Rear lamp failure and Coolant Sensor Bad Error Message

When the message came on the console saying rear lamp failure I replaced all the light bulbs and tested them. All break lights come one when I hit the breaks, but the error message still comes on after I turn on the ignition. Same thing happened when the coolant sensor failure message came on and I replaced the coolant sensor. Any help with getting these error messages to go away would really help.

The Rear Lamp Failure light comes on, and Ii have no been able to locate where this is located. I do not have an owners manual. I have checked the tail lights, brake lights, even the tag lights, and I am...


Nice SUV, I have the same with 5.2L V8 Limited!!!

Are you sure that there are no lights out?pay attention to the third brake light because it has 3 bulbs and if one is outit will give you that message.also make sure that all of the bulbs are the right ones.

I used to get the "Rear Lamp Failure" message on my '93 Limited after the lights were on for a few minutes... it went away when I changed the rear bulbs to the same brand. The Lamp Outage Module (located in the LR quarter panel, near the fuel filler) is looking for differences in current flow between the left and right side bulbs.

You probably need a new lamp outage module...
CIRCUIT OPERATION
The Lamp Outage Module (LOM) determines if a rear lighting lamp is not operating. When the ignition switch is in the START or RUN position, circuit A1 from fuse 8 in the Power Distribution Center (PDC) connects to circuit A21. Circuit A21 feeds circuit F87 through fuse 5 in the junction block. Circuits F87 feeds the LOM.
- Circuit G46 from the LOM connects to the Vehicle Information Center (VIC) . When the LOM senses a inoperative lamp, the VIC displays the data to the vehicle operator.
- Circuit L90 which feeds the tail lamps and side marker lamps, connects to the LOM. From the LOM, circuit L90 continues to the license plate lamps. Circuits L21 and L22 from the LOM power the tail lamps and side marker lamps.
- Circuit L50 from the stop lamp switch connects to the LOM. From the LOM, circuits L73 and L74 power the stop lamps and circuit L87 powers the Center High Mounted Stop Lamps (CHMSL) . Circuit Z1 grounds the LOM.


If you need tha owners and repair manual about your ZJ Grand Cherokee, just keep in touch and send me one comment.

Hope this helps (remember to rate this answer).

2001 jaguar s type - Right tail lamp failure message.... I replaced bulbs and fuse and tail lights still don't work but the dual element right break light does illuminate when I press the break also right...


There is a harness that you unplugged for the rear tail lamp. Make sure it is fully pressed and locked. This is always the cause on jags for tail lamp failure.

I keep getting a error message in the text window - "bulb failure piosition light" There doesn't seem to be any bulb failure. Where is this position light and what do I have to do to erace this...


Position Bulb hailure is caused by the rear tail light bulbs, (the message is cryptic at best). I have had to replace my wife's 2006 xc70 about a half a dozen times. the problem I see is due to the holder the bulb sits in. It is a PAIN replace and seat properly so if there is a connectivity issue with the holder and lens assembly you'll get that message. I would typically see it when I hit a bump or stepped on the break. The message would flash intermittently and annoy me no end. Before you put the bulb\holder back in the light assembly, make sure that you apply some bulb grease and also check to make sure that the spring loaded terminals that make the electrical contact are not compressed or bent, if theat are you will continue to get the message even if you replace the bulbs, (becase the bulb was not the problem, the problem was the holder).

There is a light coming on in my 1994 toyota camry it looks like a little car with lines coming out of the back of it, what does it mean?


Hello. Please allow me to assit.

The light that you see is the 'rear taillamp failure ' indicator. This light comes on when you have a burnt out brake or taillamp. A sensor in the trunk (driver side) looks after the operation of the rear bulbs,.

When checking the rear lamps for outages, please do not forget to look at the brake light in the rear window, it too is monitored by the rear lamp failure sensor.

Replace any burned out lightbulbs, and the sensor will shut off the light.

How to reset rear light out indicator lamp


There is no "reset" for the rear lamp failure system. The light goes out automatically wehen all of the rear lamps (brake and tail) are working. Did you check the brake light in the lower part of the back window? Also note that the lamp sensor is very sensitive; it needs to see all the bulbs to be the same wattage. The wattages can vary from nfgr to mfgr. Let me know waht you find on the 3rd brake lamp in the back window.

1996 Jeep Grand Cherokee electrical problem


Check the center brake light assembly. There are 3 bulbs and if one is out it will give you the bulb out warning. This is frequently missed as if the center bulb is out it is easy to overlook.

Do yourself a favor and replace all 3 when you are there as the dissassembly/assembly is not that easy on 96-98 Grands
