General Scan Tool

General Scan Tool

OPERATION

1. HOW TO USE GENERAL SCAN TOOL
1. Prepare a general scan tool required by SAE J1978.




2. Open the cover and connect the 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 general scan tool, call up DTC and freeze frame data.
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 Read out data according to repair procedures. (For detailed operation procedures, refer to the general scan tool instruction manual.)

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

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.

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.

4. MODE $03 (EMISSION-RELATED POWERTRAIN DTC)
Refer to "List of Diagnostic Trouble Code (DTC)" for information about data denoting emission-related powertrain DTC. Basic Descriptions

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 general scan tool manufacturer's instruction manual to clear or 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 the data of DTC (pending code) for troubleshooting result about emission in first time.

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