i got this error today.... WHAT DO I DO!? P1684 Driver 5 Line 4

 

your 5th driver is calling on line 4

no, jk!

you disconnected the batt in the last 50 starts is all it means

 

No it doesn't.

We don't know what the code is. Some people generate the code and it means nothing more than having a check engine light.

Others have huge mechanical failure.

Join the club.

 

it went away hahahahaha

 

it will go away then come back outta nowhere one day randomly in the future while your on the freeway 40 miles from home and scare the crap out of you. it just pops up whenever something else goes wrong i swear.

 

some people said it was an error in the code discriptions on the site (because that's a GM description or w/e) and it ment that the batt was disconnected within the last 50 starts....

 

mines been on for a year and a half...knock on wood...no probs...

 

Possible causes for throwing the P1684:[*]BATTERY WAS DISCONNECTED[*]PCM WAS REPLACED OR DISCONNECTED[*]QUICK LEARN WAS PERFORMED[*]FUSED B+ CIRCUIT TO TCM OPEN[*]GROUND CIRCUIT OPEN[*]INTERMITTENT WIRING AND CONNECTORS

Either way the code has to do with the computer and output circuits...

 

Call me dumb or lame, but I actually lol'd at that.

HEHE.

But yeah, it comes up at random for no reason sometimes... Nothing to be alarmed about.

 

The factory diag sheet for P1684 is for battery disconnect. The code is from the TCM. Thats the same on all 2002 thru 2005 neons and PT Cruiser thru 2007.
