Hello people,

Kindly note that I have an error code 84 on my display everytime I start the vehicle. I'm aware of the fact that it means " engine reduced power", but what does it really mean? What is the cause of this error and how to fix?

Thanks in advance for your help.

Dear all, I own the 2011 version and it seems that there is a new version of software for the Cruze?!

System has been upgraded by the dealaer for free and error has been fixed.

Case closed. Thanks anyway. Cheers

We had the same code a few months back shortly after the car was due for its first inspection service. Anywhoo...service department advised that if the service code is not cancelled after servicing, then you get code 84 because the ecu assumes you havent serviced the car so the ecu automatically reduces engine power to protect the engine.

should I interpret this that if I replace the engine oil by myself and not reset the ECU service code the engine will later go into reduced power for no reason?

Assuming what the service department advised was correct, then I guess that may well be the case (which would be annoying). But surely there must be another way of resetting the service interval reminder/auto protect function? its definately the first that I've heard of a car "reducing power" to save itself from late servicing? Pretty sure VW's don't have that feature but at least you can manually or electronically reset the service interval reminder yourself.

Found on Internet. Not sure if it works on Cruze (most likely it does). And I think it is not recommended either.

"Disconnect the negative battery cable from the battery, leave it off for one hour then reconnect it. This will dump any temporary memory your Chevy's computer has stored. It will also generate a pass code that will clear itself after driving the vehicle for a few days. Most state emissions stations will fail you if you have pass codes stored; so if you plan to have an emissions test performed after clearing the codes this way, make sure you wait at least a few days and drive the Chevy as much as possible in that time span."

Hmm...I'm sure Holden/Chevrolet would have some sort of OBD2 port access via software to delete/switch the codes off. Either that, or there must be some manual method of resetting it via the trip meter control stalk somehow.

Yes, it has OBD2 port for sure but it requires special equipment and software that is expensive. I also suspect there is some funky combination of buttons (like ctrl+alt+del :-) to reset but so far I am unable to find it anywhere. :-(

on your steering stock is a button says MENU press it. it will show you oil life percentage. then hold down the button on the very end of the stock until it resets saying oil life at 100%. then drive your cruze for a minute and turn it off for 5 mins restart and the code 84 and engine light will go off.

Sometimes Error 82, 84, etc. appears in almost new Cruze with low mileage. Error indicator often operates wrongly in this car, so if you feel your car's working properly you should clear an error list first.
There are two ways to clear the error list:
1. You should visit your authorized service centre so they could make computer testing and remove all errors.
2. You should remove contact from battery for a while. As Calpazan said it should be around 1 hour, however in my case ~20 minutes were enough. Actually in this way you may solve many malfunctions of car's electronics. At least this action wont make harm to your vehicle so i think this is a best solution which may be of first priority...

Could be several things , compression failure , ignition failure , injection , air , ....

The only thing that You can do is to try a complete ECM reset by disconnecting the battery for an hour or so .
Reconnect the battery and drive ... if the code 84 shows back up than is it really time for expert to look at it.

Reset codes by switching on ignition and press accelerator 3 times in short succession. The codes should disappear from the display. If there is something wrong with the car (assuming the code is displayed for no apparent reason) the code will reappear.
