HYBRID / BATTERY CONTROL  HYBRID CONTROL SYSTEM  TRAIL Switch Circuit  


DESCRIPTION

The TRAIL mode signal will be sent to the hybrid vehicle control ECU assembly when the TRAIL mode switch (integration control and panel assembly) is operated. If the specified conditions are met, the system enters TRAIL mode and the vehicle will be driven using TRAIL mode. This signal is then transmitted from the hybrid vehicle control ECU assembly via CAN to the combination meter assembly to illuminate the TRAIL indicator.
