wheel AUDI A4 2000 B5 / 1.G Brakes Erase DTC Memory End Output Workshop Manual

01-20

- End data transfer using the "End Output"
function. Disconnect VAG1551 Scan Tool (ST).

- Make sure all harness connectors are connected
and engaged. Perform a road test. The indicator
lamps must not light up during the drive. If the
indicator lamps light up during the road test,
repeat the troubleshooting procedure.

Note:
If the control module connector is disconnected
during the drive, an unfounded DTC may be
stored in the memory of another control module.
The brake system will only be partially functional.
Because brake pressure at the rear wheels is no
longer regulated vie Electronic Brake Distribution
(EBD), the rear wheels tend to brake
excessively. This causes the rear of the vehicle
to break loose. Driving the vehicle presents the
risk of accident.

- Always switch off ignition before carrying out
installation or repair work.
