Hi..hope all is well.
Today had two things done ..
* Throttle Body Cleaned
*New left brake light bulb.
Drove home contently some but some 10 miles later a lot of lights on dashboard lit up..
*Cruise control not permitted..HDC not accessable (or something like that)..
Transmission Fault 1..Brake..Triangle and image of car with arrows circling car on left panel..Suspension Height something or other..and wont raise or lower.

I thought to myself last time I had a weird issue where car would not get out of 1st gear and suspension height froze it was the wrong brake light bulb and one tire was way off.
So I thought did they again put in wrong bulb??
I looked and instead of the Sylvania 7528 they had a Wagner 17916.
Went to Autozone got Sylvania 7528 that were in there before and put it in.
Still same codes.
Before these two jobs car running great but as warm weather just came in car was shutting off when AC kicked in when standing still or going really slow.
What do you guys think : (
Many thanks

 

Low battery or bad earth can give those errors, or maybe after the globe change you need to clear the codes.

 

Has you brake light switch ever been replaced? Those can cause the same symptoms. If you can clear the codes, it might help to see when (if) the behavior returns and if it is linked to using the brakes.

 

Hi...Repair shop just changed Brake light switch..all the warning lights still on and won't clear. Help.
They can't help and said must go to the Land Rover dealer..
All was well untill yesterday when they put in wrong brake light bulb ( which Ive since changed) and did Trottle neck cleaning.

 

Did they try pulling codes? If so what were they?

Did you try disconnecting the battery and touching the two cables (not attached to the battery!) together to do a "hard" reset?

 

WHAT is your battery voltage when car is off?

WHAT is your voltage when car is on?

and more useful questions for my thousandth post.

 

+Did Hard Reset as suggested..but no change.
+Voltage running is 14V..when not running 13.6V.
When Brake pedal is depressed all is normal, car obeying commands( Up..down.)..but once brake is retracted..car drops.
What can it be.

 

the brake switch needs to be non molested before install. The plunger should not be depressed or touched straight out of the box. then it should be installed with the pedal in the resting position, no adjustment or shenanigans. The shop might have installed incorrectly.

If you are near so cal, I can diagnose for you.

 

Hi..thanks ( I'm in NJ.)
*More info:
The neighbor took the Brake Light switch off so it's just dangling under there now..
with that off and Car set to the Gravel Setting it now goes to normal height and drives almost normally so I don't have to get it towed.
What can it be..computer module that has to do with brake light switch..?.. compressor?
It was result of Throttle body cleaning and install of the wrong brake light bulb.

 

Did you by chance have rain recently? It almost sounds like the wiring at the transfer case module got wet or has been getting wet and corroded.

Its the silver module behind the battery
