LED turn signal damage.

NZ.Z

Hi all,

I recently changed the turn signal bulbs to LED and used resistors to prevent the hyper flash.
Yesterday I was told by an auto electrician that Nissan use a Body Control Module to control all of the electrics and that the resistors could quite easily fry the module which would then cost $1500 - $1600 to replace.
He said that this could happen at anytime, a week, 4 months a year or years after fitment.
I've never heard of it happening before but was wondering how true it is and why it does it?

Could anyone shed any light on this?

The resistors provide equivalent load to the standard light bulbs. It also gets warm in the process since it's trying to dissipate the power as heat. You'll risk damage to the BCM due to faulty connection or too low of load resistance (e.g., short between the terminals).

You can measure the resistance of the light bulbs using a meter, and then make sure the load resistor value is not less than the bulb resistance.
