My friend’s MY88 car finally left my shop today after two to three months of work but there two faults still showing on the dash.

One is a bulb failure warning. I have made sure all of the external lights are working but still the bulb failure module is illuminated. Now I did replace the rear bulbs in the taillights (reverse, turnsignal, brake, and running) with colored LED lamps so I am wondering if the bulb failure modules are not getting the right signal from the LED bulbs. Has anyone else made this switch and been able to correct for the difference in the bulbs?

BTW, the rear lamps are MUCH brighter with the LED bulbs installed verses the original standard incandescent 1156 bulbs and I believe they run much cooler than the original bulbs as well.

Second fault registering on the dash is a low pad alert. One front pad sensor wire is not actually attached to the caliper and is just hanging loose inside the engine bay. It has a jumper installed across the contacts but still the low pad alert is registering on the dash. Are these low pad sensors that fit into the brake pads still available?

 

Lots of info about using resistors alongside LED's on the various Jaguar forums.

I think Don made a post about them here just a day or so ago re: the BFM not seeing the LED resistance high enough to pass the BFM check.
From what I've heard, you can't run LED's without a resistor and the resistors can get HOT.

Someone over on the jag-lovers forum suggested these:

Load Resistors 6-Ohm Fix Turn Signal Light Hyper Flash Blink LED Bulbs Lamps

And yes, the ebay listing descriptive text suggests mounting these to metal to allow them to act as heat sinks.
If I did that at least it would be outside the plastic taillight housings d=so the heat would not have any effect on those.
I still think the LED bulb conversion is a good thing.

 

i confirm, led will mess module and will flash error on dash, i've tried them but i prefer warm light of incandescent bulb. as for pad sensor, just recheck the jumper and other three of them pads/jumpers/whatever you've got there perhaps one is missing
