How to Install Steering Column Grounds for Aston Martin DB11

On certain AstonDB11 vehicles an electrostatic discharge (ESD), when combined with a damaged steering column control module clock spring and an insufficient grounding of the steering column upper, may lead to an inadvertent deployment of the driver airbag, which can increase the risk of injury and a crash. This instructions show how to install a contact bridge and a contact spring to the steering column. These components will remove the static charge from the steering wheel.To correct this problem you must install two grounding components to the steering column.

 

This Workshop Procedure has two parts: [where applicable]

  • Part A– Examine steering column
  • Part B– Install steering column grounds

 

Part A – Examine steering column

Note: Part A of the procedure that follows is for vehicles from L02866 thru L03917 only.

1.Move the hush panel to get access to the screw that attaches the lower duct to the instrument panel.

4.Do a check of the component number on the label

  • If the steering column is Q01 or Q02,photograph the label and do Part B after PartA is complete.
  • If the steering column is Q03 or higher, nomore work is necessary after Part A iscomplete.

Part B – Install steering column grounds

Note: Part B of the procedure that follows is for all DB11 vehicles to L02865. Part B is also for DB11 vehicles from L02866 thru L03917 with Q01 or Q02 steering columns.

1.Move the steering column to its lowest position.

2.Remove the top and bottom shroud assembly for the steering column (refer to Workshop Manual Procedure 11.04.DB).

3.Install the contact spring onto the circular casting on steering column

5.Install the contact bridge onto the steering column

Note: The contact bridge must touch the outer steering column shaft.

6.Use a multi-meter to measure the resistance between the inner column (1) and the steering column casing (2)

  • If the resistance is below 3 ohms go to step 7.
  • If the resistance is above 3 ohms, make sure thecomponents installed in steps 3 thru 5 are installed correctly.

Note: If the resistance is still above 3 ohms, contact AMTech.
