OBD-II General Scan Tool

OPERATION

1. HOW TO USE OBD-II GENERAL SCAN TOOL

1. Prepare a general scan tool (OBD-II general scan tool) required by SAE J1978.




2. Open the cover and connect the OBD-II general scan tool to data link connector located in the lower portion of instrument panel (on the driver's side).
3. Using the OBD-II general scan tool, call up DTC and freeze frame data.
OBD-II general scan tool functions consist of:
1. MODE $01: Current powertrain diagnostic data
2. MODE $02: Powertrain freeze frame data
3. MODE $03: Emission-related powertrain DTC
4. MODE $04: Clear/Reset emission-related diagnostic information
5. MODE $06: Request on-board monitoring test results for non-continuously monitored systems
6. MODE $07: Request on-board monitoring test results for continuously monitored systems
7. MODE $09: Request vehicle information Read out the data according to repair procedures. (For detailed operation procedures, refer to the OBD-II General Scan Tool Operation Manual.)

NOTE: For details concerning DTC, refer to the List of Diagnostic Trouble Code (DTC).

2. MODE $01 (CURRENT POWERTRAIN DIAGNOSTIC DATA)




Refers to data denoting the current operating condition of analog input/output, digital input/output and/or the powertrain system.
A list of the support data and PID (Parameter Identification) codes are shown in the table.

NOTE: Refer to OBD-II general scan tool manufacturer's instruction manual to access generic OBD-II PIDs ( MODE $01).

3. MODE $02 (POWERTRAIN FREEZE FRAME DATA)




Refers to data denoting the operating condition when trouble is sensed by the on-board diagnosis system.
A list of the support data and PID (Parameter Identification) codes are shown in the table.

NOTE: Refer to OBD-II general scan tool manufacturer's instruction manual to access freeze frame data ( MODE $02).

4. MODE $03 (EMISSION-RELATED POWERTRAIN DIAGNOSTIC TROUBLE CODE (DTC))
Refer to Read Diagnostic Trouble Code (DTC) for information about data denoting emission-related powertrain DTC.

5. MODE $04 (CLEAR/RESET EMISSION-RELATED DIAGNOSTIC INFORMATION)
Refers to the mode used to clear or reset emission-related diagnostic information (OBD-II trouble diagnostic information).

NOTE: Refer to OBD-II general scan tool manufacturer's instruction manual to clearer reset emission-related diagnostic information ( MODE $04).

6. MODE $06




Refer to test value of troubleshooting and data of test limit on support data bit sequence table. List of support data is shown in the table.

7. MODE $07
Refer to data of DTC (pending code) for troubleshooting result about emission in first time.

8. MODE $09
Refer to data of vehicle specification (VIN, calibration ID, etc.).
