Toyota Venza: Power Source Circuit
DESCRIPTION
1. w/o Multi-information Display
(a) This circuit is the power source circuit for the accessory meter assembly. This circuit provides two types of power sources; one is a constant power source mainly used as a backup power source, and the other is a power source mainly used for signal transmission.
HINT:
If the accessory meter assembly displays "1:00" when the ignition switch is turned off, then to ON again, the B terminal has a malfunction.
The maximum clock assembly margin of error is -4 to 4 seconds per day when the temperature is between -20°C (-4°F) and 60°C (140°F).
