ELECTRONIC SHIFT LEVER SYSTEM Auxiliary Battery Low Voltage

DESCRIPTION

If the transmission control ECU assembly judges that the power source voltage (+B) is low (including due to a depleted auxiliary battery), or the meter ECU detects a malfunction of the CAN communication system (communication stop), a warning message is displayed on the combination meter sub-assembly (w/o Multi-information Display).

When the transmission control ECU assembly judges that the power source voltage (+B) is low (including due to a depleted auxiliary battery), a warning message is displayed on the multi-information display (w/ Multi-information Display).
