Greetings,

I've been lurking for a while and have searched (IMO) to no avail.

Nutshell, sporadic issues regarding starting.

Battery tests OK.

Reprogrammed BCM as per how-to.

However, sometimes, absolutely no power is available for system to start or even display any dash information. Essentially, everything, including remote entry elicits no response.

Strangely enough, the "lights eventually come on" when some other electrically connected component (gear shift, seat positioner, etc...) is manipulated, resulting in power to the system for a start.

Of course, aftermarket radio needs to be reprogrammed as to the time and I no longer receive a chirp when the initial unlock door button is pressed.

Any thoughts/insite into this matter would be greatly appreciated.

Regards,

Dave

 

battery test is ok, but did u check the battery cable and ground. for possible shorts?

 

I would recommend ringing your electrical system out. Use a meter and do a continuity test ( should have a "))))" symbol). Starting at your battery check ground to frame, positive to positive on fuse block, and basically work your way back doing a point to point test on what should electrically be connected (not testing + to -). You can also use your meter to check your fuses, I like to put one probe on the line side and run the other down the load side of every fuse instead of trying to visually see if a fuse is blown.

 

I finally figured it out!

While things were working, all tests showed that there were no problems.

Upon the advice of an acquaintance, I waited until everything failed to work and re-ran all electrical tests, only to find that NO power was available from the battery.

Nutshell...

My wife had the battery replaced (side-post) several months ago.

The "installation tech" over torqued the connection to one of the terminals of the battery, essentially loosening the battery post itself (from the battery) and not the connection between the cables and battery.

The battery was replaced free of charge and the cables were re-attached, paying strict attention to manufacturers torque specs., and voila, ALL IS WELL!

So, don't let inexperienced kiddies at Wally World install your battery?

 

Congrats on finding the problem, and being an easy fix to boot.
