Solving SRS Light Problems for a D2

SRS Light (Safety Restraint System)

The SRS light comes on when there is a short in one of the connections from the DCU to one of the SRS components.

Diagnosing the truck will cost you around $120 at a Land Rover dealership of you might be able to find a indie LR shop that will do it for free or on the cheap. The testing equipment is expensive and not only brand but model specific. Some scanners can read a D2 DCU but not a D1 DCU.

WARNING: before you do any work on the SRS system you must disconnect the battery and let the truck sit for 10 minutes. Most items related to the SRS system are pyrotechnic and will explode and can cause serious enjury or death if proper precaution is not taken.

What sets off the SRS light? It can be something as simple as dust in the seat belt sensor. Try connecting and disconnecting the passengar side seat belt 20 or 30 times in a row with the truck running. Then restart the truck. If that doesn't work then try going to an empty parking lot turning the wheel all the way in one direction then start driving and just let the wheel work its way back to center. If you hear any unusual whining or other sound coming from the steering wheel it is the driver side airbag module that needs replacement. Another common problem is a short at the ground of either the driver side of passengar side seat belt pre-tensioner (where the seat belt clicks into). Check the bolt that holds the pre-tensioners in place. Loosen it and try tightening it down again. This is an eletrical ground for the pre-tensioner.

If you get a diagnostic it will tell you exactly what the problem is. If you need a new seat belt pre-tensioner, try this first. Click and unclick the seat belt times. Sometimes dust builds up in the pre-tensioner and causes the connection to seem faulty. After re-starting the truck if the light stays on then you have two options. The best bet is to get one from the dealer new. $218. You will need your VIN. Your second option is to get one used from one of our trusted parts guys like Will Tillery or Paul Grant. Besides seat belt pre-tensioners another common problem is the airbag units themselves. These I would suggest buying the part new from Land Rover and installing it yourself. Installation is fairly easy for both. Again disconnect the battery before handling the SRS system.

Just to add onto an already well put post, if you get a code for either the passenger or drivers pretensioner there is an option between all the clicks and getting a new one. Under which ever seat you have to code for there will be a yellow connector with 2 wires, will usually be seen from the front of the seat underneath.
You can put some dielectric grease into that connector, this can be sourced from any little or big auto parts store. Just be careful not to let the grease from the 2 pins make a connection. If this doesn't work then odds are it is time for a new one.

thanks for the additional note.
