parts catalog for the vehicle model Please refer to the catalog for checking the part name The number at the right shoulder of each components figure indicates the Fig number in the parts catalog (Example) 3201 FIG number in parts catalog Matters omitted in this manual (1) This manual omits description of the following jobs, but perform them in actual operation: Cleaning and washing of removed parts as required Visual inspection (partially described) TERMINOLOGY Caution: Important matters of which negligence may cause accidents Be sure to observe them Note: Important items of which negligence may cause accidents, or matters in operation procedure requiring special attention Standard: Values showing allowable range in inspection and adjustment Limit: Maximum or minimum allowable

in the past, for smoother international technical communication New Units Adopted in SI Conversion rate*1 (1 [conventional unit] = X [SI unit]) Characteristic New unit Conventional unit Force*2 N (newton) kgf Torque*2 (moment) N•m kgf•cm kgf•cm = 9.80665 N•m Pressure*2 P (pascal) kgf/cm2 kgf/cm2 = 98.0665 kPa = 0.0980665 MPa ↑ ↑ mmHg mmHg = 0.133322 kPa Revolving speed r/min rpm Spring constant*2 N/mm kgf/mm Volume L cc cc = mL Power W PS PS = 0.735499 kW Heat quantity W•h cal kcal = 1.16279 W•h Specific fuel consumption g/W•h g/PS•h kgf = 9.80665 N rpm = r/min kgf/mm = 9.80665 N/mm g/PS•h = 1.3596 g/kW•h *1: X represents the value in SI unit as converted from [in conventional unit], which can be used as the rate for conversion between conventional and SI units 2: * In the past, kilogram [kg] representing the mass was often used in place of weight kilogram [kgf] that should be used as the unit of force Conversion between Conventional and SI Units Value in SI unit = Conversion rate × value in conventional unit Value in conventional unit = Value in SI unit ÷ Conversion rate Conversion rate: Figure corresponding to X in the conversion rate column in the table above Caution: At the time of conversion, change the unit of the value in conventional or SI unit to the one in the conversion rate column in the table above before calculation When converting 100 W to the value in conventional unit PS, change it to 0.1 kW first and divide by 0.735499 as the conversion rate 0-8 OPERATIONAL TIPS Safe operation (1) After jacking up, always support with wooden blocks or rigid stands (2) When hoisting the vehicle or its heavy component, use wire rope(s) with a sufficient reserve in load capacity (3) Always disconnect the battery plug before the inspection or servicing of electrical parts Tactful operation (1) Prepare the mechanic tools, necessary measuring instruments (circuit tester, megger, oil pressure gauge, etc.) and SSTs before starting operation (2) Before disconnecting wiring, always check the cable color and wiring state (3) When overhauling functional parts, complicated portions or related mechanisms, arrange the parts neatly to prevent confusion (4) When disassembling and inspecting such a precision part as the control valve, use clean tools and operate in a clean location (5) Follow the described procedures for disassembly, inspection and reassembly (6) Replace, gaskets, packing and O-rings with new ones each time they are disassembled (7) Use genuine Toyota parts for replacement (8) Use specified bolts and nuts Observe the specified tightening torque at the time of reassembly (Tighten to the center of the specified tightening torque range.) If no tightening torque is specified, tighten the bolt or nut according to the standard tightening torque table Protection of functional parts (1) Thoroughly check each connector for any failure in or imperfect connection before reconnecting the battery plug after the end of vehicle inspection or maintenance Failure in or imperfect connection of connectors related to controllers, especially, may damage elements inside the controllers Confirming defect status Do not start immediate disassembly or replacement, but first confirm if such disassembly or replacement is actually needed Handling of waste fluid, etc When draining waste fluid from the vehicle, always receive it with an appropriate container Since careless or arbitrary discharge or disposal of oil, fuel, coolant, oil filter, battery or any other harmful substance may cause adverse affect to people or environmental destruction, sort each waste and always ask an authorized contractor for appropriate disposal Handling of electronic parts (1) Never apply impacts to electronic parts such as a microcomputer or relay (2) Never let electronic parts be exposed to a high temperature or humidity (3) Do not touch connector pins since they may be deformed or be damaged due to static electricity 19-25 P1 terminal 19-26 19-27 With voice warning Motor A Motor B N1 terminal N1 terminal 19-28 AC plug AC plug Battery capacity 48V 330 ~ 565 AH Only for battery capacity: 48V 330 ~ 565 AH AC plug AC plug Battery capacity 48V 600 ~ 845 AH, 80V 370 ~ 470 AH AC plug AC plug AC plug Timer terminal Timer terminal Timer terminal Timer terminal Timer terminal Timer terminal Timer terminal Timer terminal 19-29 1) When the lifting height is 2,000 or more, excluding 2) and 3) below [Note: Nos 1, and on the TAB side are unconnected for FV2000.] 2) When the lifting height is 4500 or more for V or SV mast vehicles with single tires for domestic market 3) When the lifting height is 4500 or more for FSV mast vehicles with single tires for domestic market 19-30 When the lifting height is 4500 or more for V or SV mast vehicles with single tires for domestic market When the lifting height is 4500 or more for FSV mast vehicles with single tires for domestic market When the lifting height is 4500 or more for V or SV mast vehicles with single tires for domestic market When the lifting height is 4500 or more for FSV mast vehicles with single tires for domestic market 19-31 19-32 19-33 Surge absorber Surge absorber N1 terminal 19-34 For volume selectable buzzer Forward/reverse travel chime DM Wiper motor Wiper (Options shown in this circuit diagram also apply to vehicles with SAS.)
