I've replaced all of my front and turn signal lights with LEDs over the past year. The most recent being the front turn signals to 7443 7444 CANBUS Error Free Anti Hyper Flash Switchback LED Turn Signal Light Dual Color Blinkers. Now my info cluster message screen is flickering off and on intermittently with the error message "CHECK CHARGING SYSTEM". I had the charging system checked and it pointed to a bad battery. I replaced the battery and I am still receiving the same error message. Has anyone else had this same issue after upgrading to LEDs?

 

The message means the cars electrical system is running off the battery.

Have you tried switching back to the old lights? Doubt this is the issue.

When does the light come on? At idle, at idle with headlights and heater on, when a turn signal is on?

What happens to the message if you rev the engine up? Does it go away?

Do you have a voltmeter? If so check voltage at the battery engine running at idle then at 2000 rpm.

Flickering message could be the voltage is varying. Could be a failing alternator or as bad connection with the battery cables.

 

Thank you for taking the time to reply. No I have not swapped them back...yet. I will tho. It's intermittent but somewhat frequent. AC on, at 35 and interstate. I took the car to NAPA and they said it was the battery and the alternator looks good, so I swapped that, but it did not fix the issue.

 

One can buy a small digital voltmeter that plugs into the cars cig or power out. You can then monitor the voltage to determine if it changes significantly when the warming comes on.

Do all lights flash when the emergency lights are set?

just bought this car, it didn’t have key fobs so I bought a couple from an auto locksmith but they won’t program to the car properly. They thought it had something to do with the same error message you’re getting. I thought perhaps the battery was bad so I replaced the battery….still the same error message. Alternator checks out fine, but the battery isn’t putting off as much power. Any other ideas of what to check?
