Lcd Clock Resets: Help

Recommended Posts

Anyone here encountered the problem with the LCD clock resetting every time you start the engine? I have a 2000 RX300 and recently the clock have been resetting everytime I turn off the car for more than a few minutes to 1:00AM. Does the LCD keep its own set of batteries or should I replace the entire LCD for a new one?

your power supply is the problem.

first check all fuses

second, take out the clock and test the voltage. theres three wires to the clock. 1 ground, 2 constant 12v b+, and 3 is ACC power-power when key ON
