Import Enhanced (OBD II) Diagnostics

Read Codes

The Read Codes function retrieves Diagnostic Trouble Codes (DTCs) from the vehicle’s computer module(s). This function can be performed with the KOEO or KOER. These codes cause the computer to illuminate the Malfunction Indicator Lamp (MIL) when an emission-related or driveability fault occurs. The MIL is also known as the “service engine soon” or “check engine” lamp.

Not all Import vehicles support DTC status. For a description of these screens, refer to the Global OBDII section of the manual.

•History Codes — codes placed in the vehicle’s memory when the trouble originally occurred, and will remain there even if the trouble has been cor- rected. If no trouble after 50 engine warm-up cycles, the DTC will be erased.

•Current Codes — codes transmitted through the PCM’s data stream when a trouble condition is active and cannot be erased. The problem must be repaired to remove the DTC.
