 Test table: display group 1  
Notes:  
 
Display fields 1 through 4 show the current wheel circumference speeds in km/h. These are calculated by the ABS control 
module -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" DTC table   page 01
-98
 . 
 In order to check whether wheel speed sensors are properly allocated to each wheel, 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 appropriate wheel by hand. Remaining drive wheels must be secured against turning. 
 When a vehicle is accelerated uniformly on a dry surface, the displayed value will increase continuously by whole 
numbers; e.g. 6 km/h, 7 km/h, 8 km/h ... . The difference between displayed values 1 to 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.  Repair Manual, Suspension, Wheels, Steering, Repair Group 40
