Safety precautions and troubleshooting
basics


ABS/EDL/ASR and ESP are vehicle safety
systems; working on these systems requires
specific system knowledge.
There are two different versions of instrument
cluster: with or without Driver Information
System (DIS).

Instrument cluster without DIS
If On Board Diagnostic (OBD) has detected a malfunction in the
system, it indicates the malfunction by lighting up warning lamps when
ignition is switched on. The warning lamps are located in the
instrument cluster. This appears in both versions, with or without DIS.
The instrument cluster without DIS displays the ABS warning light -
K47- (right arrow), the warning light for brake system -K118- (center
arrow, red symbol for "brake system malfunction") and the traction
control indicator light -K86- (left arrow). For additional information, see
the section titled "Overview of indicator lamp functions".

Instrument cluster with DIS
Repair manual, Brake System, Repair Group 45; ESP component overview

For DIS, the warning light for brake system -K118- "brake system
malfunction" appears in the display. If the ABS warning light -K47 and the red symbol for "Brake system
malfunction" are not lit, but the brake system is not functioning
properly, check for malfunctions in the mechanical/hydraulic brake
system components.

Corrective actions


If a malfunction or problem has been
detected or reported, perform guided
troubleshooting:

- First switch on the ignition, and note whether the
indicator lamps light up. The table in the section
"Overview of indicator lamp functions" for the
relevant system facilitates an initial diagnosis.

- Fulfill test requirements.

- Connect the VAG1551 Scan Tool (ST) and
select the address word 03 "Brake Electronics".

- Check the control module version Parts
Catalog and press the button.

- Check DTC memory. If a DTC is stored: Note
the DTC and erase DTC memory page 01
-
15
.

- End data transfer using the "End Output"
function page 01
-16
.

- Repair the malfunction with the help of the DTC
table. Select again the address word 03 "Brake
Electronics". Check and erase DTC memory.

- 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.
