ACTION REQUIRED
Show/hide table
| Harness modification is required with VIMS3G software update identified in Service Magazine, SEPD1668, "New VIMS3G Software Introduction for Cat 793F, 795F and 797F LOHT" and performed per Special Instruction, REHS7388, and REHS7390. Install One CANip harness pn 449-2568-01 per machine as noted in REHS7388 "Rework Procedure for CANip Wiring of VIMS3G on Early Off-Highway Trucks/Tractors". The CANip installation procedure can be preformed independently of the software update. The software update is not required to install the CANip harness. Once the software update is preformed then the CANip installation is required. This is due to the change in module to module communications stragety of the VIMS3G system. Note: The new software is available in the form of a flash file through Caterpillar Service Information System (SIS). Go to SIS Web to make sure that the new flash file part number is still the latest flash file part number. A newer flash file part number may be available. SIS Web only displays the latest available flash file. |
