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) -J104forms 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.

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 47 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.

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.

ABS Mark 60 On Board Diagnostic (OBD), vehicles from my 10.00 There are four versions of the ABS Mark 60. ABS ABS/EDL/ASR ABS/EDL/ASR/ESP with front wheel drive ABS/EDL/ASR/ESP with 4MOTION Each version has its own control module. The control modules can be coded accordingly through coding bridges via tester VAS 5051 or V.A.G 1551. The ESP (Electronic Stabilization Program) is an electronic dynamics Program (EDP). It stabilizes the vehicle when oversteering or understeering. The ESP works over the whole speed range. If the ESP is regulating the system the ESP warning lamp will flash 3 times per second. The ESP is a further extension of the familiar vehicle safety systems. ESP increases control over the vehicle in critical situations. It reduces the danger of skidding and increases the steering control when compared with familiar vehicle safety systems.

Function As the control modules are interconnected with a data bus wire, always start troubleshooting by the Diagnostic Trouble Code (DTC) memories of all the control modules in the vehicle. This occurs in "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. The On Board Diagnostic (OBD) relates to the electrical/electronic part of the ABS, in other words only malfunctions via the electrical connection to the control module are recognized (e.g. speed sensor open circuit). The 47 pin ABS Control Module (w/EDL) -J104forms with the hydraulic unit a compact unit. The unit is located on the left of the engine compartment. The control module is equipped with a DTC memory. The Data Link Connector (DLC) 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.

Sporadic (irregular) malfunctions will also be recognized and stored. But if malfunctions affecting the data bus system do not occur again within the next 15 vehicle start and driving off sequences, or other malfunctions within the next 50 vehicle start and driving off sequences, they will be erased from DTC memory except for the malfunction "Control module faulty" (forgetmalfunction counter). After switching on the ignition and/or starting the engine, the ABS warning light -K47- and the ESP control lamp -K155- will 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 the wheel speed signal is not OK after the car has been driven and a speed of approx. 20 km/h (approx. 13 mph) has been exceeded, the ABS warning light -K47- will light up again.

Safety precautions and fundamental points regarding troubleshooting Note: 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 commencing 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 47 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 -K47- and the brake system -K118warning lights do not illuminate, but the brake system is not functioning correctly then the malfunction must be sought in the conventional braking system.

Measured value block, reading Note: All functions that have been carried out so far with V.A.G 1551 can now also be carried out 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 WARNING! If the use of test and information devices during a test drive is necessary, observe the following: You must always secure testing and measuring equipment on the rear seat. When vehicle is being driven, a second technician must operate this equipment.

Brake pressure release solenoid -F84The trip switch is installed in the brake booster and is required by the control module to recognize the braking desired by the driver. Magnetic coil for brake pressure, in brake booster, -N247The brake pressure solenoid is installed in the brake booster and ensures that a pre-pressure of 10 bar is available for the ABS/ESP pump. Read measured value block 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 malfunction 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.
