    MODELCHASSIS CODEYM
    CR-ZZF111, 12
    INSIGHTZE210, 11, 12
    Jazz HYBRIDGP112, 13

    The Symptom
    - Battery charge indicator decreases suddenly with reduction in available IMA assist.
    - IMA warning light is on with DTC P0A7F only.

    The Cause
    Memory effect of the IMA battery causes a change to the discharge voltage. This voltage change causes the ECU to miscalculate the IMA battery usable capacity and subsequently reduce the available IMA assist during driving.

    The Fix
    Reprogramming of the IMA motor ECU.
    Application to Production Line
