2002 Grand Caravan Sport 3.3

I have no reverse lights. The bulbs are OK, I tested for voltage at the sockets and they are not getting power.
I looked for a fuse in the under hood panel but there is not one labled for it. I tested them all and they are good.
What say you guys?
Where is the switch?

 

I pulled both battery cables and the fuse for 5 minutes and I have Reverse Lights again!

I love my reverse lamps. These are no BS low quality LED's. They are CREE elements. I tried the halogens and other than not as bright, they were short lived.
I missed these immediately the fist time I reversed without them. I back in everywhere I go. Even in daylight folks will comment and ask about them.

Thanks to "user97" over at the Chysler Boards!

 

Why did pulling the batt cables/fuse fix the issue you were having?

 

Just as turning your home computer off then back on to cure some ills it may have, disconnecting the battery or pulling the IOD fuse does the same for your vans computer modules. In this case the the PCI data bus controlled by the BCM and/or the FCM that controls headlights.

 

So the BCM is controlling the reverse lights then? Based on the symptoms I was leaning more towards a switch

 

The front control module is the output for the lights. He reset the FCM when he did the disconnect. It will probably happen again.


It's usually the headlamps that quit working on those..hmm.

 

That's interesting. That vintage van should have had incandescent blubs for reverse shouldn't it? If he put LEDs in, couldn't that be making things cranky potentially?

 

Hope not, they have been in there for years. Those are decent units, They are not the kind that need a resistor to keep the turn signals from flashing too fast.

 

That's what I was thinking of where you have to add a resistor to make things work right.

 

Also for years now I have been running the European Voyager dual element head lamps that are powered by a custom independent harness and solenoids all triggered by the high and low beam signals of the OE harness.
