ABS ITT Mark 20 IE On Board Diagnostic (OBD)

Function

Since the control modules are interconnected

with CAN-bus, always begin OBD by checking the Diagnostic Trouble Code (DTC) memories of all the control modules in the vehicle.

This occurs in the Automatic test sequence and

is activated with key function 00.

When doing this, check to see if there are

DTCs stored which may influence the ABS.

On Board Diagnostic (OBD) relates to the

electrical/electronic part of the ABS, i.e. only malfunctions via the electrical connection to the control module are recognized (e.g. speed sensor open circuit).

The 25-pin ABS Control Module (w/EDL) -J104-

forms with the hydraulic unit a compact unit. The unit is located on the left in the engine compartment. The control module is equipped with a DTC memory. The diagnostic connection is located in the center console below the heating/air conditioning controls.

The control module recognizes malfunctions

during vehicle operation and stores them in a permanent memory, the contents of which remain even during periods of no battery voltage.

Page 3

01-2

Sporadic (isolated) malfunctions will also be

recognized and stored. But if these malfunctions do not occur again within the next 50 vehicle starts and driving off sequences then, with the exception of "control module inoperative", the DTC memory will be erased.

After switching on the ignition and/or starting the

engine the ABS warning light -K47- and the warning light for brake system -K118- light up for approx. 2 seconds.

During this period a test sequence (self-check) is

run in the control module for the following functions:

To check if the supply voltage is at least 10.0 Volt

To check control module including the valve windings

To check the coding of the control module

A static check of the speed sensor (no speed signal)

If after driving off and exceeding a speed of approx. 20 km/h (approx. 13 mph) the speed signal is not OK. The ABS warning light -K47will light up again.

V.A.G 1551 Scan Tool or tester VAS 5051

The On Board Diagnostic (OBD) must be

initiated always at the commencement of troubleshooting. Electrical malfunctions which influence the braking characteristics will be stored. They can be checked with the V.A.G 1551 Scan Tool or with the tester VAS 5051.

The information displayed is used in

conjunction with a DTC table which has information on the possible DTC causes for repair measures.

Safety precautions

The ABS is a vehicle safety system; the appropriate knowledge is necessary to work on the system.

In order to check complaints and to be able to carry out pin-pointed troubleshooting, the Diagnostic Trouble Code (DTC) memory must be checked before beginning work on the ABS system.

Only separate connectors when the ignition is switched off.

Observe the appropriate instructions regarding the handling of brake fluid.

Repair Manual, Brake System, Repair Group

ABS malfunctions are indicated by the ABS warning light illuminating. Certain malfunctions will only be recognized at speeds above 20 km/h (approx. 13 mph) (carry out road test).

If the ABS Warning Light -K47- and the warning light for brake system -K118- do not light up, but the brake system is not functioning correctly then the malfunction must be sought in the conventional braking system.

Diagnostic Trouble Code (DTC) table

Note on DTC table:

When beginning OBD of the vehicle control modules, always start with function "Automatic test sequence" by pressing keys 0 and 0 because the control modules are interconnected with a data bus wire. This checks the DTC memories of the control modules in the vehicle.

All the possible DTCs which can be recognized by the ABS control module -J104- and printed-out on V.A.G 1551 or VAS 5051, are listed on the following pages according to the 5-digit DTC.

DTC appears (in the "Rapid data transfer" mode) only on the print-out.

Example:

DTC P code DTC type code 5-digit 5-digit 3-digit 18256 P1848 035

The 5-digit P code which may appear next to the DTC, is for use with the On Board Diagnostic (OBD) II and may be disregarded.

The 3-digit DTC type code is a data code and may be disregarded, but the DTC type text is of use.

Before replacing components indicated as being faulty, check all the appropriate connectors, wiring and Ground connections using the wiring diagram

Electrical Wiring Diagrams, Troubleshooting & Component Locations binder

On completion of repairs always check the DTC memory with V.A.G 1551 Scan Too. or the tester VAS 5051 and erase.

Carry out road test exceeding 20 km/h (13 mph).

After the road test check DTC memory again.

1. Carry out road test exceeding 20 km/h (13 mph),

2. Again check DTC memory, if there is still no DTC stored,

3. Continue troubleshooting without OBD and work through the complete Electrical check Page 01-102 .

Note:

All functions which could previously be

performed with V.A.G 1551 can also be performed with the tester VAS 5051.

The control module can transfer a considerable

amount of test data. This test data delivers information on the operational condition of the system and/or sensors connected to it. In many cases the transferred test data supports troubleshooting and repair. The test data has been summarized into single display groups because all the information cannot be evaluated at the same time. The information can be selected via display group numbers.

Safety precautions

Observe following if test and measuring

instruments are required during a test drive:

Test and measuring instruments must be secured to rear seat and operated by a 2nd person from this location.

When test and measuring instruments are operated from the front passenger seat there is a danger that the person sitting there could be injured in an accident when the airbag is triggered.

Note:

For display group number 002 remember:

The reading of measured value blocks in display group number 002 must be undertaken when driving off slowly. Then the ABS Control Module (w/EDL) -J104- will store the first usable voltage signals provided by the speed sensors and display these as a fixed value in the measured value block.

Output Diagnostic Test Mode (DTM)

Note:

All functions which could previously be performed with V.A.G 1551 can also be performed with the tester VAS 5051.

The pump motor and the correct functioning of the hydraulic circuits (allocation of brake lines to wheel cylinders and function of valves) can be checked via the output DTM for interchange or leaks.

The vehicle must be raised until all wheels are free to turn. (2nd mechanic required to rotate wheels)

The -C- key can be used to exit the test sequence at any time.

After depressing the brake pedal several times the vacuum in the brake booster will be exhausted. Therefore more pressure must be applied to the brake pedal in order to attain the same fluid pressure in brake system, as that attained with vacuum.

When vacuum in brake booster is exhausted wheels may not lock; start engine and build-up vacuum in brake booster.
