2001 S80 T6 "Bulb Failure Position Indicator"

[mvsuzr]

First got this message a couple of days ago when I started the car. Not a big deal, but I checked all the lights and everything was on.
(Off the topic, love to get the headlights to stay off!)
I'm sure it's probably a resistance issue kicking a false alarm, but I don't feel like pulling all the bulbs out.
The big problem is that I just don't know what Volvo calls a "position indicator"
Nothing in the owners manual (not surprising), and I'm still downloading the VADIS software, seems like that's going to take another day or so.

Any ideas?

It's one of the "parking/tail" lights. Sometimes they burn out - other times the connections corrode and resistance builds up at the base of the bulb. Rarely the socket will crack causing a loose connection. Here's how to change them out:

Front parking light/direction indicator

· Switch off the ignition.
· Open the hood.
· Press down the retaining catch with a screwdriver and pull out the lamp housing.
· Press the retaining spring downward and pull the connector out of the lamp housing.
· Turn the bulb holder counterclockwise and remove it.
· Remove the defective bulb from the holder by first pressing it in slightly and then turning it counterclockwise.
· Install a new bulb in the holder and reinsert
the bulb and holder in the lamp housing.

· Press the connector onto the bulb holder.
· Switch on the ignition to test the bulb.
· Press the lamp housing back into place on the fender. Be sure it seats properly.


Tail lights

1. Brake light
2. Back-up light
3. Direction indicator
4/5. Tail lights
6. Fog light (left side only)


All tail light bulbs are accessed from inside the trunk.
· Switch off the ignition and open the trunk.
· Fold the covering panel inward to access the bulbs. When replacing right tail light bulbs, access is made easier if you pull out the cargo net in the trunk completely before folding down the panel.

The bulbs are located in two separate holders, an upper and a lower one. Each holder has a retaining catch.

To replace a bulb in the upper holder:

· Disconnect the wiring from the bulb holder.
· Press the retaining catch upward to release the lower part of the holder.
· Press the retaining catch downward to release the upper part of the holder.
· Replace the defective bulb.
· Press the bulb holder back into place.
· Reconnect the wiring.
· Fold up and close the covering panel.

To replace a bulb in the lower holder:

· Disconnect the wiring from the bulb holder.
· Press the retaining catch toward the outside of the car to release the holder.
· Replace the defective bulb.
· Press the bulb holder back into place.
· Reconnect the wiring.
· Fold up and close the covering panel.

Thanks for the detailed response!

I'll be checking this out in the next few days (snow's melting...)

Thanks again for the info.

Turned out to be the left tail light, one of the bulbs quit working just as I settled in to work on it.

One #67 bulb later, no more alarms.

By the way, the IPD web site recommends replacing lights in pairs, they mention that sometimes the difference in resistance between a new and an old bulb will retrigger the alarm.

I've only changed the ones that were burned out and never had a subsequent problem.
