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.
i Save valuable time by using this service to verify test results after a single drive cycle following a
vehicle repair and code clearing procedure.
• If a test failed during the drive cycle, the DTC associated with that test is reported. If the
pending fault does not occur again within 40 to 80 warm-up cycles, the fault is automatically
cleared from memory.
• Test results reported by this service do not necessarily indicate a faulty component or system.
If test results indicate another failure after additional driving, then a DTC is set to indicate a
faulty component or system, and the MIL is illuminated.
Refer to the Global OBD Vehicle Communication Software Manual for additional information.
Global OBD II Clear Codes
This option is used to clear all emission related diagnostic data, such as DTCs, freeze frame data,
and test results, from the memory of the selected ECM. Although OBD-II/EOBD displays generic
OBD-II/EOBD data only, clearing codes erases all of the stored data, including any enhanced
codes and freeze frame information.
A confirmation screen displays when the clear codes option is selected to prevent accidental loss
of data. Select to continue from the confirmation screen. Refer to the Global OBD Vehicle
Communication Software Manual for additional information.
Readiness Monitors
This test checks the status of the readiness monitoring system. An OBD-II /EOBD control system
runs continuous and periodic tests to check the status of emission-related systems. Two options
are available for Readiness Monitors:
• Monitors Complete Since DTC Cleared—displays the status of all monitors that have run
since the last time ECM memory was erased.
• Monitors Complete This Cycle—displays the status of the monitors that ran during the
current drive cycle only.
