Gear selector - warning and fault code - gear knob switch resistance high (SC12/02)
Notes
Transaction No.: 2028014/2
Repair instructions
Technical background
A warning may be displayed in the driver’s instrument panel that reads Selector lever: System fault You can change gears, this warning will be
accompanied by fault code P17EC00, recorded in module 81-Selector lever sensors control unit UDS
The cause has been attributed to the four pin electrical connection between the gear knob and the gear selector shaft that forms part of the gearshift
interlock. The relative movement produced between these two parts both from the drivers hand and from vehicle resonance can, in severe cases,
result in a degradation of the terminals contact area. The subsequent out of specification resistance will result in this code being logged and the
warning displayed
Remedy
The vehicles detailed in the applicability section above require the application of a conductive enhancer to the four electrical connector pins located
inside the gear knob
The conductive enhancer to be used is named Stabilant 22 which should be mixed, 4:1, with 99% Isopropanol or pure Ethanol the Stabilant 22 can
also be applied neat. Only 99% Isopropanol or pure Ethanol must be used when mixing the Stabilant 22 mixture.
Customer notification
Customers do not need to be informed directly of this campaign. Please ensure that all affected vehicles are checked and repaired during a service
visit. You should also inform your new and used car sales departments so that the vehicles affected can be checked and, if necessary, repaired
immediately (and not just before sale)

Check
If the vehicle is not already listed as repaired in the ‘’Repair history’’ (in ElsaPro), check the vehicle for the campaign identification mark, (see Figure 4),
if this is not visible carry out the required work in accordance with these instructions
Parts
The required replacement parts should be ordered from Bentley Motors Limited Crewe or through your regional Bentley parts distribution centre.
Work
If a fault of this nature has already been reported on a vehicle in the applicable section then this vehicle should have Stabilant applied to a new gear
knob and that new part fitted to the vehicle. For all other vehicles in this campaign apply the Stabilant to the original gear knob
Important: When using Stabilant 22 and 99% Isopropanol or pure Ethanol be advised
to wear eye protection and adhere to all health and safety guidelines.
Figure 2
1. Remove the gear knob. Slide the collar (1) downwards then pull off the gear selector knob (see Figure 2)
2. Prepare the Stabilant
‒
The Stabilant 22 kit (WT10224) includes 5ml of Stabilant 22 concentrate, an empty 15ml mixing bottle, application brushes, and
manufacturers mixing instructions. The Stabilant 22 should be mixed by following the manufacturers mixing instructions.
‒
Note: Should Isopropanol or Ethanol not be available, Stabilant 22 can be used neat straight from the 5ml bottle, but use sparingly by
applying only a thin coating ensuring an even and complete covering on the connections
‒
‒
Figure 3
3. With the gear knob removed and away from the vehicle invert the knob to apply the Stabilant (see Figure 3)
‒
Apply the mixed Stabilant 22A or 22E to the electrical pins located inside the gear knob. Use the application brush supplied in the kit, or a
new clean cotton bud to apply a thin coating of Stabilant 22A/22E to each of the four connections. Ensure the pins are evenly and
completely coated
‒
Allow approximately 2-3 minutes for Isopropanol/Ethanol to evaporate, which will leave a thin layer of Stabilant 22 on the connections
4. Apply yellow campaign completion mark to the base of the gear knob (see Figure 4)
5. Refit the gear knob ensuring a positive click as it engages with the selector shaft. Refit the collar, again a positive click is indicative of correct
engagement
6. Clear any related fault codes and check the gear selector interlock function for correct operation

On completion apply a yellow campaign completion mark to the underside of the gear knob
