Had a problem start recently and I don’t know if there’s a fix for it or what the fix is. Hoping someone here has had experience with it. I thought I tracked down these strange electrical issues to a bad battery. Replaced the battery and everything was good for a couple drives. Then it started again:

Shut the engine off and the car keeps running fire about 10 seconds after shutting off

Rear view mirror stays on (passenger air bag light, compass and green led)

Selective ride light stays on

Something behind dash is running too (fan on radio?)

Push button start light stays on


Anyone have any ideas or experience? These literally won’t turn off unless the battery is disconnected. If I disconnect, wait a while then reconnect these stay off. But once I run the car they stay on again. The only thing I’ve installed recently electrical related is a DSX Aux pump, but it hasn’t been activated yet

Mines done the same thing once after it was being tuned all day, i unplugged the battery for a few minutes and it never happened again, i have no idea why it happened unfortunately, I thought maybe the battery was really drained from it being at the shop all day, but who knows, both my zr1 and ZO6 have had odd electrical issues that sort of went away on their own.
Good luck, hopefully it's just something like a loose ground

SIK02SS

Thanks me too. Grounds are going to be the next thing to check. I doubt it’s the problem, but it’s easy to check so may as well

Maybe a bad ignition switch?

That sucks brother... Did you have this issues "prior" to the Aux pump...? Keep us posted..

SIK02SS

No, but like I said the aux pump isn't even activated, just installed. IMO highly unlikely to be related, I'll pull the power on it later and verify while checking grounds

SIK02SS

someone mentioned that on facebook. I'll look into it more

Did you check to see if your battery is getting charged properly? It's likely not an issue that works for 3 drives after replacing a battery and then acts up again.
​​​​​​Could be an ecu issue too, make sure all your fuses in the engine bay are in tight and connections under the passenger side floor board are tight. Check alternator connection

Dash showed it was charging, but I'll re-check those as well thanks. After reading more on ignition switch (after I bought one..) I don't think that's it at all. It was cheap enough and the finish on mine is wearing so what the hell. It's sending the signals, but a module isn't properly responding it seems. In a different/older post but similar circumstances (with no conclusion posted) it was mentioned a possible wire issue between BCM and ECU. So ya, this could be fun.

Ryne said it was nothing tune related, but I guess that doesn't rule out ECU issues per sey, but no codes being thrown either.
