2.3.2 Read Codes
The Read Codes function retrieves Diagnostic Trouble Codes (DTCs) from vehicles
computer modules. This function can be
performed with the key on and the engine off or
the key on and engine running.
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.
Select Read Codes and press ENTER. The scan tool retrieves the DTCs stored in the
vehicles computer module(s).
The scan tool displays the DTCs or a message
stating SYSTEM PASS: NO CODES FOUND.
Press the DOWN arrow key to view the DTCs or
press the BACK key to return to the OBDII
Function List.
Write down the DTCs for reference, then press BACK to return to the OBDII Function List.
2.3.3 Pending Codes
Pending Codes are also referred as continuous monitor and maturing codes. An
intermittent fault causes computer to store a code in memory. If fault does not occur
again within 40 warm-up cycles, the code clears
from memory. If the fault occurs a specific number
of times, the code matures into a DTC MIL
illuminates or blinks. This function can be per-
formed with the key on and engine running or
not.
