MBE 4000 SERVICE MANUAL 17.2.3 Low Power Troubleshooting Chart There are three basic checks that should be performed: Check for active/historic codes. Refer to MBE DDEC Application/Installation Manual (7SA825) Appendix A (fault codes). All causes need to be checked once the fault is identified. Record faults on the Application For Adjustment (AFA) claim, if there is to be a claim. Check the VCU/PLD parameters, progressive shift settings, and torque limiting values. Are they correct? Is proper rating applied? If vehicle is new, is it spec'd correctly? Check that the dyno-measured power is within DDC specifications as listed in Table 17-3 for minimum acceptable wheel HP data.
Record data on AFA claim. NOTE: Service information letter instructions published following the date of this document take precedence. All information subject to change without notice. (Rev. 2007) 6SE412 0702 Copyright © 2007 DETROIT DIESEL CORPORATION From Bulletin 1–MBE 4000–07 17-11
