM), engine coolant temperature (ECT), or vehicle speed sensor (VSS) etc. This information will aid the technician by allowing the parameters to be duplicated for diagnostic and repair purposes.
Retrieving I/M Readiness Status I/M Readiness function is used to check the operations of the Emission System on OBD II compliant vehicles. It is an excellent function to use prior to having a vehicle inspected for state emissions compliance. NOTE Clearing trouble codes also clears the readiness status for the individual emission system readiness tests. In order to reset these monitors, the vehicle must be driven through a complete drive cycle with no trouble codes in memory.
Figure 4-14 Sample I/M Readiness Screen 4) Use the UP/DOWN scroll button to view the status of the MIL light (ON or OFF) and the following monitors: For spark ignition engines: MIS – Misfire Monitor FUEL – Fuel System Monitor CCM – Comprehensive Component Monitor EGR – EGR System Monitor O2S – O2 Sensors Monitor CAT – Catalyst Monitor EVAP – Evaporative System Monitor HTR – O2 Sensor Heater Monitor AIR – Secondary Air Monitor HCAT – Heated Catalyst Monitor For compr
