TROUBLESHOOTING / Diagnosing Procedure INTRODUCTION Refer to the inspection and troubleshooting proce- dures after any machine trouble has occurred. The inspection and troubleshooting procedures are pre- sented in an orderly fashion in this section to quickly find the cause of the machine trouble and solution. The troubleshooting section in this manual consists of 8 groups; Diagnosing Procedure, monitor unit, Dr. ZX, e-Shovel, Component Layout, Troubleshooting A (base machine diagnosis by using fault codes), Trouble- shooting B (base machine diagnosis starting with in- spection of abnormal operational status) and Electrical System Inspection.
Monitor Unit Refer to this group as for the display screen and operating procedures of monitor unit. Dr. ZX This group contains the operating procedures for Dr. ZX. e-Shovel This group contains as follows. Download data from ICF and Upload Procedures when starting satellite communication, when installing the satellite communication con- troller and when replacing ICF Explanation for the satellite communication sys- tem Component Layout Troubleshooting A (base machine diagnosis by using fault codes) Refer to these procedures if any fault codes are displayed when each controller (MC, ECM, ICF and monitor unit) is diagnosed by using Dr. ZX (or the service menu of monitor unit). IMPORTANT:
ICF receives and retains a record of the electrical signal system mal- function of each controller in the form of fault codes by using CAN communication. In addition, ICF self-diagnosing function records the electrical signal system malfunction in the form of fault codes Ex.) Fault Code 11004-2: Failure of CAN Com- munication Troubleshooting B (base machine diagnosis start- ing with inspection of abnormal operational status) Refer to these procedures when no fault codes are displayed after diagnosing the machine with Dr. ZX (or the service menu of monitor unit). Ex.) Although the engine control dial is turned, engine speed does not change.
Electrical System Inspection Refer to this group when required to obtain pre- cautions and/or information for the electrical sys- tem inspection. Ex.) Fuse Check T5-1-1
