General Scan Tool

General Scan Tool

OPERATION

1. HOW TO USE GENERAL SCAN TOOL
1. Prepare a scan tool (general scan tool) required by SAE J1978.
2. Connect the general scan tool to data link connector located in the lower portion of the instrument panel (on the driver' side).






3. Using the general scan tool, call up each 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
5. MODE $06: Request on-board monitoring test results for intermittently monitored systems
6. MODE $07: Request on-board monitoring test results for continuously monitored systems
7. MODE $08: Request control for on-board
8. MODE $09: Request vehicle information

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

2. MODE $01 (CURRENT POWERTRAIN DIAGNOSTIC DATA)
Refer to data denoting the current operating condition of analog input/output, digital input/output or the powertrain system.
A list of the support data and PID (Parameter Identification) codes are shown in the following table.






NOTE: Refer to general scan tool manufacturer's operation manual to access current powertrain diagnostic data (MODE $01).

3. MODE $02 (POWERTRAIN FREEZE FRAME DATA)
Refer to data denoting the operating condition when trouble is detected by on-board diagnosis system.
A list of the support data and PID (Parameter Identification) codes are shown in the following table.






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

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

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

NOTE:
- Refer to the manufacturer's operation manual for the general scan tool to clear the emission-related diagnostic information (MODE $04).
- Initial diagnosis of electronic throttle control is performed after memory clearance. Wait for 10 seconds or more after turning the ignition switch to ON, and then start the engine.

6. MODE $06
Refer to diagnostic value of troubleshooting and data of test limit indicated on the support data bit sequence table. A list of the support data is shown in the following table.









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

8. MODE $08 (REQUEST CONTROL FOR ON-BOARD SYSTEM, TEST, AND COMPONENT)
Perform "Active Test" of the on-board system.

9. MODE $09
Refer to the data of vehicle specification (V.I.N., calibration ID, etc.).
