How To Use
Data Link Connector (DLC) Location
The DLC (Data Link Connector or Diagnostic Link Connector) is typically a 16pin connector where diagnostic code readers interface with the vehicle’s onboard computer. The DLC is usually located 12 inches from the center of the instrument panel (dash), under or around the driver’s side for most vehicles. If Data Link Connector is not located under dashboard, a label should be there telling location. For some Asian and European vehicles, the DLC is located behind the ashtray and the ashtray must be removed to access the connector. If the DLC cannot be found, refer to the vehicle’s service manual for the location.

Application Overview
When the code reader boots up, the Home screen opens. This screen shows all applications loaded on the unit. Following applications are preloaded into the code reader:
- Diagnostics: leads to OBDII screens for all 9 generic OBD system tests.
- IM Readiness:option allows to view a snapshot of the operations for the emission system on OBDII/EOBD vehicles.

Select “Diagnosis”, click “OK” to enter the system diagnosis, select the vehicle type, and enter the diagnosis function list.

Select “ERASE CODES” to clear the fault code

NOTE :
- To review I/M Readiness status, make sure that the ignition key is switched to ON with the engine off.
- Not all monitors are supported by all vehicles.
I/M Readiness is a useful function used to check if all monitors are OK or N/A. The vehicle’s computer performs tests on the emission system during normal driving conditions. After a specific amount of drive time (each monitor has specific driving conditions and time required), the computer’s monitors decide if the vehicles emission system is working correctly. When the monitor’s status is:
- OK – vehicle was driven enough to complete the monitor.
- INC (Incomplete) – vehicle was not driven enough to complete the monitor.
- N/A (Not Applicable) – vehicle does not support that monitor. There are two types of I/M Readiness tests:
- Since DTCs Cleared – shows status of the monitors since the DTCs were last cleared.
- This Drive Cycle – shows status of monitors since the start of the current drive cycle. Below is a list of abbreviations and names of OBD II monitors supported by the code reader.
There are two ways to retrieve I/M Readiness Status data:
One-click I/M readiness key
Typical way: select I/M Readiness from Diagnostic Menu

Freeze Frame menu displays freeze frame data, a snapshot of critical vehicle operating conditions automatically recorded by the on-board computer at the time of the DTC set. It is a good function to help determine what caused the fault.
Select “O2 SENSOR TEST” and click “OK” to view O2 Sensor data Stream.

OBD II regulations require certain vehicles monitor and test oxygen (O2) sensors to isolate fuel and emissions related faults. The O2 Monitor Test function is used to retrieve completed O2 sensors monitor test results.
The O2 Monitor Test is not an on-demand test. O2 sensors are not tested when selected via the menu but tested when engine operating conditions are within specified limits.
1.7 Select “ON-BOARD MONITORING” and click “OK” to view On-Board Monitor data streams.

The On-Board Monitor Test function is useful after servicing or after clearing a vehicle ECU’s memory. It receives test results for emission-related powertrain components and systems that are not continuously monitored for Non-CAN vehicles. And for CAN vehicles, it receives test data for emission-related powertrain components and systems that are and are not continuously monitored. It is vehicle manufacturer who is responsible for assigning test and component IDs.
1Select “EVAP SYSTEM” and click “OK” to view EVAP data streams.

Note: Some manufacturers do not allow tools to control vehicle systems. The manufacturer sets the criteria to automatically stop test. Refer to appropriate vehicle service manual before using this function.
Select” I/M READINESS” and click “OK” to view the I/M data flow.

To retrieve I/M Readiness Status data by one-click I/M readiness key: 1. Press the One-Click I/M Readiness Key on the keypad and the following screen displays. Figure 4-30 Sample Diagnostic Menu Screen 2. Colored LED and build-in beeper provide both visual and audible reminders for emission check and DTCs. Below is the intepretation of the LED and build-in beeper. When the LED is :
- Green – Indicates that engine systems are “OK” and working properply (the number of Monitors equipped with the vehicle which have run and performed their self-diagnostic testing is in the allowed range. MIL is off. ).No stored and pending DTCs exist. The vehicle is ready for an Emissions Test.
- Yellow – The tool finds a possible problem. It indicates the following two conditions: (1) Pending DTCs exist. Please check the I/M Readiness test result screen and use the Read Codes function to view detailed codes information. (2) Some of the vehicle’s emission monitors have not working properly. If the I/M Readiness screen shows no DTC (including pending DTC), but the Yellow LED is still illuminated, it indicate a “Monitor Has Not Run” status.
- Red – Indicates some problems exist with one or more of the vehicle’s system, and the vehicle is not ready for an Emissions Test. As well there are DTCs found. The MIL lamp on the vehicle’s instrument panel will light steady. The problem that is causing the illumination of Red LED should be fixed before an Emissions Test or driving the vehicle further. The built-in beeper works with the colored LED simultaneous, as an assistance to reflect the I/M Readiness test results:
- Green – two long beeps.
- Yellow – short, long, short beeps
Select “REVIEW” and click “OK” to enter the REVIEW DATA list. Select “Review DTC” and Next “OK” to View diagnostic records and delete records.

Select “DTC LOOKUP” and click “OK” to query fault code analysis.

Diagnostic Trouble Codes (DTCs)
OBDII Diagnostic Trouble Codes are codes that are stored by the on-board computer diagnostic system in response to a problem found in the vehicle. These codes identify a particular problem area and is intended to provide you with a guide as to where a fault might be occurring within a vehicle. OBDII Diagnostic Trouble Codes consist of a fi vedigit alphanumeric code. The first character, a letter, identifi es which control system sets the code. The second character, a number, 0-3; other three characters, a hex character, 0-9 or A-F provide additional information on where the DTC originated and the operating conditions that caused it to set. Here below is an example to illustrate the structure of the digits:
