S058527
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 powertrain diagnostic data
(2)   MODE $02: Powertrain freeze frame data
(3)   MODE $03: Emission-related powertrain diagnostic trouble codes
(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 Operation Manual.)
NOTE:
For details concerning diagnostic trouble codes, refer to the List of Diagnostic Trouble Code (DTC). <Ref. to EN(SOHC)-80, List of Diagnostic Trouble Code (DTC).>

1. HOW TO USE OBD-II GENERAL SCAN
TOOL
S058527A1601
1)   Prepare a general scan tool (OBD-II general scan tool) required by SAE Л 978.
2)  Connect the OBD-II general scan tool to the data link connector (A) located in the lower portion of the instrument panel (on the driver's side).
