Subaru BRZ interior clock wrong

[csol]

Hey guys just running into a very strange issue with my interior clock.

It keeps going out of sync, i first noticed it when i removed the negative terminal. Which is fair enough but i sent the time back and observed the car overnight my internal dashcam was still on so there was power to that which cuts off at 11.8v so its not that which is draining causing it.

Woke up checked the car by turning on ignition (two button presses)

Clock is like 35min infront of what it should be

I have no idea why this is happening

I can add that i replaced my headlights and the car has a hyperblinker so waiting to replace blinker module but i doubt that connects to the clock

The hyper blink is affecting the flux capacitor. But you already knew this because you are 35 min in the future.

Simple solution, your out of blinker fluid. Just top it off and you should be good to go


I'm a big fan of this stuff:

Bunch of smart asses here -

I'd suggest you check the clock that you're using to calibrate your car's clock and make sure it's in sync with the atomic clock.

Then set the clock in your car again, this time, sober.

Maybe check the fuse that controls that circuit.

Your car is fucked. Burn it, don't even bother trying to sell it no person will buy a car with out a working clock.

If you keep driving your clock is going to explode. The way the clock sits it's going right towards your nuts. For the love of everything holy save your nuts.


Keep in mind any new Civic SI don't have these bullshit problems.

I've had an issue where my clocks (car and phone) have a one-hour difference and it causes me confusion as well. Pretty sure it's my phone, I noticed it switch over one time when I climbed a mountain road.

You might want to set your voltage threshold a but higher on that dashcam, 11.8 is very low. 12v lead acid batteries are considered full at 12.8 and discharged at 12.1.

Also, clocks like the ones in these cars are usually very simple, with just a power and ground to keep time, there are no external workings to it. The shop manual states if it loses our gains time rapidly, replace it.

Thanks for the serious answers.
I will check the fuse for the clock but it should be fine otherwise it wouldnt be on.

This issue is very strange because its out of sync and I was wondering could it be a grounding issue? I ran some wires to a module for my headlights called BlueGhozt (its fused)

I'll change the powercut so its not less than 12v

Will update

The clock is running fast it seems.
Not a battery issue i believe.
We syncd it and it ticks time faster than expected

[why?]

these things are dirt cheap, if your car is new I am sure it is covered by the warranty, just take it to the dealer and get it replaced.

The speed of the clock isn’t based on battery voltage. It would lose time every time you parked and speed up every time the alternator kicked in.

The clock would probably run down to 6 or 7 volts. If it’s on, it’s working. I would replace the clock.

Watch this, proof its out of sync

It makes sense if its 30secs out of sync then 5 hours later it makes a big difference.

I have no idea how this happened, my guess is me pulling off battery terminal caused a surge or something that fried one of the clock components.
Any ideas cause I'm lost.
Will be calling up Subaru to get them to have a look.

Digital clocks use a high frequency oscillator to divide down and create a time beat to run the clock.

If the clock is an AC wall or desk clock or even an appliance like a microwave, they use the 60 Hz or 50 Hz line frequency for that time base.

Watches and other devices (i.e., car clocks) not on the AC line use an internal high frequency oscillator that is divided down to 60 Hz or some multiple.

If your clock is is the latter, then you probably have a failing oscillator.

If it is the former, then something is bad in the 60/50 Hz line frequency detection circuitry.

^ could this be true

[DarkPira7e]

You need to close some tabs dude

I am sure the place that Subaru bought the 1986 vintage clocks still have them in stock.
