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.

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.
4. Turn the ignition on. Engine can be off or running
5. Turn on the scan tool. Use the SCROLL button to select OBDII/EOBD from the Main Screen
6. Press the OK button and wait for the Menu to appear. A sequence of messages displaying the OBDII protocols will be observed on the display until the vehicle protocol is detected.
7. View a summary of system status (MIL status, DTC counts, Monitor status) on screen
   

System Status

System Status shows the MIL Status, codes found, and monitors status.

Read Codes

• Stored Codes - 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
• Pending Codes - Pending Codes are also referred to as “maturing codes” or “continuous monitor codes”. They indicate problems that the control module has detected during the current or last driving cycle but are not yet considered serious. Pending Codes will not turn on the malfunction indicator lamp (MIL). If the fault does not occur within a certain number of warm-up cycles, the code clears from memory
• Permanent Codes - Permanent Codes are DTCs that are "confirmed" and are retained in the non-volatile memory of the vehicle’s computer until the appropriate monitor for each DTC has determined that the malfunction is no longer present and is not causing the MIL on. Permanent DTCs are stored in non-volatile memory and may not be erased by any diagnostics service or by disconnecting power to ECU.

Erase Codes

Note:

1. Erasing the Diagnostic Trouble Codes may allow the scan tool to delete not only the codes from the vehicle’s on-board computer, but also “Freeze Frame” data and manufacturer-specific enhanced data. Furthermore, the I/M Readiness Monitor Status for all vehicle monitors is reset to Not Ready or Not Complete status. Do not erase the codes before repairs or services have been performed.
2. Even if deleted, codes will again display if the underlining fault causing the code is not addressed.
3. This function is performed with key on engine off (KOEO). Do not start the engine.

Live Data

The View Data function allows viewing of live or real time PID data of vehicle’s computer module(s).

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.

O₂ Monitor Test

OBD II regulations set by the (Society of Automotive Engineers) SAE require vehicles monitors and tests on the oxygen (O₂) sensors to identify problems related to fuel efficiency and vehicle emissions. These tests are done automatically when engine operating conditions are within specified limits. These test results are saved in the vehicle’s on-board computer's memory.

The O₂ Monitor Test function allows retrieval and viewing of O2 sensor monitor test results for the most recently performed tests from the vehicle's on-board computer.

The O₂ Monitor Test function is not supported by vehicles that communicate using a controller area network (CAN). For O₂ Monitor Test results of CAN-equipped vehicles, see chapter “On-Board Mon. Test”.

On-Board Monitor Test

The scan tool allows access to the results of on-board diagnostic monitoring tests for specific components/systems. The vehicle manufacturer is responsible for assigning "Manufacturer Defined Test IDs" and Component IDs for tests of different systems and components. The advanced feature of this scan tool enables you to read the definition of an On-Board Diagnostic Monitor ID.

DTC Lookup

The DTC Lookup function allows user to search definitions of DTC stored in built-in DTC library.

Turn off Check Engine Light(MIL)

AL519 check engine code reader offers complete OBDII diagnostics from pulling DTCs, read live data stream of various sensors, capture freeze frame data to show how the issue happened, to even perform On-Board Monitor Test(Mode 6), O2 Monitor test, and Component Test to check misfire and fuel system to locate bad O2 sensors and figure out the root cause of the Check Engine Light (CEL) and help you turn it off in the most efficient way.
