5.2 Read Codes
The Read Codes function allows the scan tool to read
the DTCs from the vehicle’s control modules. DTCs are
used to help determine the cause of a problem or prob-
lems with a vehicle. These codes cause the control
module to illuminate the malfunction indicator lamp
(MIL) when emission-related or driveability fault occurs.
When referring to the engine control module, MIL is also
known as service engine soon or check engine lamp.
Read Codes can be done with the key on engine off
(KOEO) or with the key on engine running (KOER).
