Notes:
^
The channels 1 to 4 indicate the wheel speed in km/h. This is calculated by the ABS Control Module - J104 per input from wheel speed sensor
pulses.
If the vehicle is accelerated or moved evenly on a dry surface, a deviation between the readouts 1 to 4 of up to +/- 1 km/h is permissible.
If the difference is greater, check wheel speed sensors and rotors (Check Repair Group 45).
^
To check whether the sensors are correctly connected, turn the wheels by hand (block the other wheel of the driven axle to prevent it also turning).
If the readings obtained indicate a malfunction, perform function test with ABS tester VAG 1710.
