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 Warranty accounting instructions Warranty type Service number Damage code INTERNAL 110 or 910 45 30 00 40 Time to conduct initial diagnosis Labour operation code 45 30 01 00 (Use 99 index until 29/9/22) Time 50 TU’s Time to replace the ESC unit - J104 - New Flying Spur Labour operation code 45 30 55 50 Time 10 TU’s Time to remove and install the ESC unit - J104 - New Flying Spur Labour operation code 45 30 19 10 Time 140 TU’s Time to code the new ESC unit - J104 - to the vehicle New continental GT/C (All M/Y) Labour operation code 01 50 00 00 Time 10 TU’s Time to remove and install the ESC unit - J104 - New continental GT/C (18 M/Y) Labour operation code 45 30 19 00 Time 270 TU’s Time to remove and install the ESC unit - J104 - New continental GT/C (19 M/Y onwards) Labour operation code 45 30 19 10 Time 140 TU’s Road test Labour operation code 01 21 00 00 Time 50 TU’s (Maximum of two road tests) Parts information Refer to the ETKA parts catalogue NOTE: Permission must be given by Product Support via the open DISS query before ESC unit - J104 is replaced INTERNAL
