- PRECAUTIONS FOR INSPECTING HYBRID CONTROL SYSTEM Before inspecting or servicing the high-voltage system or disconnecting the low voltage connector of the inverter with converter assembly, be sure to follow all safety measures, such as wearing insulated gloves and removing the 3 service plug grips to prevent electrocution. After removing the 3 service plug grips, carry one of the 3 service plug grips in your pocket to prevent other technicians from accidentally reconnecting it while you are servicing the vehicle. Keep the other 2 service plug grips in a secure place. WARNING: Be sure to wear insulated gloves. Be sure to remove the 3 service plug grips before beginning work. Since the HV battery assembly contains 3 batteries that are connected in parallel, the circuit will not be interrupted if any of the service plug grips remain connected. NOTE: After removing the service plug grips, turning the power switch on (READY) may cause a malfunction. Do not turn the power switch on (READY) unless instructed by the repair manual. After removing the service plug grips, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. HINT: Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly and the electric vehicle charger assembly. Check the voltage at the terminals in the inspection point in the inverter with converter assembly. WARNING: Be sure to wear insulated gloves. Remove the 9 bolts and inverter terminal cover. Refer to «COMPONENTS»(ref-393418-S25485313402011040700000). NOTE: Cover the opening with non-residue tape to prevent entry of foreign matter or liquid after removing the connector cover. Measure the voltage according to the value(s) in the table below. Standard Voltage Tester Connection Condition Specified Condition Inspection point 10 minutes passed after removing the service plug grips 0 V HINT: Set the tester to DC750 V or more to measure the voltage. When turning the power switch on (IG) during inspections, do not press the power switch with the brake pedal depressed. WARNING: Pressing the power switch with the brake pedal depressed causes the system to enter the READY-on state. This is very dangerous because high voltage may be applied to the inspection area. Turn the power switch off, wear insulated gloves, and disconnect the cable from the negative (-) terminal of the auxiliary battery before touching any of the orange-colored wires of the high-voltage system. Turn the power switch off before performing any resistance checks. Turn the power switch off before disconnecting or reconnecting any connectors. When high-voltage connectors are removed, wrap the connectors with insulation tape to prevent them from contacting foreign objects.
- NOTICE FOR HYBRID CONTROL SYSTEM ACTIVATION When the warning light is illuminated, or the auxiliary battery has been disconnected and reconnected, attempting to turn the power switch on (READY) may not start the system (the system may not enter the READY-on state) on the first attempt. If so, turn the power switch off and reattempt to start the hybrid system.
- FOR USING TECHSTREAM WARNING: Observe the following items for safety reasons: Before using the Techstream, read the instruction manual. Prevent the Techstream cable from being caught on the pedals, shift lever or steering wheel when driving with the Techstream connected to the vehicle. When driving the vehicle for testing purposes using the Techstream, 2 persons are required. One is for driving the vehicle, and the other operates the Techstream.
- DISCONNECTING AND RECONNECTING NEGATIVE BATTERY CABLE Before performing work on electronic components, disconnect the cable from the negative (-) battery terminal to prevent damage to the electrical system or electrical components. TEXT IN ILLUSTRATION *1 Negative (-) Battery Terminal *2 Cable Before disconnecting and reconnecting the battery cable, turn the power switch off and the headlight switch off. Then loosen the terminal nut completely. Do not damage the cable or terminal. When the battery cable is disconnected, the clock and radio settings and stored DTCs are cleared. Therefore, before disconnecting the battery cable, make a note of them.
