Comprehensive improvements have been made to the M.U.T.-II, a tester for diagnosing problems with the electronic control system. For easier servicing, the newly developed M.U.T.-III has greatly improved functions and is much easier to use. The M.U.T.-III expands the functions of the M.U.T.-II in the following ways:
Interactive Error Diagnosis
In response to the nature of the problem, the corresponding troubleshooting page from the maintenance manual is retrieved.
Service data is displayed, and from the actuator test screen, the page of the maintenance manual is retrieved for a list of inspection reference values.
Service Manual Viewer
The technical information manual and workshop manual can be displayed on a personal computer monitor.
CAN* bus diagnosis
Auto diagnosis function for the CAN communications bus line.
note
*CAN: Controller Area Network (for further details, refer to GROUP 54C ).
IMPROVED SERVICEABILITY
Since adoption of unvolatile memory (EEPROM*) helps the learned value not to be initialised when the battery terminal or connector of the control unit is disconnected, maintainability can be improved.
note
*EEPROM: Electrical Erasable Programmable ROM (information to be memorised can be electronically written into and erased from ROM)
Since the adoption of service hole at the quarter trim is designed for removal and installation of the rear shock absorber assembly, maintainability can be improved.
Since the adoption of electric power steering makes hydraulic pipes and oil pumps unnecessary, maintainability can be improved.
Since adoption of service hole at the splash shield helps for removal and installation of headlamp bulb (low beam) and front turn signal lamp bulb, maintainability can be improved.
The instrument lower panel can be removed or installed without using tools at the time of fuse replacement in the junction block.
