turn signal AUDI A4 2000 B5 / 1.G Brakes Read Mesure Value Block Workshop Manual

01-63
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

DTC
00532
Voltage supply
Signal too small

Notes:

This malfunction affects the voltage supply
of the control module.
This DTC is only stored, if the malfunction
occurs at a vehicle speed above 6 km/h.
As soon as vehicle voltage is within the
valid voltage range again, the ABS,
ABS/EDL or ASR system is switched back
on and the warning lights turn off.
Open circuit or resistance too high
between voltage supply of terminal 15
and ABS control module -J104-
(terminal 1). Voltage jumps in vehicle system.Battery malfunctioning.
