DIAGNOSTIC TROUBLE CODE (DTC) TABLE 

NOTE:

z

When beginning troubleshooting of the vehicle control modules, always 
start with "Automatic Test Sequence" address word 00 by pressing 
buttons -0- and -0-, because the control modules are interconnected with a 
CAN-bus wire. This checks DTC memory of the control modules in the 
vehicle.  

z

All the possible malfunctions which can be recognized by ABS control 
module (w/EDL) -J104- and printed-out on VAG1551 are listed on the 
following pages according to the 5 digit DTC.  

z

DTC appears (in the "Rapid data transfer" mode) only on the print-out.

Example: 

DTC Malfunction code 

5 digit 3 digit 

00283 035 

z

The 3 digit malfunction code next to the DTC can be disregarded, but the 
text describing the malfunction type is relevant.  

z

Reference is made to individual "Electrical testing" test steps in the 
"Corrective action" column.  

z

Before replacing components indicated as being faulty, check all the 
appropriate harness connectors, wiring and Ground (GND) connections 
using the wiring diagram.  

z

After carrying out repairs, always check and erase DTC memory with the 
VAG1551 scan tool. Road test at a speed exceeding 20 km/h (13 mph).  

z

After the road test, check DTC memory again.
