OBD-II General Scan Tool
HOW TO USE OBD-II GENERAL SCAN TOOL1. 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 the data link connector located in the lower portion of the instrument panel (on the driver's side).
3. Using the OBD-II general scan tool, call up diagnostic trouble code(s) and freeze frame data. OBD-II general scan tool functions consist of:
1. MODE $01; Current power train diagnostic data
2. MODE $02: Power train freeze frame data
3. MODE $03: Emission-related power train diagnostic trouble code
4. MODE $04: Clear/reset emission-related diagnostic information
Read out data according to repair procedures. (For detailed operation procedures, refer to the OBD-II General Scan Tool Instruction Manual.)
NOTE: For details concerning diagnostic trouble codes (DTCs), refer to the List of Diagnostic Trouble Codes (DTC).
MODE $01 (CURRENT POWER TRAIN DIAGNOSTIC DATA)
Refers to data denoting the current operating condition of analog input/output, digital input/output and/or the power train system.

MODE $02 (POWER TRAIN FREEZE FRAME DATA)
Refers to data denoting the operating condition when trouble is sensed by the on-board diagnosis system.
PID 02 - 0D:
A list of support data and PID (Parameter Identification) codes are shown in the table.
MODE $03 (EMISSION-RELATED POWER TRAIN DIAGNOSTIC TROUBLE CODE)
Refer to Read Diagnostic Trouble Code for information about data denoting emission-related power train diagnostic trouble codes
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 clear or reset emission-related diagnostic information (MODE $04)
