Checking Cruise Control using Measuring Values

Cruise Control Activation

DBW (Drive-by-Wire)

The CCS (Cruise Control System) activation in DBW (Drive-by-Wire) throttle systems will vary depending on the Engine Control Module.

1) Control modules using Short Coding often use a Login code and the letter "G" is shown in the component field when activated.

1.8T Gasoline example:

Address 01: Engine        Labels: 06A-906-032-AWP.lbl
  Part No: 06A 906 032 LP
  Component: 1.8L R4/5VT     G   0005
  Coding: 07500

1.9 CR TDI example:

Address 01: Engine (CBE)       Labels: 03L-906-022-CBE.clb
  Part No SW: 03L 997 016 N    HW: 03L 906 022 J
  Component: R4 2,0L EDC G000SG  8680  
  Coding: 0050072

Activating Cruise Control on a new (DBW) ECU using Login

DBW (Drive-by-Wire) Factory fresh ECU's often come with cruise control de-activated.

[Select]
[01 - Engine]
[Login - 11] or if that function is not available then use [Coding - 11] instead
Enter 11463 to activate cruise control
[Do It!]

Notes:

• You may have to cycle the key off and back on before the CCS is activated and the letter "G" is shown in the component field.
  
• The Throttle Body Alignment (TBA) may need to be completed before CCS operates.
• Adaptive Cruise Control (ACC) uses the letter A instead of G in the component field.
• If the incorrect Cruise Control type is activated it will be necessary to deactivate it using the Login of 16167 followed by a key cycle and enabling the proper type.

2) Control modules using Long Coding are activated in the Coding. Due to different Control Modules Vehicle Equipment, the actual Coding Table is not shown here but will automatically be used by the Long Coding Helper with VCDS.

Address 01: Engine (CBF)       Labels: 06J-907-115-CBF.clb
  Part No SW: 1K0 907 115 AL    HW: 1K0 907 115 AK
  Component: 2.0l R4/4V TFSI     0030
  Revision: E3H21---    Serial number:
  Coding: 040301081C070160

Activating Cruise Control on a new (DBW) ECU using Long Coding

[Select]
[01 - Engine]
[Coding - 07]
[Long Coding Helper]
Check the box for CCS and Exit
[Do It!]

Note:

• You may have to cycle the key off and back on before the CCS is activated and the new coding takes effect.
  
• The Throttle Body Alignment (TBA) may need to be completed before CCS operates.
• Long Coded modules do Not have the letter G in the component field. If you wanted to see if CCS is enabled, use the Long Coding Helper and see if the box is checked.

DBC (Drive-By-Cable)

The CCS (Cruise Control System) on DBC (Drive By Cable) throttle systems may or may Not be controlled by the Engine Control Module. Refer to the factory repair manual for additional details on these older systems.

Checking Cruise Control using Measuring Blocks

Checking CCS using Measuring Blocks normally involves evaluating binary values of related switches.

Gasoline Engines

Gasoline Engines often use Measuring Block group 066 to display CCS info. Refer to the charts below using line Field 2 and 4 data.

Diesel Engines

Diesel Engines often use Measuring Block group 006 to display CCS info. Refer to the charts below using line Field 2 and 4 data.

Field 2 Data

0	0	0	0	1	0	0	0	0 = Brake Not Depressed	1 = Brake depressed (brake light switch)
								0 = Brake Not Depressed	1 = Brake depressed (brake pedal switch)
								0 = Clutch Not Depressed	1 = Clutch Depressed (always 0 in Auto. Trans.)
								0 = CCS Not active in ECM	1 = CCS active in ECM
								N/A	N/A
								0 = CCS Switched Off TDI only *	1 = CCS Switched On TDI only *
								0 = Accel. pedal overide	1 = CCS Operating
								0 = Normal CCS	1 = Accel. pedal overide

Field 4 Data

0	0	0	0	0	0	1	1	0 = CCS Switched Off	1 = CCS Switched On
								0 = Cancel/Off Activated	1 = CCS Switched On
								0 = SET/ Decel. Not Pressed	1 = SET/ Decel. Button Pressed
								0 = Resume/Accel Not Pressed	1 = Resume/Accel Button Pressed
								N/A	N/A
								N/A	N/A
								N/A	N/A
								N/A	N/A

Special Notes

• When additional information is available in VCDS the binary values will appear in a balloon while connected to the vehicle. If there is a discrepancy with the details in the charts above, use the engine specific data in VCDS.
  

• On some vehicles equipped with an Automatic Transmission it may be necessary to test drive exceeding a speed of 30 km/h (19 mph) before voltage is supplied to the CCS switch.
  

• Some of the newer Engine Control Modules may use the UDS/ODX/ASAM protocols. Those modules do not support conventional Measuring Block Groups. Advanced Measuring Values will be used instead and you will check the boxes for CCS (or similar) to locate and view the readings.
  

• On vehicles with additional equipment, the [16] - Steering Wheel Electronics module may display additional signals.
  • See the Cruise Control Retrofitting and Diagnostic Procedures for the specific platform.
    

• If factory equipped CCS decides to stop working for no apparent reason in a 2011-2012 Jetta or Beetle with a 2.5L Gas engine make sure the letter G isn't missing from the Component field. For some reason we've received numerous reports like that from NAR market (US/Canadian) cars without any damage/repair history that would explain lost CCS. Simply turning it off and back on again via Login with key cycles in between has resolved all issues to date.
