Optional Remote Electronic Service Tool Connector
The optional electronic service tool connector is installed by the customer or the Original Equipment Manufacturer (OEM).Table 22: Parts for Optional Electronic Service Tool Connector The Electronic Service Tool will operate when the engine is running. The Electronic Service Tool will also operate when the engine is not running, but with the ignition switch in the ON position.Figure 38 - Schematic of Data Link Connections for the Remote Service Tool The Negative Battery Bus Bar circuit on the Remote Electronic Service Tool Connector pin B must be connected directly to the Negative Battery Bus Bar. This circuit must not be connected to the negative battery terminal through any other path.The wires for the CDL and ATA data links should be 143-5018 Cable (Twisted Pair). The wire pair should have a minimum of one twist per 25 mm (1 inch). The length of the wire between the remote electronic service tool and the Customer Connector J3 should not exceed 30 mm (98.4 ft). Refer to "J1939 (CAN) Data Link" for the correct installation procedure for this circuit.ATA Data Link
The electronic control system has a standard data link available. This data link is supported by the American Trucking Association (ATA). The ATA Data Link conforms to SAE J1587 and SAE J1708.Table 23: SAE J1587 Data Link Broadcast Parameters J1939 (CAN) Data Link
The Controller Area Network (CAN) Data Link complies with SAE J1939. This data link is used to communicate engine information to a J1939 receiving device (display module).Table 24: Required Parts for a Single Module. Table 25: Required Parts for Additional Modules. Figure 39 - CAN Data Link Modules The following requirements must be met for installation of modules on the CAN data link:* 153-2707 Cable (Shielded Twisted Pair) must be used for all CAN data link runs.* The total length of the data link run must not exceed 40 m (130 ft).* All splices into the data link require a 133-0970 Receptacle As (Tee).* A 174-3016 Receptacle As (Termination Resistor) must be installed at the end of the data link in order to ensure proper operation. A termination resistor for the CAN data link is included in the Caterpillar supplied wiring harness to the J61 customer connector for current engines. One additional termination resistor must be installed at the end of the data link run. Older engines do not have a factory installed termination resistor in the wiring harness. A termination resistor must be installed on both ends of the data link in order to ensure proper operation.Use the following procedure to connect modules to the CAN data link:Figure 40 - CAN Connection to P3 Connector Figure 41 - Socket for CAN Data Link 1. Run the CAN data link from the P3 Customer connector to a module. Older engines do not have a factory installed termination resistor in the wiring harness. A termination resistor must be installed on both ends of the data link in order to ensure proper operation. The end of the data link must be within approximately 150 mm (6 inch) of the module. The total length of the data link run must not exceed 40 m (130 ft).a. Run 153-2707 Cable (Shielded Twisted Pair) from the P3 customer connector to the
