OBD-II/EOBD<br />
OBD Health Check<br />
6.1.1 Global OBD II Code Check<br />
Global OBDII Code Check displays stored emissi<strong>on</strong> related generic DTCs reported by the ECM.<br />
Selecting this opti<strong>on</strong> opens a submenu with two choices: Codes and Pending Codes. Selecting<br />
either opti<strong>on</strong> opens a code list.<br />
Figure 6-2 Sample code list<br />
Codes<br />
The Codes opti<strong>on</strong> displays a list of current emissi<strong>on</strong> related DTCs.<br />
OBD-II/EOBD Codes have a priority according to their emissi<strong>on</strong> severity, with higher priority codes<br />
overwriting lower priority codes. The priority of the code determines the illuminati<strong>on</strong> of the MIL and<br />
the code erase procedure. Vehicle manufacturers have implemented the ranking differently, so<br />
there are differences between makes.<br />
Pending Codes<br />
The purpose of this service is to enable the scan tool to obtain “pending” or maturing diagnostic<br />
trouble codes. These are codes whose setting c<strong>on</strong>diti<strong>on</strong>s were met during the last drive cycle, but<br />
need to be met <strong>on</strong> two or more c<strong>on</strong>secutive drive cycles before the DTC actually sets.<br />
Use this service following a vehicle repair and code clearing procedure to verify test results after<br />
a single drive cycle.<br />
• If a test failed during the drive cycle, the DTC associated with that test is reported. If the<br />
pending fault does not occur again within 40 to 80 warm-up cycles, the fault is automatically<br />
cleared from memory.<br />
• Test results reported by this service do not necessarily indicate a faulty comp<strong>on</strong>ent or system.<br />
If test results indicate another failure after additi<strong>on</strong>al driving, then a DTC is set to indicate a<br />
faulty comp<strong>on</strong>ent or system, and the MIL is illuminated.<br />
