Network ‘‘Loss of Communication'' Error Checking Function
The ECUs on the CAN circuit send messages to each other. If there are any communication malfunctions on the network, the multi-information display on the gauge control module (tach) can indicate the error messages by entering the gauge control module self-diagnostic function.
  • Error 1: F-CAN communication line error
  • Error 2: B-CAN communication line error
  • Error 3: UART communication lines error
