Connect scan tool. See RETRIEVING DIAGNOSTIC TROUBLE CODES . Turn ignition on. If using other 
than Scan Tool (VAG 1551/1552 or VAS 5051/5052), follow scan tool manufacturer's instructions. Using Scan 
Tool (VAG 1551/1552 or VAS 5051/5052), select address word 19, select function 7, enter 00006 (ABS 
activated 00002 + Airbag activated 00004 = 00006).  

THROTTLE VALVE CONTROL MODULE (J338) 

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). See step 1 under Adapting Throttle Valve Control Module (Scan Tool VAG 
1551/1552 Or VAS 5051/5052). If using generic scan tool, follow scan tool manufacturer's instructions.  

Adapting Throttle Valve Control Module (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.  

Adapting Throttle Valve Control Module (Scan Tool VAG 1551/1552 Or VAS 5051/5052) 

NOTE:

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 use of Scan Tool VAG 1551/1552 or VAS 5051/5052. 

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 body, distorted 
throttle body or lose throttle body bolts), battery voltage is too low, engine is 
started or accelerator pedal is pressed during adaptation. If TVCM does not 
adapt to ECM, wiring to TVCM or TVCM may be at fault. Check for DTCs. See 
DIAGNOSTIC TROUBLE CODE IDENTIFICATION . Repair as necessary.

in this position for 3 seconds. Press right arrow key. 

NOTE:

There is no A/T basic setting for Passat, (it uses a TCM that does not require 
basic setting procedure). 

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.

manufacturer's instructions for Immobilizer Adaptation.  

Immobilizer Adaptation To ECM (J220) (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 
protective coating on new key and read secret code number of new key. Key in secret code number 
preceded by a "0"into scan tool, e.g. "0", "1", "9", "1" and "5" if secret code number is 1915 and enter by 
pressing "Q" key. If "Rapid Data Transfer Select Function XX HELP" displays on scan tool, secret code 
number has been accepted, leave key in on position and go to next step. If "Test Sends Address Word 17" 
displays on scan tool. Repeat adaptation procedure and re-enter secret code number.  

2. Press keys "1" and "0" for "Adaptation" function 10 and enter by pressing "Q" key. Press keys "2" and 

"1" for "Channel 21" and enter by pressing "Q" key. If "Channel 21 Adapting 2 <-1 3->" displays on scan 
tool, press right arrow key. Go to next step. If "Function Is Unknown Or Can Not Be Carried Out At The 
Moment" displays on scan tool. Repeat adaptation procedure and re-enter secret code number. 

NOTE:

This article is for adapting new key(s) and readapting currently valid keys only 
(it is necessary to readapt currently valid keys when adapting new key). For 
immobilizer system diagnostics. See appropriate DOOR LOCKS & ANTI-THEFT 
SYSTEMS, under ACCESSORIES & EQUIPMENT. 

NOTE:

Warning Light for Anti-Theft Immobilizer (K117) is located in speedometer 
gauge. Properly functioning immobilizer system is indicated by warning light 
for Anti-Theft Immobilizer (K117) lighting up and going out after approximately 3 
seconds when ignition is turned on. Malfunction in immobilizer system is 
indicated, when ignition is turned on and warning light flashes or lights up 
continuously. For immobilizer system diagnostics. See appropriate DOOR 
LOCKS & ANTI-THEFT SYSTEMS, under ACCESSORIES & EQUIPMENT. 

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.
