HYBRID CONTROL SYSTEM Pattern Select Switch Circuit

DESCRIPTION

The pattern select switch is built into the combination switch assembly. Pattern select switch signals are sent to the outer mirror switch assembly via LIN communication. The signals are then sent to the hybrid vehicle control ECU via CAN communication. If pattern select switch signals are input to the hybrid vehicle control ECU, the ECU sends signals to the combination meter assembly via CAN communication to turn on the corresponding mode light.
