IMA Motor Power Cable Removal/Installation

IMA components are located in this area. The IMA is a high-voltage system. You must be familiar with the IMA system before working on or around it. Make sure you have read the IMA service precautions before doing repairs or service (see SERVICE PRECAUTIONS  ).

1. Make sure the ignition switch is in LOCK (0).
2. Do the 12 volt battery terminal disconnection procedure (see 12 VOLT BATTERY TERMINAL DISCONNECTION AND RECONNECTION ).
3. Remove the IPU cover (see IPU COVER REMOVAL/INSTALLATION  ).
4. Remove the bolts (A) and the PCU lid (B).

6. Open the clamp (C).
7. Remove the air cleaner (see AIR CLEANER ELEMENT INSPECTION/REPLACEMENT ).
8. Turn the ignition switch to LOCK (0).
9. Turn the battery module switch OFF.
10. Slide the protector (A) in the direction of the arrow. Push the tab (B), then raise the lever (C). Remove the IMA motor power cable (D) from the motor stator.
    NOTE:

    • If the outside of the IMA motor power cable connector is dirty, clean it before you disconnect it.
    • Cover the disconnected connector (E) with a plastic bag (F), and wrap the IMA motor power cable terminals with tape (G).
    • If the IMA motor power cable terminals are wet, dry them with a clean shop towel. Do not use compressed air.
