ACTION REQUIRED
Group 1 Only: REWORK HYDRAULIC PRESSURE MONITORING SYSTEM Rework the hydraulic pressure monitoring system per Special Instruction M0115605: "Procedure to Install Updated Propel Pump Wiring Harness and Pressure Sensors on Certain Cold Planers." Group 2 Only: These group of machines were previously reworked with the new harnesses, pressure sensors relocation and earlier revision of the software. Not all of the parts listed in the special instruction are required. The original pressure sensors should still be in place. They may be removed from the front left and rear left propel motors and their respective ports plugged. The new location for the diagnostic pressure tap need to be added to right front and right rear motors. Use the plugs removed from the right side motors pressure ports to plug the ports on the left side motors from which the pressure sensors have been removed. Remove left and right front track motor access covers. Remove left and right rear track motor access covers. Refer to Steps 22 "Rework right side front and rear track motors" and 23 "Rework left side front and rear track motors" in Special Instruction M0115605: "Procedure to Install Updated Propel Pump Wiring Harness and Pressure Sensors On Certain Cold Planers" for guidance on how to perform the rework. Reinstall left and right rear track motor access covers. Reinstall left and right front track motor access covers. Group 1 and 2: UPDATE TRANSMISSION SOFTWARE Note: Always use the latest software available. Sometimes the flash file part numbers are updated before the program terminates. Flash the 598-2772 Transmission Software into the Transmission ECM using Cat ET. Perform the "Propel Pump Pressure Override- Calibrate" procedure, refer to testing and adjust media number: UENR6292-04 (or later). Perform the "Propel Current-Calibrate" procedure, refer to testing and adjust media number: UENR6292-04 (or later). Note: After the calibration procedures have been successfully performed, turn the key switch and main disconnect switch to OFF and then back ON, wait for the system to boots up, if "Drive Circuit #1 Forward Pressure Sensor - Calibration Required" or "Drive Circuit #2 Forward Pressure Sensor - Calibration Required" or both show up proceed to repeat "Propel Pump Pressure Override- Calibrate" procedure. Note: In order to complete the machine configuration changes, Cat ET 2019C or later is needed. See release notes for a list of improvements and issue resolutions included in each software update. |
