#1

I have a 1994 Jeep Grand Cherokee with 194,000 miles. When I apply the brakes, the vehicle information center states “rear lamp failure” even though the lamps are working. (I back up towards shop windows a lot) Should I try replacing the unit?


#2

I wouldn’t. The probably expense in replacement probably isn’t worth it. I can check my rear lamps manually, possibly with more frequency, and do just fine.


#3

Just keep driving it.

The wife’s got a 90 Cherokee I’m try to keep alive.

Got a welder?

Tester


#4

No tester but was thinking since it was a recycle center unit to replace one that didn’t work at all, maybe try another one. Not expensive, just a pain to replace.

Your lights are working, but does one seem dimmer than the others? I had a similar situation with my '88 Toyota. The problem was corrosion on the contacts in the light socket causing increased resistance that made the bulb monitor think a bulb blew. I cleaned it up, gooped it good with dielectric grease (bulb grease), and haven’t had the problem return for almost two years. year.


#6

They both look normal but i’ll try that and see what happens.


#7

Did you replace just one of them recently? A difference in maker of the bulb could explain a variance in resistance that may also be fooling the sensor. Bulbs usually come in a two pack, so take the other and replace the old bulb on the other side. See if that also works.


#8

I always replace bulbs in pairs.
