Test table: display group 1 (001)
NOTE:
- Display fields 1 to 4 show the actual wheel speeds in km/h. These are calculated by the ABS Control Module (w/EDL) - J104- on the basis of the signals received from the wheel speed sensors. If one of the display fields shows no reading, proceed as for DTCs 00283, 00285, 00287, 00290 "ABS Wheel Speed Sensor". See DTC TABLE; DTCS 00000 TO 00526 .
- In order to check that the wheel speed sensor signals are correctly assigned to the four wheels, the vehicle must be raised. On vehicles with manual transmission put the gear shift lever in neutral. On vehicles with automatic transmission move the selector lever to position "N." Turn the relevant wheel by hand, and at the same time prevent the other wheels from rotating.
- When the vehicle is accelerated uniformly on a dry surface, the displayed value will increase continuously in rising whole numbers (e.g. 6 km/h, km/h, 8 km/h...). The difference between displayed values 1-4 should not be more than +/-1 km/h (error from out-of-round wheels). If the values jump, for instance from ... 6km/h, 7 km/h to 12 km/h... or if the difference between the displayed values is greater than +/-1 km/h, then check the installation of the wheel speed sensors and rotors.
See SUSPENSION - FRONT or SUSPENSION - REAR .
1) OBD is terminated by ABS Control Module (w/EDL) -J104- if road speed exceeds 19 km/jh (12 MPH). 1 Km/h is the minimum speed that can be displayed (at 0 Km/h, for example, the tester, displays 1 Km/h).
NOTE:
The display group numbers can be selected in sequence by pressing buttons <-1 and 3-> on the VAG1551 scan tool, arrow buttons "UP" and "DOWN" on the VAG1552 scan tool, or the arrow buttons "UP" and "DOWN" on the screen of the VAS5051 tester.
