The following options are available from the OBD-II/EOBD menu:
• OBD Health Check
• OBD Direct
10.2.1 OBD Health Check
The OBD-II Health Check offers a way to quickly check for and clear emissions-
related diagnostic trouble codes (DTCs), and to check readiness monitors for
emissions testing. Selecting opens a connection message. Select Continue or
press the Y/a button to open a submenu of test options (Figure 10-1).

Global OBD II Code Check
Global OBDII Code Check displays stored emission related generic DTCs reported
by the ECM. Selecting opens a submenu with two choices: Codes and Pending
Codes. Either option opens a code list (Figure 10-2).
The DTC results screen is similar to the same screen used in the Scanner function,
as both display the SureTrack results message below the toolbar. However,
SureTrack is not accessible in OBD-II/EOBD mode. SureTrack is only accessible in
the Scanner function where the vehicle has been identified.

Codes
The Codes option displays a list of current emission related DTCs.
OBD-II/EOBD Codes have a priority according to their emission severity. The
priority of the code determines the illumination of the MIL and the code erase
procedure. Vehicle manufacturers have implemented the ranking differently, so
there are differences between makes.
Pending Codes
The purpose of this service is to enable the diagnostic tool to obtain “pending” or
maturing diagnostic trouble codes. These are codes whose setting conditions were
met during the last drive cycle, but need to be met on two or more consecutive drive
cycles before the DTC actually sets.
Save valuable time by using this service to verify test results after a single
drive cycle following a vehicle repair and code clearing procedure.
