Hybrid Vehicle Control
CHECK MILa. The MIL illuminates when the ignition switch is turned to the ON position and the "READY" light is off.
If the MIL is not illuminated, troubleshoot the MIL circuit.
b. When the "READY" light turns on, the MIL should turn off. If the MIL remains on, the diagnosis system has detected a malfunction or abnormality in the system.
