Autel Autolink AL609P OBD2 Code Reader Scan Tool | ABS/SRS Diagnose | Turn off Check Engine Light | All 10 Modes of OBD2 Tests

Autel Autolink AL609P

The Code Reader Scan Tool AutoLink AL609P is built to help you determine why the Malfunction Indicator Light or the ABS warning light is on. Featured with ABS/SRS diagnosis + CAN OBDII, 2.8’’ LCD, built-in DTC lookup library, AL609P offers swift code reading function.

SCAN - 2 Systems

The AutoLink AL609P is a powerful OBDII scan tool that provide basic diagnosis and read and erase codes for four systems: ABS, SRS.

ABS

An anti-lock braking system (ABS) is an automobile safety system that allows the wheels on a motor vehicle to maintain tractive contact with the road surface according to driver inputs while braking, preventing the wheels from locking up (ceasing rotation) and avoiding uncontrolled skidding. It is an automated system that uses the principles of threshold braking and cadence braking which were practiced by skillful drivers with previous generation braking systems. It does this at a much faster rate andwith better control than many drivers could manage

An ABS warning lamp that is on usually means trouble and you need to pull the code to figure out what is wrong. The ML629 provides convenient service to read and erase codes for the ABS.

Read Codes

Erase Codes

1. Select Erase codes from the diagnostic function list
2. Follow the on-screen instruction and make sure the ignition on and engine off.

3. A confirmation message “DTCs and freeze data will be deleted. Are you sure you want to continue?” will pop up to ask for your confirmation.

   

4. Erase Codes command will be sent and you can perform Read Codes function to verify

   

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.
