HOW TO USE THIS MANUAL GENERAL 00-3 HOW TO USE THIS MANUAL M1001000103302 SCOPE OF MAINTENANCE, REPAIR AND SERVICING EXPLANATIONS This manual provides explanations, etc. concerning procedures for the inspection, maintenance, repair and servicing of the subject model. Note, however, that for engine and transmission-related component parts, this manual covers only on-vehicle inspections, adjustments, and the removal and installation procedures for major components. For detailed information concerning the inspection, checking, adjustment, disassembly and reassembly of the engine, transmission and major components after they have been removed from the vehicle, please refer to sepa- rate manuals covering the engine and the transmission. ON-VEHICLE SERVICE "On-vehicle Service" is procedures for performing inspections and adjustments of particularly important locations with regard to the construction and for maintenance and servicing, but other inspection (for looseness, play, cracking, damage, etc.) must also be performed. INSPECTION Under this title are presented inspection and checking procedures to be performed by using special tools and measuring instruments and by feeling, but, for actual maintenance and servicing procedures, visual inspections should always be performed as well. DEFINITION OF TERMS STANDARD VALUE Indicates the value used as the standard for judging the quality of a part or assembly on inspection or the value to which the part or assembly is corrected and adjusted. It is given by tolerance. LIMIT Shows the standard for judging the quality of a part or assembly on inspection and means the maximum or minimum value within which the part or assembly must be kept functionally or in strength. It is a value established outside the range of standard value. REFERENCE VALUE Indicates the adjustment value prior to starting the work (presented in order to facilitate assembly and adjustment procedures, and so they can be com- pleted in a shorter time). DANGER, WARNING, AND CAUTION DANGER, WARNING, and CAUTION call special attention to a necessary action or to an action that must be avoided. The differences among DANGER, WARNING, and CAUTION are as follows: • If a DANGER is not followed, the result is severe bodily harm or even death. • If a WARNING is not followed, the result could be bodily injury. • If a CAUTION is not followed, the result could be damage to the vehicle, vehicle components or service equipment. INDICATION OF TIGHTENING TORQUE Tightening torques (units: N⋅m) are set to take into account the central value and the allowable tolerance. The central value is the target value, and the allowable tolerance provides the checking range for tightening torques. If bolts and nuts are not provided with tightening torques.

HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS GENERAL 00-6 HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS CONTENTS OF TROUBLESHOOTING M1001013300794 CAUTION During diagnosis, a diagnosis code associated with other system may be set when the ignition switch is turned on with connector(s) discon- nected. On completion, confirm all systems for diagnosis code(s). If diagnosis code(s) are set, erase them all. WARNING Since the radiator fan rotates during CAN bus line diagnostics, make sure that no one is servicing the engine compartment before diagnosing the CAN bus line. Since the CAN communication stops when diagnosing the CAN bus line, the ETACS-ECU detects the time-out of the engine-ECU, and activates the radiator fan to prevent overheating as fail-safe. Troubleshooting of electronic control systems for which the M.U.T.-III can be used follows the basic outline described below. Even in systems for which the M.U.T.-III cannot be used, some of these systems still follow this outline. 1. STANDARD FLOW OF DIAGNOSIS TROUBLESHOOTING Troubleshooting sections are based on the diagnostic flow as below. If the diagnostic flow is different from that given below, or if additional explanation is required, the details of such differences or additions will also be listed.

INSPECTION PROCEDURE BY USING AN OSCILLOSCOPE When there are inspection procedures using an oscilloscope, these are described here. DIAGNOSIS FUNCTION M1001013400865 The diagnosis function retrieves diagnosis code and service data by M.U.T.-III and enables the perform- ance of the actuator test. • DIAGNOSIS CODE • Service data sent • Actuator test • Diagnosis deletion using M.U.T.-III • Freeze frame data • Status indication by diagnosis code • ECU information display NOTE: If a diagnosis code is set, the "status indication by diagnosis code" informs users whether a mechanical problem currently exists (current trouble) or whether it existed before but normal operation has been restored (past trouble). HOW TO READ DIAGNOSIS CODE CAUTION Before connecting or disconnecting the M.U.T.- III, turn the ignition switch to the "LOCK" (OFF) position. AC509179 AB Diagnosis connector MB991827 MB991824 MB991910 <LH drive vehicles> AC501413AC Diagnosis connector MB991827 MB991824 MB991910 <RH drive vehicles> Connect the M.U.T.-III to the 16-pin diagnosis connector, and read the diagnosis code. NOTE: For details on how to use the M.U.T.-III, refer to the "M.U.T.-III operation manual." 1. Ensure that the ignition switch is at the "LOCK" (OFF) position. 2. Start up the personal computer.

HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS GENERAL 00-9 3. Connect special tool M.U.T.-III USB cable MB991827 to V.C.I. (MB991824) and the personal computer. 4. Connect special tool M.U.T.-III main harness A (MB991910) to the V.C.I. 5. Connect the M.U.T.-III main harness A to the diagnosis connector of the vehicle. 6. Turn the V.C.I. power switch to the "ON" position. NOTE: When the V.C.I. is energized, the V.C.I. indicator lamp will be illuminated in a green col- our. 7. Start the M.U.T.-III system on the personal computer and turn the ignition switch to the "ON" position. 8. Read the diagnosis code. NOTE: When storing the diagnosis code as reference information, the freeze frame data obtains the data when the diagnosis code is confirmed, and then stores the ECU status of that time. By analysing each data using M.U.T.-III, troubleshooting can be carried out efficiently. 9. Disconnecting the M.U.T.-III is the reverse of the connecting sequence, making sure that the ignition switch is at the "LOCK" (OFF) position. ERASING DIAGNOSIS CODE CAUTION Before connecting or disconnecting the M.U.T.- III, turn the ignition switch to the "LOCK" (OFF) position. Connect the M.U.T.-III to the diagnosis connector, and erase the diagnosis code. The procedure is the same as "How to Read Diagnosis Code ." HOW TO USE THE INSPECTION PROCEDURES M1001013500345 The causes of many of the problems occurring in electric circuitry are generally the connectors, components, the ECU, the wiring harnesses between connectors, in that order. These inspection procedures follow this order. They first try to discover a problem with a connector or a defective component.
