Series 60 DDEC V Troubleshooting – Section 17.2 Connectors

Section 17.2
Connectors

The DDEC V ECM/ECU has two 68-pin Tyco connectors - one for the engine and the other for the vehicle. Each connector has 60 18 AWG terminals and eight 14 AWG terminals (see Figure "ECM/ECU 68-pin Tyco Connector" ).‪

Figure 1. ECM/ECU 68-pin Tyco Connector

The EH 68-pin Tyco connector pinout is listed in Table "Series 60 Engine Harness Connector - Pins E-1 Through E-32" and Table "Series 60 Engine Harness Connector - Pins E-33 Through E-68" .‪

The VIH 68-pin Tyco connector pinout is and Table "Series 60 VIH Connector On-highway Trucks – Pins V-32 – V-68" .‪

The 68-pin connector center screw must be torqued to 50 in·lb (5.6 N·m)‪

The shroud is required to protect the connectors from dirt and direct spray and to route the wires in the correct orientation.‪

If a replacement wire and/or terminal is required, the wires will arrive assembled with the terminals crimped on the wires (see Figure "68 Pin Connector Wires and Terminals" ).‪

Section 17.2.1
Data Link Connector

The SAE J1708/J1587 nine-pin data link connector is required. DDC recommends that the OEM-supplied Data Link Connector be conveniently positioned in a well protected location facilitating subsequent DDDL usage (i.e., reprogramming, diagnostics, etc.).‪

The components listed in Table "Required Components to Incorporate an SAE J1939/J1587 Data Link in the VIH" are required to incorporate a SAE J1939/J1587 Data Link in a VIH for diagnostic and reprogramming devices.‪

The following illustration shows the wiring for the nine-pin connector (see Figure "Wiring for 9-pin Data Link Connector" ).‪

Figure 3. Wiring for 9-pin Data Link Connector

The maximum length for the SAE J1939 Data Link is 130 ft (40 m).‪

The SAE J1587/J1708 Data Link must be twisted pairs. The twists are a minimum of 12 turns per foot (305 mm). The maximum length for the SAE J1587/J1708 Data Link is 130 ft (40 m).‪
