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 problems with a vehicle. These codes cause the

control module to illuminate the malfunction indicator lamp (MIL)

when emission-related or driveability fault occurs. 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).
