Retrieving Diagnostic Troble codes1.Connect the Hi-scan Tool to the OBD-II DLC(Data Link Connector). The OBD-II DLC is located under the left side of the instrument panel, near the center conside.
2.Start engine.
3.Refer to the Hi-scan Tool instruction manual and retrieve any DTCs(Diagnostic Trouble Codes).
4.Refer to the Diagnostic Truble Codes, Inspect and repair any applicable condition as instructed.
5.When no further codes are presented, presented, proceed to After Repair Procedure.
After Repair Procedure
1.Cancel the memory of DTC's by disconnecting the negative battery cable at least twenty seconds.
Reconnect the negative battery.
2.Locate the OBD-II DLC(Data Link Connector) and plug the Hi-scan Tool into it.
3.Turn the ignition switch ON.
4.Start and warm engine, by running it at 2,000rpm for three minutes.
5.Verify that no DTC's(diagnostic trouble codes) are recorded.
6.If DTC's are recored, refer to Diagnostic Trouble Codes.
