| ( 5 ) | A long extension wire may also be needed to check the continuity of some wiring harness circuits. |
Note: Due to all the new features of the PL1000E, the PL1000E requires the use of Caterpillar Communication Toolkit or Caterpillar Electronic Technician that is version 2007B or newer.
Troubleshooting Software
The Cat ET Service Tool or Caterpillar Communications Tool Kit is used to connect, configure, and monitor the PL1000E Communication Module. Information related to operation of the Cat ET can be found online at https://productsupportglobalcontent.cat.com. The PL1000E Communication Module requires version 2007B or later of the Cat ET and version 2007B or later of the Caterpillar Communications Tool Kit.
The Caterpillar Communications Tool Kit provides customer level access to information on the data link. Table 2 lists and compares the information access capabilities of these two service tools.
| Service Tool Capability | ||
| Service Tool Feature | Caterpillar Electronic Technician | Caterpillar Communication Tool Kit |
| PL1000E ECM Summary | Yes | Yes |
| PL1000E ECM Configuration | Yes | Yes |
| PL1000E ECM Status | Yes | Yes |
| PL1000E ECM Totals | Yes | Yes |
| All other ECM Summary | Yes | Yes |
| All other ECM Configuration | Yes | No |
| All other ECM Status | Yes | No |
| All other ECM Totals | Yes | No |
| All ECM Events | Yes | No |
| All ECM Diagnostics | Yes | No |
| Flash New ECM Software | Yes | No |
| Perform Calibrations | Yes | No |
When service tool is started, service tool will attempt to identify modules on the target data link. All identified devices are displayed in a selection dialog box by the service tool.
If the Embedded Communication Adapter of the PL1000E is used for the service tool connection, ensure the preference settings in the service tool are correctly set. Refer to Illustrations 1, 2, and 3 for the correct settings.

Select “PL1000E” as shown in Illustration 3 and click the OK button. Cat ET will then display the ECM Summary screen. The ECM Summary screen displays the following PL1000E Communication Module information:
- ECM Serial Number
- Personality Module part number
- Personality Module description
- Personality Module release date
- ECM part number
Refer to the System Operation/Test and Adjust, RENR8091, “Electronic Control Module (ECM) – Configure” for more information.

Communication Gps (1) Personal computer (PC) (2) Custom built PL1000E Communication ECM service cable (optional) (3) 196-0055 Serial Cable (4) 171-4401 Communication Adapter As (5) 207-6845 Adapter Cable As (Data Link) (6) Connects to RS-232 Serial Port 3 of PL1000E Communication ECM |
|
Note: Items (3), (4), and (5) are part of the 171-4400 Communication Adapter Gp .
Use the following procedure to connect Cat ET and the 171-4400 Communication Adapter Gp .
Note: The PL1000E Communication ECM’s embedded communications adapter may also be used for communications with Cat ET. The use of a Communication Adapter Gp is not necessary. In order to use the embedded communications adapter, a custom built service cable (2) must be connected between the RS-232 serial port of the PC and the RS-232 “Serial Port 3” of the PL1000E Communication ECM.
- Turn the engine key switch to the OFF/RESET position. If the key switch is not placed in the OFF/RESET position, then the engine may start.
- Connect cable (3) between the Computer end of communication adapter (4) and the RS-232 serial port of PC (1) .
Note: A 237-7547 Adapter Cable As. is required to adapt the cable (3) to the USB port on computers that are not equipped with a RS-232 serial port.
- Connect cable (5) between the Data Link end of the communication adapter (4) and the service tool connector.
- Turn the engine key switch to the ON position, then start the Cat ET. The Cat ET will initiate communications with the electronic control modules on the engine. The Cat ET will list the available electronic control modules on the engine after communication has been established. If Cat ET and the communication adapter do not communicate with the ECM, refer to Troubleshooting, RENR8091, “Problem – CAT ET unable to detect any electronic control modules”.
Embedded Communications Adapter
The Embedded Communications Adapter (ECA) functionality is always enabled and always available for physical connection on serial port number 3. Cat ET preferences must be modified to identify the ECA as the interface hardware. In order to modify the Cat ET preferences select “Tools/Preferences” from the menu. After the Preferences screen appears, click on the Advanced the button. Select “Embedded Communications Adapter” from the available list of communication adapters. Refer to Systems Operation, RENR8091, “Service Tool”.
