8. General Scan Tool
A: OPERATION
1. HOW TO USE GENERAL SCAN TOOL
1) Prepare a scan tool (general scan tool) required
by SAE J1978.
2) Open the cover and connect the general scan
tool to data link connector located in the lower por-
tion 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 the data according to repair procedures.
(For detailed operation procedure, refer to the gen-
eral scan tool instruction manual.)
NOTE:
For details concerning DTC, refer to “List of Diag-
nostic Trouble Code (DTC)”.
