Section 518 (Hybrid Battery System (Diagnostics)): Precaution
WARNING: This page is about a different car, the 2004 Toyota Prius. However, it is still accessible from the selected car via links, so may be relevant.
- Precautions for inspecting the hybrid battery system
- Before inspecting the high-voltage system, take safety precautions to prevent electrical shocks, such as wearing insulated gloves and removing the service plug grip (see PRECAUTION
). After removing the service plug grip, put it in your pocket to prevent other technicians from reconnecting it while you are servicing the high-voltage system.NOTE: Turning the power switch ON (READY) with the service plug grip removed could cause a malfunction. Therefore, do not turn the power switch ON (READY) unless instructed by the repair manual.
- After disconnecting the service plug grip, wait for at least 5 minutes before touching any of high-voltage connectors or terminals.
HINT:
At least 5 minutes is required to discharge the high-voltage condenser inside the inverter.
- Since liquid leakage may occur, wear protective goggles when checking inside the HV battery.
- Wear insulated gloves, turn the power switch OFF, and disconnect 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 a resistance check.
- Turn the power switch OFF before disconnecting or reconnecting any connector.
- To install the service plug grip, the lever must be flipped and locked downward. Once it is locked in place, it turns the interlock switch ON. Make sure to lock it securely because if you leave it unlocked, the system will output a DTC pertaining to the interlock switch system.
- Before inspecting the high-voltage system, take safety precautions to prevent electrical shocks, such as wearing insulated gloves and removing the service plug grip (see PRECAUTION
). After removing the service plug grip, put it in your pocket to prevent other technicians from reconnecting it while you are servicing the high-voltage system.
- NOTICE FOR INITIALIZATION
When disconnecting the negative (-) battery terminal, initialize the Power Window Control System after the terminal is reconnected.
- NOTICE FOR HYBRID SYSTEM ACTIVATION
- When the warning lamp is illuminated or the battery has been disconnected and reconnected, pressing the power switch may not start the system on the first attempt. If so, press the power switch again.
- With the power switch's power mode changed to ON (IG), disconnect the battery. If the key is not in the key slot during reconnection, DTC B2799 may be output.
