Basic Setting (Function 04)
Note:
^ All functions previously performed the VAG1551 can also be performed using the VAS5051 tester.
Function 04 "Initiate basic setting" fulfills three objectives for ESP:
The Steering Angle Sensor -G85- is zeroed via display group 001.
Before zeroing, use the VAG1551 to code the ABS control module (w/EDL) -J104- and then complete function 11 "Login procedure".
This is necessary if:
^ the ABS control module (w/EDL) -J104-, the Steering Angle Sensor -G85-, or the steering column was replaced.
^ Adjustments are made to the running gear during a vehicle alignment.
^ If the DTC table instructs you to zero the sensor based on a DTC in DTC memory of the ABS Control Module (w/EDL) -J104-.
The Hydraulic pump for traction control -V156- is activated using display group 2.
Activation of the hydraulic pump does not require any preparations. It is used to bleed the hydraulic system
The ESP driving test is activated using display group 003.
The ESP driving test is used to test the plausibility of the signals from the sensor for transverse acceleration -G200-, sender for rotation rate -G202- and Sender 1 for brake booster-G201-.
Display group 1: Zeroing the Steering Angle Sensor -G85-
^ Switch engine on.
^ Turn the steering wheel one turn to the right and one turn to the left.
^ Carry out a brief road test on a level surface. Drive straight-ahead and not faster than 20 km/h, note the information two points.
^ If the steering wheel is not in the center position when driving straight-ahead, steering wheel position must be corrected within a vehicle alignment.
^ Perform zeroing.
^ If the steering wheel is level during the road test, stop the car.
Be sure not to dislodge steering wheel from center position. Do not switch ignition off.
^ First perform "Login procedure" function 11 successfully using the VAG1551 Scan Tool (ST).
Indicated on display:
^ Press buttons -0- and -8-. (04 selects "Initiate basic setting", function 4.)
Indicated on display:
^ Press -Q- button to confirm input.
Indicated on display:
^ Press buttons -0-, -0- and -1-.
^ Press -Q- button to confirm input.
If this appears in display, the "Login Procedure" has not been successfully completed.
^ Repeat login procedure.
Indicated on display:
^ Check the zero position using "Read Measuring Value Block"
or
Indicated on display:
1. Check DTC memory (function 02)
2. Erase DTC memory (function 05)
3. End Output (function 06)
4. Switch ignition off.
5. Switch ignition on.
6. Then repeat zeroing.
^ Press -> button.

Display group 2: Activating Hydraulic pump for traction control -V156-
Activation of the hydraulic pump does not require any preparations. It is used to bleed the hydraulic system.
^ Connect VAG1551 scan tool and select the control module for brake electronics with ignition switched on (address word 03).
Indicated on display:
^ Press buttons -0- and -8-. (04 selects "Initiate basic setting", function 4.)
Indicated on display:
^ Press -Q- button to confirm input.
Indicated on display:
^ Press buttons -0-, -0- and -2-.
^ Press -Q- button to confirm input.
Indicated on display:
Hydraulic pump will be activated for 10 seconds
^ Press -> button.
Indicated on display:
Display group 3: Activating ESP driving test
The ESP driving test is used to test the plausibility of the signals from the sensor for transverse acceleration -G202-, sender for rotation rate -G202- and Sender 1 for brake booster -G201-.
The ESP driving test should be carried out after any components of the ESP system are removed or replaced.
^ Once the ESP driving test has been initiated, it cannot be aborted and must be performed completely.
^ Connect VAG1551 scan tool and select the control module for brake electronics with ignition switched on (address word 03).
Indicated on display:
^ Press buttons -0- and -8-. (04 selects "Initiate basic setting", function 4.)
Indicated on display:
^ Press -Q- button to confirm input.
Indicated on display.
^ Press buttons -0-, -0- and -3-.
^ Press -Q- button to confirm input.
Indicated on display:
The ESP driving test is activated.
The ABS Warning Light -K47- and the ESP Control Lamp -K155- light up.
^ Press -> button.
Indicated on display:
^ Disconnect diagnostic connection.
^ Start engine.
^ Depress brake pedal forcefully (brake pressure higher than 35 bar) until the ESP Control Lamp -K155- goes out.
Note:
^ This completes the adjustment with the engine not running
^ Perform the road test:
^ Drive around a right (left) curve and then around a left (right) curve.
^ After these curves, drive straight-ahead for awhile.
Note:
^ The ABS Warning Light -K47- must go out. This represents successful completion of the ESP driving test.
WARNING! Always follow the rules of file road and pay attention to traffic conditions as first priorities.
Notes:
^ While driving around the curves, a rotation rate of around 10 User must be obtained. A curve with a radius of 10 - 12 m and a speed of 15 - 20 km/h for around 4 sec. fulfills this requirement.
^ Road test must not require the use of ABS, EDL, ASR or ESP.
^ Other maneuvers required while driving around the curves (i.e. due to traffic conditions) will not influence the test.
^ If the ABS Warning Light -K47- does not go out, the ESP driving test was not performed properly.
^ If the ABS Warning Light -K47- does not go out, and the ESP Control Lamp -K155- lights up again, check DTC memory.
