Repair Instruction: Initialization: Initialization

  1. PROCEDURES NECESSARY WHEN BATTERY TERMINAL IS DISCONNECTED/RECONNECTED 
    NOTE:

    When the auxiliary battery is replaced or the cable is disconnected from its negative (-) battery terminal, the ISC learning value will be initialized and symptoms as a loud rattle from the hybrid vehicle transaxle assembly may occur until ISC learning is performed. Therefore, perform ISC learning when the auxiliary battery is replaced or the cable is disconnected from the negative (-) terminal of the auxiliary battery. Refer toLoud Rattle from Hybrid Vehicle Transmission .
