8.1 Reading Codes
Reading Codes can be done with the key on engine off (KOEO) or with
the key on engine running (KOER).
Stored Codes are also known as hard codes”or permanent codes”.
These codes cause the control module to illuminate the malfunction
indicator lamp (MIL) when emission-related fault occurs.
Pending Codes are also referred to as“maturing codes or continuous
monitor codes. They indicate problems that the control module has
detected during the current or last driving cycle but are not considered
serious yet. Pending Codes will not turn on the malfunction indicator lamp
(MIL). If the fault does not occur within a certain number of warm-up
cycles, the code clears from memory.
1). Use
UP/DOWN scroll button to select Read Codes from
Diagnostic Menu and press ENTER button.
2). Use
UP/DOWN scroll button to select Stored Codes or Pending
Codes from the Trouble Codes menu and press ENTER button.
