NOTE:

i Only the systems available for testing on the identified vehicle are included in the list.

The identification sequence is now complete.

5.1.1 Alternative V ehicle Identification

Occasionally , you m ay identify a test vehicle th at the Scan ner does not r ecognize, the d at abase
does not support, or has some unique characterist ics that prevent it from co mmunicating with the
Scanner through the normal channels. In these instances, a menu of alternate choices that allow
you to establish communication with the vehicle by other means displays. In add ition to being able
to identify a different manufacturer, the following alternatives are available:

• OBDII/EOBD—allows you to perform generic OBD-II or EOBD tests, see “OBD-II/EOBD“ on

page 35 for additional information.

• System ID Mode—allows you to begin the vehicle identification by first selecting the system

to be tested. Selecting opens a menu of manufacturers that support this mode.

• Select by Database—allows you to begin the vehicle i dentification by fir st selecting which

manufacturer database to load. Selecting ope ns a menu of available databases.

5.2 Connecting to a V ehicle

Make a selection from the systems available for testing list a nd instructions for co nnectin g the
Scanner to the vehicle with the data cable are sh own on the screen ( Figure 5-4).

Figure 5-4 Sample vehicle connection message

If an optional cable adapter is needed, the instruction s te ll you which on e to use, and al so where

Scanner Connecting to a Vehicle

5.2.1 Cables

One of two data cables, one for OBD-II/EOBD compliant vehicles and an optional one for
non-OBD-II/EOBD models, is used to connect the scan tool to the test vehicle. The 26-pin end of
either cable attaches to the dat a cable port on the top o f the scan tool . The con nector is secu red
with captive screws. The 16-pin end of the OBD-II/EOBD cable directly plugs into the data link
connector (DLC) of the test vehicle. With the non-OBD-II/EOBD cable, a cab le adap ter att a ches
to the 15-pin end of the cable and the adapter then plugs into the vehicle test conn ector.

On-screen instructions on the scan tool tell you which cable, and adapter if needed, to use once a
test vehicle has been identified. The screen message also includes the location of the vehicle
diagnostic connector that the cable attaches to for testing the sele cted system.

A replaceable 7.5 amp blade-type fuse is inst alled in the vehicle conne ctor end of the cable to
protect the unit from high circuit voltage and current. A green LED, also on the vehicle connector
end of the cable, illuminates whenever there is power supplied to the cable. An LED that fails to
illuminate indicates either a problem on the vehicle power circuit or a blown data cable fuse.

All OBD-II/EOBD vehicles have vehicle battery power (B+) available on the DLC. The optional
auxiliary power cable supplies power for testing non-OBD-II/EOBD models that do not have B+
available on the diagnostic connector. The optional cable and adapters are required for testing
non-OBD-II/EOBD models.

z To connect the data cable to the vehicle:

1. Follow the on-screen instructions for connecting to the vehicle (Figure 5-4).

2. Once connected, select Continue.
The Scanner establishes communication then displays a list of available tests. If the Scanner

is unable to establish a communications link, a “no communications” message displays.

3. Select from the available tests to open a subme nu of test op tions.

5.2.2 No Communication Message

When the screen displays a “no communication” message , it means the scan tool and the vehicle
control module cannot communicate with each other for some reason.

The following conditions cause a “no communication” message to disp lay:

• The Scanner is unable to establish a communication link with the veh icle.

• You selected a system for testing that the vehicle is not equipped with (such as ABS).

• There is a loose connection.

• There is a blown vehicle fuse.

• There is a wiring fault on the vehicle.

• There is a circuit fault in the data cable or a dapter.

• Incorrect vehicle identification was entered.

Refer to the Vehicle Com municati on Software manuals for manufacturer-specific problems.

Chapter 6 OBD-II/EOBD

This Home screen option allows you to access Generic OBD-II/EOBD Scanner tests without
completing a vehicle identification. This option presents a quick way to check for diagnostic
trouble codes (DTCs), isolate the cause of an illuminated malfunction indicator lamp (MIL), check
monitor status prior to emissions certification testing, verify repairs, and perform a number of other
services that are emissions-related. OBD-II/EOBD is also used for testing OBD-II compliant
vehicles that are not included in the Scanner dat abase s.

OBD-II/EOBD is a Scanner function, and the scan tool must be connected to the test vehicle and
communicating with the display device. Keep in mind, this function pr ovides generic OBD- II
information only. Select from the Vehicle Manufacturers Menu for enh anced OBD-II functions.

Selecting OBD-II/EOBD on the Home screen opens a menu with two options:

• OBD-II Health Check

• OBD-II Diagnose

6.1 OBD Health Check

The OBD-II Health Check offers a way to quickly check for and clear generic diagnostic trouble
codes (DTCs) and to check readiness monitors. Selecting opens a connection message, then a
submenu of test options (Figure 6-1).

Figure 6-1 Sample OBD Health Check menu

35

OBD-II/EOBD OBD Health Check

6.1.1 Global OBD II Code Check

The Code Check displays stored emission related generic DTCs reported by the ECM . Selecting
this option opens a submenu with two choices: Codes and Pending Codes. Select an option to
display the code list.

Figure 6-2 Sample code list

Codes

The Codes option displays a list of current emission related DTCs.
OBD-II/EOBD Codes have a priority according to their emission severity , with higher priority codes

overwriting lower priority codes. 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 scan tool to obt ain “pen ding” o r maturing d iagnostic
trouble codes. These are codes whose setting conditions were met during the last drive cycle, bu t
need to be met on two or more consecutive drive cycles before the DTC a ctually se t s.

The intended use of this service is to assist the service technician following a vehicle re p air and
code clearing procedure by reporting test result s af ter a single drive cycle.

• 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.

• T est results repo rted 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 and the Global OBD Vehicle Communication Soft ware Manual for additional information.

36

OBD-II/EOBD OBD Health Check

6.1.2 Global OBD II Clear Codes

This option is used to clear all emission related diagnostic data, such as DTCs, free ze frame data,
and test results, from the memory of the selected ECM. Although OBD-II/EOBD only displays
generic OBD-II/EOBD data, clearing codes erases all of the stored dat a, 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 Y es on the confirmation screen to continue. Refer to and the Global OBD Vehicle
Communication Software Manual for additiona l information.

6.1.3 Readiness Monitors

Use this menu option to check the readiness of the monitoring system. An OBD-II /EOBD system
checks the status of emission-related subsystems by running continuous or pe riodic tests. Two
viewing options are available once Readiness Monitors is selected:

• Monitors Complete Since DTC Cleared—displays the status of all monitors that have run

since the last time DTC were erased from PCM memory.

• Monitors Complete This Cycle—displays the status of the monitors that ran dur ing the

current drive cycle only.

Select either option and test results are shown in th e dat a viewer (Figure 6-3).

This selection displays a record of any “permanent” codes. A permanent status DTC is one that
was severe enough to illuminate the MIL at some point, but the MIL may no t be on at the present
time. Even though the MIL may have been switched off by clearing codes or because the setting
conditions did not repeat after a specified number of drive cycles, a record of the DTC is reta ined
by the ECM. Permanent status codes automatically clear after repairs have been may and the
related system monitor runs successfully.

6.2.2 Select Communication Protocol

A communication protocol is a standardized way of dat a commun ication b etween an ECM a nd a
scan tool. Global OBD may use the following communication protocols:
