LCD DISPLAY

ENTER BUUTON

OBD II CONNECTOR

SCROOL BUTTON

1. LCD DISPLAY: shows the test results.

2. ENTER BUTTON: confirms a selection of a menu list, or returns to the main menu.

3. SCROLL BUTTON: Scrolls through menu items or cancel an operation.

4. OBD II CONNECTOR: Connects the B200 to the vehicle’s Data Link Connector (DLC)

DIRECTIONS

Making sense of the codes

1.) On the following pages, locate the correct chart for your car according to the first tow

digit number displayed by the tool:

1.)

Turn on key (DO NOT START CNGINE)

2.)

Plug tool into diagnostic connector Tool is ready to use when it displays “FA”.(Reverse

steps 1 and 2 if you encounter problems)

Code Reading Example:

3.)

Use the “Scroll” button to select one of the following functions:

After plugging in the tool, “FA” is displayed (See page 5)

Functions:

Read Airbag Faults.

How to Read Airbag Faults. The tool automatically starts in the “FA” mode, (though it won’t

read the fault codes until you press the “ENTER” button). When ENTER is pressed the first

number shown will be the correct code chart to use.

Note: if it shows “--”. There are on codes to display. Pressing ENTER a 2 nd time will display

the first fault code (see page 6 for explanation.) To view the next fault press ENTER again,

and so on. At the end of the fault list the display will show “--”.Press ENTER to return to

“FA”. lf you encounter problems see troubleshooting page 15”

Pressing ENTER will start the process. Before showing a code the tool will first tell you

which code chart to use:

First indication is the Chart #:

First indication is never a fault code! In this example, the tool is telling

you to use the chart labeled FF (see page 7)

Press ENTER again-the first code will be displayed, example:

Clear Airbag light/Faults:

How to Clear the Airbag (SRS) Light. It is important what you know exactly why the

airbag light came on before resetting it always read the code and look it up first.

This is an example of a code:“1b”(not 16)

2.) Look up the two digit code in the chart to obtain meaning

WARNING: DO NOT PROCEED WITH RESET UNTIL TAKING APPROPRIATE ACTION

TO DIAGNOSE, UNDERSTAND AND SOLUE THE PROBLEN WITH THE AIRBAG

SYSYEM.

1.) Using the “Scroll” button, select “CA”: Press “ENTER”

After resetting a code, drive vehicle over 15mph and re-check. lf code persists or the SRS

light returns contact a BMW dealer.

USE THESE CODE DEFINITIONS WISELY:

The code definitions contained in this manual should be regarded as a starting point for

diagnosing a problem. The codes that your BMW generates can be misleading. There may

also be errors in this manual. Before spending your money on a repair or replacement parts,

make sure you have a clear understanding of the problem.

The tool will reset the SRS light and display

If Airbag light does not appear to reset, or it cones right back on the moment you reset it,

then there is still a problem with the SRS system that needs to be fixed.
