Changing digital readout from Centigrade to Fahrenheit

Fri Aug 03, 2018 5:19 pm

I have tried to reset the Centigrade temp readout to Fahrenheit over and over again, but each time that I have it reading Fahrenheit correctly, when I turn off the car and restart it defers to Centigrade again. How do I make it stick to Fahrenheit permanently?

I had this problem when I first started driving my leased 2015 Spark EV. You will have to take your Spark EV to the dealer and have them reprogram the RADIO USB per BULLETIN P1457, DOC 4109861 CODE S13991875B30

I also noticed that, when driving in L at night, it took about 1.5 seconds for the brake lights to come on after I removed my foot from the accelerator pedal. This is way too long if you are traveling at freeway speeds. This was corrected through BULLETIN 15582, RECALL CAMPAIGN S1024837559A.

You may want to ask your dealer to update your Spark EV to all of the available updates. There have been a number of them.

I had no problem with dropping it from 5th or 6th into 3rd or 2nd if I wanted to slow down in a hurry without the tactical disadvantage of brake lights coming on. I could not help the deceleration exhaust note (quite pleasant in my 2006 Honda Civic SI), but hey.

If I want brake lights, I'll step on the brake pedal, thank you. Honestly, as someone that dearly misses downshifting, I'd prefer that the brake lights only come on if I am actively pressing the brake pedal.

Again, they are brake lights, not deceleration lights, thank you.

Are you actually driving a Spark EV?? If you are and have any knowledge of the car, you would know that when driving in L, quickly removing your foot off of the accelerator will automatically turn on the brake lights if the deceleration g-force caused by regeneration exceeds Chevy's programmed limit.

My point is that the car was delivered with about a 1.2-1.5 second delay between removing your foot off of the accelerator and when the brake lights would go on. I found this delay confused some drivers behind me and apparently other Spark EV drivers had the same concern. Chevy issued a service bulletin to reduce the delay so the brake lights come on just as if you touched the brake pedal. Benjamin Franklin had nothing to do with this!

"Tactical Disadvantage" ? :lol:
Which game or competition are you talking about? :?:

When on a commute we're all in it together. There are no winners or losers.
Brake lights/decel lights = equal the exact same thing. :roll:

The idea is to make the world of commuting a safer place for all,,,, not 'every man for himself' :)
Used '14 2LT w/ DCFC. +73 K miles.
Mostly free charging! Only one LONG visit to the shop....
GM needs Modern Troubleshooting tools for Modern EV's.
3 step Trouble Tree, 2nd guess not covered by warranty and cost $800. 3rd guess fixed the problem.

Electric Ninja Road Warrior have a nice ring to it?

I did buy a black Chevy Spark EV. It's all Ninja like.

I haven't gone so far as to buy black wheels, but recently placed an order for custom black Texas "SPARK EV" plates. Name was available, so I nabbed it! Woo hoo!

I'm a big fan of the silent acceleration that does not attract attention, and in the same spirit of not attracting attention, would prefer the same advantage for deceleration.

The one thing I really don't like about this car is the screwy electric parking brake with no tactile feel that I can discern, it is of no practical use as an emergency brake to me.

If I really wanted to stop completely with no brake lights in the ol' Civic, between downshifting and the hand lever e-brake, it took some thought and effort, but was do-able.

Being discreet during acceleration is understandable and harmless.

But I fail to see any benefit in not attracting attention to deceleration except if your goal is to create an accident...

Is speeding a crime? Granted that is not the same as discreet acceleration, but I hope you can understand the association. That said, I do quite enjoy discreet acceleration!

Is stopping without brake lights a crime? Not to my knowledge. Of course it is generally unsafe.

Stopping without brake lights (dead battery, jump start to get home, car dies on the way home, no lights) brought an end to my 1989 Honda CRX. I didn't even have time to get out before I was rear ended.

I still want the freedom to choose to stop without brake lights. There may be a situation where such an action is best. Street smarts safety is my specific concern. I won't go into details, but it involves being the victim of a violent crime in my past. I hope you can understand that I feel strongly about this and why, but not so strongly to completely ditch my Chevy Spark EV over it. In the end, I did survive both cases.

The original question posted regarded how to fix the display so it would display deg. F and not default to deg. C. I provided that information and included information regarding a fix for the brake light delay which occurs when you are driving in L and remove your foot from the accelerator. This action is built into every Spark EV. If you do not want the brake lights to come on until you step on the brake pedal, drive in D!
