HOW TO USE THIS MANUAL GENERAL 00-2 HOW TO USE THIS MANUAL M1001000101016 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, refer to P.00-37. MODEL INDICATIONS The following abbreviations are used in this manual for identification of model types. 2500:Indicates an engine with the 2,477mL <4D56> diesel engine. 3200:Indicates an engine with the 3,200mL <4M41> diesel engine. DOHC: Indicates an engine with the double over- head camshaft. M/T:Indicates the manual transmission. A/T:Indicates the automatic transmission. A/C:Indicates the air conditioner.

AC311239 35A-21 Classifications of major maintenance / service points When there are major points relative to maintenance and servicing procedures (such as essential maintenance and service points, maintenance and service standard values, information regarding the use of special tools, etc.). These are arranged together as major maintenance and service points and explained in detail. <<A>> : Indicates that there are essential points for removal or disassembly. >>A<< : Indicates that there are essential points for installation or reassembly. Operating procedures, cautions, etc. on removal, installation, disassembly and reassembly are described The title of the page (following the page on which the diagram of component parts is presented) indicating the locations of lubrication and sealing procedures. Indicates (by symbols) where lubrication is necessary. Symbols for lubrication, sealants and adhesives Symbols are used to show the locations for lubrication and for application of sealants and adhesives. These symbols are included in the diagram of component parts or on the page following the component parts page. The symbols do not always have accomp- anying text to support that symbol. Adhesive tape or butyl rubber tape Grease (Multi-purpose grease unless there is a brand or type specified) Sealant or adhesive Brake fluid or automatic transmission fluid Engine oil, gear oil or air conditioning com- pressor oil AB HOW TO USE THIS MANUAL GENERAL 00-4

HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS GENERAL 00-5 HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS CONTENTS OF TROUBLESHOOTING M1001013300211 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.

Connect the M.U.T.-III main harness A to the diagnosis connector. 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. 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). ERASING DIAGNOSIS CODE CAUTION Before connecting or disconnecting the M.U.T.-III, turn the ignition switch to the "LOCK" (OFF) position. AC501413AB Diagnosis connector MB991827 MB991824 MB991910

HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS GENERAL 00-8 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 M1001013500237 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.
