4 WR RT VT VR TR SYSTM < SYSTM SRT > WR RT VT VR TR SYSTM System iagram : M0057 System escription : ower generation variable voltage control system has been adopted. y varying the voltage to the generator, engine load due to power generation of the generator is reduced and fuel consumption is decreased. T: When any malfunction is detected in the power generation variable voltage control system, power generation is performed according to the characteristic of the regulator in the generator. omponent escription : omponent part attery current sensor M M /R enerator ( regulator) escription The battery current sensor is installed on the battery cable at the negative terminal. The battery current sensor detects the charging/discharging current of the battery and sends a voltage signal to the M according to the current value detected. The battery current sensor detects the charging/discharging current of the battery. The M judges the battery condition based on this signal. The M judges whether to request more output via the power generation voltage variable control according to the battery condition. When performing the power generation voltage variable control, the M calculates the target power generation voltage according to the battery condition and sends the calculated value as the power generation command value to the M /R. The M /R converts the received power generation command value into a pulse width modulated (WM) command signal and sends it to the regulator. The regulator controls the power generation voltage by the target power generation voltage based on the received WM command signal. When there is no WM command signal, the generator performs the normal power generation according to the characteristic of the regulator. Revision: anuary

19 < RUT > RUT RUTS RUTS recaution for Supplemental Restraint System (SRS) "R " and "ST T R-TSR" : The Supplemental Restraint System such as R and ST T R-TSR, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. nformation necessary to service the system safely is included in the SR and S section of this Service Manual. WR: To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized SS/T dealer. mproper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. or removal of Spiral able and ir ag Module, see the SR section. o not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. RUTS W US WR TS (R R TR) MMRS WR: When working near the irbag iagnosis Sensor Unit or other irbag System sensors with the gnition or engine running, T use air or electric power tools or strike near the sensor(s) with a hammer. eavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. When using air or electric power tools or hammers, always switch the gnition, disconnect the battery, and wait at least 3 minutes before performing any service. recaution for ower eneration Voltage Variable ontrol System : UT: or this model, the battery current sensor that is installed to the battery cable at the negative terminal measures the charging/discharging current of the battery, and performs various controls. f the electrical component or the ground wire is connected directly to the battery terminal, the current other than that being measured with the battery current sensor is charging to or discharging from the battery. This condition causes the malfunction of the control, and then the battery discharge may occur. o not connect the electrical component or the ground wire directly to the battery terminal.
