Does anyone have an experience with this problem at the telehandler (SLF)? When i checked the machine via CAT ET the active code shows: 174-2 fuel temperature sensor: erratic, intermittent or incorrect 342-2 secondary engine speed sensor: erratic, intermittent or incorrect 1684-10 fuel injection pump: abnormal rate of change 1684-14 fuel injection pump: special instruction SIS states, if both codes are showing there's a fault between ECM and CAN A data link. I performed the fuel injection pump circuit test and CAN A data link circuit test but both of them passed.
Hello and welcome to HEF. First off, in order to get accurate information a serial number will be required. In the meantime, perkapillars have some traits. Mostly poor engineering, chafing in wiring and bad earth issues. Hopefully someone with access to sis will be along to give you more details on the error codes. From the information you provided the issues are around the hp pump. So i would carry out a wiggle test, check earths and open loom and have a look. Good luck
