SUBJECT:
New BMW Special Tool

Situation:





A new BMW Special Tool has been developed that allows the technician to diagnose ABS/ASC faults in cars with non-diagnosable control modules through the data link. For a complete list of affected cars see Service Information 34 05 92 (3692).

The ABS/ASC Tester is, and will remain the only approved method to test for faults in non-diagnosable ABS and ASC Control Modules. Therefore, in the interest of improved customer satisfaction and warranty reduction of control modules that have been replaced incorrectly, the ABS/ASC Tester is a mandatory tool.

This tool will be sent out via the Automatic Tool Shipment Program. Additional tools may be purchased through your PDC.

Features and Advantages of the ABS/ASC Tester

^ Stores faults in memory.

^ Component status.

^ Component activation

^ A special test diskette is included that is matched to the tester making the diagnosis of sporadic faults possible.

^ Considerably shorter function test.

^ 35 pin ABS and 55 pin ABS/ASC system can be tested.

^ Tester can be mounted and the car road tested. The tester allows for fault storage and evaluation.

^ The ABS/ASC Tester has been produced with future evaluation systems in mind. It is not limited to the current service tester.

^ When Version 3.0 MoDiC Diagnostic Software is replaced, the ABS/ASC Tester can be used in conjunction with the MoDiC.

ABS/ASC Tester Tips

^ In cars where the ABS/ASC Control Module is located in the E-Box, remove the car's standard control module and replace it with the test module and adapter. This will allow you to close the engine's hood for test drive purposes.

^ Before you turn the ignition off, page back (up arrow) as far as you can. If this is not performed, "Data Transmission Disturbed" will be displayed and you will have to reboot the service tester in order to continue.

^ Please be advised of the following error in the provided software. The error in no way adversely affects the diagnostic capabilities of the ABS/ ASC Tester.

Number two (2) on the main menu, "Status Request," will bring you into two input signal screens. The first screen is for pulse gears with 48 teeth. At the bottom of this screen it says "Pulse Gears, 48 Teeth." This phrase should be on the next page.

^ Read the instruction book completely before using the tester.

^ Be sure to erase the fault memory of the Test Module before starting to perform diagnostics. The person that used the tool before you may have left faults in its memory.
