"9" for address word "19" (Gateway) and enter by pressing "Q" key. Press keys "0" and "7" for "Code Control 
Module" function "7" and enter by pressing "Q" key. Enter code into CAN data bus Interface (J533). For coding 
options, see Fig. 9 . Codes from each individual control module are added together to create CAN data bus 
interface code. For example, enter 00006 if equipped with ABS and Airbag, (ABS activated 00002 + Airbag 
activated 00004 = 00006).

THROTTLE VALVE CONTROL MODULE (J338) 

Throttle Valve Control Module (TVCM - J338) teaches ECM various positions of throttle valve when ignition 
is on and engine is not running. Throttle positions are stored in the ECM. Throttle position is communicated to 
ECM through two angle sensors: Angle sensor 1 for throttle valve drive (G187) and Angle sensor 2 for throttle 
valve drive (G188). Sensors are integral parts of the TVCM (J338). Manufacturer recommends using Scan Tool 
(VAG 1551/1552 or VAS 5051/5052).  

Adapting Throttle Valve Control Module (J338) To ECM (J220) 

TVCM (J338) adaptation must be performed when voltage supply to TVCM (J338) or ECM is lost. TVCM 
(J338) adaptation occurs:  

z

Automatically if ignition is switched on for 10 seconds or more, without operating accelerator pedal or 
starter and ECM recognizes a need for adaptation. No notification that adaptation was successful will be 
given when this happens.  

z

When initiated through diagnostic function 04 - BASIC SETTING in display group 60, (VAG 1551/1552 
or VAS 5051/5052). If using generic scan tool, follow scan tool manufacturer's instructions.  

NOTE:

When adaptation of throttle valve control module is necessary and vehicle is 
equipped with A/T, the transmission control module must also be adapted. 
Perform adaptation of A/T to its Basic Setting. See A/T BASIC SETTING . 

NOTE:

Engine will not start during automatic adaptation. Ignition must remain on 
(engine off) for entire adaptation procedure. Ensure coolant temperature and 
intake air temperature are between 41-194° F (5-90° C). ECM will abort 
adaptation if; throttle valve cannot be closed completely (e.g.: dirty throttle

Generic Scan Tool 

If possible it is best to warm-up vehicle by test driving. Connect scan tool to DLC. DLC is located at left side of 
steering column. See Fig. 1 . Follow scan tool manufacturer's instructions and adapt throttle valve control 
module to ECM.  

Scan Tool VAG 1551/1552 Or VAS 5051/5052 

1. If possible it is best to warm-up vehicle by test driving. Connect scan tool to DLC. DLC is located at left 

side of steering column. See Fig. 1 .  

2. Turn ignition on, engine off. Using scan tool, retrieve DTCs. See RETRIEVING DIAGNOSTIC 

TROUBLE CODES .  

3. If DTCs are stored. Repair as necessary. See DIAGNOSTIC TROUBLE CODE IDENTIFICATION . 

If no DTCs are stored, press right arrow key. Using scan tool, clear DTC memory. See CLEARING 
DIAGNOSTIC TROUBLE CODES . After clearing codes, press right arrow key. Go to next step.  

4. Adapt Throttle Valve Control Module (J338). Press keys "0" and "1" for address word "Engine 

Electronics", and enter by pressing "Q" key. Press keys "0" and "4" for "Basic Setting", and enter by 
pressing "Q" key. Press keys "0", "6" and "0" for "Display Group 60 Basic Setting", and enter by pressing 
"Q" key.  

5. After no longer than 30 seconds, ADP. OK should appear in specification window of display field 4. If 

APD. OK appears TVCM has adapted successfully. Wait a minimum of 30 seconds before ending 
"Display Group 60 Basic Setting". To end "Display Group 60 Basic Setting" press right arrow key. Press 
keys "0" and "6" for function "End Output" and enter by pressing "Q" key.  

6. To store values, turn ignition off for at least 25 seconds (control module after-run). If APD. ERROR 

appears, TVCM has not adapted successfully. Check for DTCs. See DIAGNOSTIC TROUBLE CODE 
IDENTIFICATION . Repair as necessary.  

A/T BASIC SETTING 

Generic Scan Tool 

Connect scan tool to DLC. DLC is located at left side of steering column. See Fig. 1 . Turn ignition on, engine 
off. Follow scan tool manufacturer's instructions to initiate basic setting for A/T.  

Scan Tool VAG 1551/1552 Or VAS 5051/5052 

body, distorted throttle body or lose throttle body bolts), battery voltage is too 
low, engine is started or accelerator pedal is pressed during adaptation. 

NOTE:

A/T basic setting must be initiated when Engine, ECM (J220), A/T Control 
Module (J217), Throttle Valve Control Module (J338), or Accelerator Pedal 
Position (APP) sensor 1 (G79) and APP sensor 2 (G185) are replaced. (APP 
sensor 1 (G79) and APP sensor 2 (G185) are one unit, they are not adjustable 
and can not be replaced separately). It is also necessary to initiate A/T basic 
setting if idle speed has been adjusted.

1. Connect scan tool to DLC. DLC is located at left side of steering column. See Fig. 1 .  

2. Turn ignition on, with engine off.  

3. Using scan tool check for DTCs. See RETRIEVING DIAGNOSTIC TROUBLE CODES . If any 

DTCs are present, repair as necessary and clear codes. See CLEARING DIAGNOSTIC TROUBLE 
CODES .  

4. Initiate basic setting for A/T. Press keys "0" and "2" for address word "Transmission Electronics",

manufacturer's instructions for Immobilizer Adaptation.  

Scan Tool VAG 1551/1552 Or VAS 5051/5052 

1. Connect scan tool to DLC. DLC is located at left side of steering column. See Fig. 1 . Turn ignition on 

using a currently valid key, engine off. Press keys "0" and "1" for address word "Engine Electronics". 
Press "1" key 2 times for "Login Procedure" function 11 and enter by pressing "Q" key. Scratch off 

NOTE:

This article is for adapting new key and readapting currently valid keys only (it 
is necessary to readapt currently valid keys when adapting new key). 

NOTE:

Manufacturer recommends using Scan Tool VAG 1551/1552 or VAS 5051/5052. 
Starting with Model Year 2002 Golf and Jetta are equipped with Immobilizer 
Generation III (Starting 6/2001 for Beetle). Ignition keys for Immobilizer III may 
be marked "W3". For more reliable differentiation, always use the function 
"check control module version". Scan Tool VAS 5051 or 5052 must be used for 
Immobilizer Generation III diagnoses and coding. A correct Importer/Dealer 
number must reside in VAS 5051 or VAS 5052 in order to request a PIN number 
and to adapt Immobilizer Generation III. 

NOTE:

Three attempts to enter secret code number is initially possible. Next three 
attempts to enter secret code number is only possible after a minimum of 10 
minutes (with ignition remaining on during this time and OBD program is exited 
by function 06 "End Output"). Waiting period between each three attempts 
doubles each time up to a maximum of 255 minutes.
