Toyota Venza: Clock Display Circuit
DESCRIPTION
The accessory meter assembly uses this circuit to communicate with the combination meter assembly via the direct line. The accessory meter assembly uses this circuit to receive the drive monitor switch signals from the combination meter assembly via the direct line and multi-information display signal from each ECU through the combination meter assembly via the direct line.
HINT:
Each ECU outputs the DTCs when each system has a malfunction.
