Technical product information
Repeated traction control interventions experienced upon reaching 30km/h

Transaction No.: 2067579/2
Release date: 04-Nov-2022

Customer statement / workshop findings
Repeated traction control interventions experienced upon reaching 30km/h (Figure 1)
HINT: Refer to the video which has been uploaded onto the Bentley Hub reference Video 1 for TPI 2057579

Figure 1

Technical background
In the event the issue is as exactly as described, refer to the instructions within the Measure section

Production change
Not applicable

Measure
VERY IMPORTANT:
1) Confirm the tyre pressures (all tyres) are to Bentley specification
•

Check to confirm the wheel and tyres assemblies are Bentley approved (same specification parts as per the original factory build

Or
approved Bentley accessory wheels and tyres are fitted
•

Confirm the ‘B’ marking is evident on all tyres (Figure 2)

Figure 2
2) In the event the issue is evident following a tyre and/or wheel change, perform an inspection of the relevant vehicle corner, check each of the
following sensors for contamination damage etc
•

Upright acceleration sensor

INTERNAL

•

ABS wheel speed sensor

•

Referring to the applicable wiring diagram - Conduct a wiring integrity check of each sensor and check all associated wiring
harnesses/connectors etc for damage

3) In the event the wheels and tyres and sensor/wiring checks are within specification - Check the applicable vehicle corner wheel bearing for
any noise, excess movement or contamination
4) With the aid of a second operative, perform a road test to monitor the following measured values
HINT: Refer to the video which has been uploaded onto the Bentley Hub reference Video 2 for TPI 2057579
DO NOT UNDER ANY CIRCUMSTANCES PERFORM THIS OPERATION WITHOUT A SECOND OPERATIVE
•

Record a video showing live values (see example in Figure 3 of the values which should be monitored) whilst the fault is present

TIP: Save a copy of the video

Figure 3
5) Conduct a second road test (Reference Manoeuvres road test below) as per the instructions below, the operative MUST confirm if the fault
remains during the second road test (Manoeuvres)
Manoeuvres road test
With appropriate space and ensuring all speed restrictions are adhered to, conduct the following where safe to do so:
1) Switch off the engine and lock the vehicle for 10 minutes
2) Unlock the vehicle
3) Switch ON the ignition and start the engine
•

Select Bentley mode and select Drive (D)

4) Whilst attempting not to induce a traction control intervention, drive the car in a straight line for approximately 10 seconds at a minimum of
50kph
•

Reset the traction control by lifting off the accelerator, allow the vehicle to come to a gradual rest (where safe to do so)

•

Switch off the engine

5) Switch ON the ignition and start the engine
•

Select Bentley mode and select Drive (D)

6) As per normal customer usage, drive off in a straight line only ensuring the following separate throttle inputs (a to c) until either the
30kph intervention event or approximately 50kph (ensuring all speed limits are adhered to)
a) Apply enough throttle input to smoothly manoeuvre off from stand still at a rate of approximately 5kph/second
Reset the traction control by lifting off the accelerator, allow the vehicle to come to a gradual rest (where safe to do so)
b) Apply enough throttle input to smoothly manoeuvre off from stand still at a rate of approximately 10kph/second
Reset the traction control by lifting off the accelerator, allow the vehicle to come to a gradual rest (where safe to do so)
c) In swift succession, smoothly manoeuvre off from stand still at a rate of approximately 10kph/second and lift of the throttle if traction control
intervention occurs, then swiftly reapply throttle as per the previous 10kph/second input
Reset the traction control by lifting off the accelerator, allow the vehicle to come to a gradual rest (where safe to do so)

INTERNAL

After conducting points a to c Is the traction control invention still present?
Comments

7) Switch OFF the ignition and stop the engine
•

Apply the steering lock

8) Switch ON the ignition and start the engine
•

Select Bentley mode and select Drive (D)

9) As per normal customer usage, drive off ensuring the vehicle is driven via junction exits and performing small radius cornering
ensuring the following separate throttle inputs are conducted (d to f ) until either the 30kph intervention event is evident or approximately 50kph
is achieved
d) Apply enough throttle to smoothly manoeuvre off from stand still at a rate of approximately 5kph/second
Reset the traction control by lifting off the accelerator, allow the vehicle to come to a gradual rest (where safe to do so)
e) Apply enough throttle input to smoothly manoeuvre off from stand still at a rate of approximately 10kph/second
Reset the traction control by lifting off the accelerator, allow the vehicle to come to a gradual rest (where safe to do so)
f ) In swift succession, smoothly manoeuvre off from stand still at a rate of approximately 10kph/second and lift of the throttle if intervention
occurs, then swiftly reapply throttle as previous 10kph/second input
Reset the traction control by lifting off the accelerator, allow the vehicle to come to a gradual rest (where safe to do so)
After conducting points d to f Is the traction control invention still present?
Comments

On completion of the Manoeuvres, conduct the following:
10) With the ignition off - Referring to Rep.Gr 45 - disconnect the electrical connection from the ESC unit -J104 and wait 10 seconds - Reconnect
the electrical connection
•

Erase all applicable DTC’s in particular any DTC’s relating to 03 Brakes

•

Perform a subsequent road test recording the same values as (Figure 3) to establish if issue has been rectified.

VERY IMPORTANT: If fault is still evident remains present - Open a new DISS query or respond via the already open query,
ensuring all previously requested information is clearly attached, DO NOT conduct any further repair work until permission is granted from
Product Support
•

Provide clear information regarding when the fault occurs, For example after engine start, up to a speed of 28 km/h

In the event that Product support grant permission to replace ESC unit - J104 via the open DISS query
The operative must ensure the manoeuvres road test is repeated after ESC unit - J104 renewal to confirm the resolution of the
concern
