Control Module Power - JLG T350 Troubleshooting Manual

A.10 CONTROL MODULE POWER
Always make sure that the ground control module is properly powered.
1. For Ground operation, Pins J001.24, X007.3, and X008.2 should have a voltage of Vbatt. Pin X008.1 should be
grounded.
2. For Platform operation, Pins J001.24, X007.1, X007.2, X008.2, and X060.1 should have a voltage of Vbatt. Pins X008.1
and X060.2 should be grounded.
CAN communication wires should have 60 Ohms resistance between CAN HI and CAN LO whenever connected or 120
Ohms when disconnected. A CAN termination 120 Ohm resistor is located at both ends of the CAN bus. One is in the wire
harness near the platform at X057. The other terminator is embedded in the power module for electric powered machines or
the ground module for engine powered machines. The jumper in the engine powered machine harness between X007.6 and
X007.17 enables the ground module termination resistor.
