ACTION REQUIRED
The new 563-3817 Powertrain Software has improvements for reducing the clutch energy on Clutch 4. This or the latest chassis software available on SIS Web must be installed. The new software is available in the form of a flash file through Caterpillar Service Information Systems (SIS). Go to SIS Web to make sure 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. It is recommended to update the Advisor Software to 552-6122 Monitor Software Gp which has improved logic for -7 code check engine lights. Flash the new 563-3817 Software onto the Powertrain ECPC ECM. Flash the appropriate engine software onto the engine ECM (either 548-4809 or 548-4808 depending if it is Tier 2 or LRC). Refer to the Service Manual if/as necessary. NOTE: Transmission recalibration is not required. NOTE: Always use the latest software available. Sometimes the flash file part numbers are updated before the program terminates. |
