I had the car plugged in this morning and loads of fault codes were present so i had them all wiped and the warning light stayed on. Is this the the head light switch assembly? Inspect the bulbs and sockets, be sure there are no burned connection or melted wires. I was wondering if the brake switch could somehow throw the transmission into limp mode. Remove the panel directly above the driver's side foot well. If not, work your way up circuit, to locate short.
I see how removing the seat can add a little more room when trying to crawl under the dash. Got my codes read today, and the person who read it thinks that it is the abs module or speed senors. Lying on your back and getting both your arms under there - 10++! Need to buy parts for this project? May 5, 2013 Followup from the Pelican Staff: Thanks for the information. They can figure out what part or repair kit you need. Also, yep: It does take a bit of effort to squeeze the old light switch from the metal bracket. This afternoon I put all that knowledge to work. I have a 98 323is and they didnt show stock, but they found one under a different model,same exact switch.
Thank you again for this, Nick! You should see the reflection off of the wall when you step on the brakes - if you don't, then your switch is probably shot. As it makes contact, the brake light switch will automatically adjust to correct position. When the pedal is depressed, the switch closes the contacts and activates the brake lights. It only goes into limp mode when I take my foot off the brake in park. July 31, 2013 Followup from the Pelican Staff: Thanks for the additional information.
October 30, 2017 Followup from the Pelican Staff: See this: - Nick at Pelican Parts tmb14 Comments: I have an E46 2002 325i and all three stop lamps come on when the ignition switch is on with 3 second delay. Comments and Suggestions: machinebaby Comments: Tried breaking the switch, ended up bending the bracket. Make sure car is on a levelsurface - remove panel belowsteering column - climb under dash,upside down - depress brake pedal - remove wiring harnessfrom switch - break off the red tabor the entire white button - remove switch from itsbracket - pop in the new switch - depress the red tab onthe switch to lock it into place - connect wiring harness - reinstall panel underthe steering column You are done. The way to remove the brake switch without breaking it is to first depress the brake pedal. You don't have enough travel to pullout the red cylinder for the taps to retract the taps to get the switch out from the bracket. I used a scrap board and wedged it against the seat mount.
So I snipped it and spliced it. Wouldnt trust a person who says to break something for obvious reasons. Maybe this cable should plug to the gear circuit to Decelerate when i use brake?? What fault codes are stored? See if it looks like it is misaligned, that may indicate it is bent from replacing the switch. Both lights are not working, and the one on the passenger side is on all the time even though I'm not using the brake. I squeezed it and it popped loose. December 17, 2013 Followup from the Pelican Staff: Thanks for the input on this one.
Does the instrument panel display Park when in park, and are all other gears displayed correctly? June 4, 2013 Followup from the Pelican Staff: Thanks for the feedback. Once the sleeve is all the way out you can squeeze the locking tabs and the switch pops right out. . As always, if you have any questions or comments about this helpful article, please Reader Feedback: At the end, you instruct the readers to rip the switch out of the bracket. I would check the vehicle for fault codes to start. September 14, 2014 Followup from the Pelican Staff: Yes, you will need to connect the spoiler brake light.
We do the procedure for reset but dissapears and come again. It may take longer, depending on how easy it is foryou to get around under the dash. Start at the switch, does it get triggered when it shouldn't? Just a note, the three screws holding the panel in place are all different: 1 The shiny screws goes in the hole in the bottom 2 The long black screw goes in the top-right hole 3 The shorter black screw goes in the top-left hole I think I spent more time looking for the screw I dropped than actually replacing the switch. If it is faulty it can cause the brake lights to malfunction. You have two possible solutions.
August 19, 2014 Followup from the Pelican Staff: If you add fused power to the brake light switch, do they brake lights work? This is the 2 pin switch. A drop in voltage and the car can act odd and throw that light along with other things. Thanks for the great instruction and comments. I replaced the brake light switch, no change. I finally decided to change the stop light switch, even though all three lights worked. I was surprised how much force it took.
June 15, 2017 Followup from the Pelican Staff: Thanks for the additional info and feedback. Baffled as too wat wud b different with ignition on or running to wen it's in position 1??? March 10, 2013 Followup from the Pelican Staff: Thanks for the reminder. I am not sure if you can replace that solenoid separately, or if you need to purchase a new valve body. Recycle parts, packaging and fluids when possible. To finish the job, simply install the new switch into place, and reconnect the wire harness. Grin and bear it : 2.
I did not see one. Remember that circuit will not show any current until it's energized by pushing on the brake pedal. I am able to accelerate and go up hills just as easily as before it came on. If you had time for any suggestions, much appreciated. Btw, cruise control was not working when the transmission light was on. It was held by a one 10mm bolt. Test the signal out of the switch to see if it is on all the time.
