The program allows the diagnosis of complaints via: • Fault driven test plans • Fault Symptom driven test plans • Manual override of test plans (Control Unit Function) The program also incorporates electronic wiring diagrams for the vehicle and an automatic interface with measuring systems during test plans. Diagnostic Head Connection To start diagnosing the vehicle, a connection to a diagnostic head is needed. This connection can be performed via connection setup from either the DIS administration screen or while in the diagnosis program. haldlii mi i>V'- I -^r-1 ‘I From the DIS main start up screen, Select “Administration”.

For automatic ID, the DISplus or GT1 reads the ZCS code to determine what systems are installed in the vehicle and directly seeks them out. This process is much faster than pre¬ vious method of polling all systems possible for a specific vehicle series. If the D bus is faulted or the tester can not communicate for whatever reason, Manual ID is required. If automatic determination was suc¬ cessful, this screen will be displayed. From here you can decide to auto¬ matically perform a short test once the vehicle is automatically deter¬ mined. If automatic determination is not suc¬ cessful, the following screen will be displayed.

The Fault symptom selection screen displays all fault memories set for troubleshooting purposes. Service technicians can enter fault symptoms observed by themselves or by the vehicle owner. This is done by selecting the appropriate items in a predefined list of symptoms. Several fault symptoms can be selected simultaneously. Use the transfer key to transfer selected fault symptoms into the display. The test schedule is generated on the basis of both the symptoms observed by customers or service tech’s and the contents of the fault memories.

Test results are continually analyzed, and the inspection plan is revised accordingly. The results of tests already completed influence the order of preference set up for remaining test modules. Use the continue arrow to proceed to the next test. DISplus/GT 1 highlights the test which should be carried out next (dark background). The results of tests already completed are indicated to the left of the test designations. Note: 1. The test schedule is revised each time the “test schedule” screen is re-entered following the completion of a module. If a fault has been rectified or its symptoms have changed, this is indicated in the “Inspection plan” display (sequence of test modules). 2. Fault memory contents are assessed according to various criteria (e.g. frequency, temperature). 11 BMW Diagnosis Test Information Press the continue arrow to advance to the next test schedule. The Test Information screen appears automatically. The test information screen automatically displays documents containing any pertinent information needed to diagnose the fault. This information may include: • Wiring Schematics, • Functional descriptions, • Connector locations, etc. The Test Dialog box displays test points and nominal values automatically. This screen format is used throughout the diagnostic software for all systems. 12 BMW Diagnosis Measurement System Integration All measurements now relate to circuit name acronyms that are “hot spot” activated (if needed). Nominal values are displayed with the actual measured display. Simply answer the question the system provides in response to the measured value.

It displays auto¬ matically when needed by the test plan. The test plan utilizes the MFK 1 leads as an input for the measurement. By press¬ ing start, the measurement is automati¬ cally taken from these leads. Note: If the test plan needs KLR or KL15 status it can obtain these results from the diag¬ nostic head if hard wired. If you are using a DVOM for measuring the values in place of the MFK leads, you can enter the measured values into the system and follow the test plan as follows: • Press the measurement system value display bar to bring up a “key pad”. • Enter the measured value into the key pad and press the enter button. The “keyed in” values will be used. tiiin 13 BMW Diagnosis End of Diagnosis There are three options available on the end “drop down” menu of the software. __ _ ■ ■ ■ - _ - ■ " - ■ ■ »_ L ■ ai _ i i J 1 LJB- ^UBm | ||dU B S 1-1 ^1 ■ L IF 1 H J Sa" 1 ... . ... . a a * a cxLu>_7*nr& I-^hty mu I j| ■r:-rk. un Bin jrliKp it^alun -=-n 1 1 > vkiLh | pin filling nurr^npri^il' Ciin'-p^ 1 I L'jir -i'J. {urfiul m-z-zkilfc und irtldlur nrty with botlMy rlurnnnp-dF-d vcrwi mum llhnjrtiiq rrnlrr* nnriuk rr-cl?ini vthkl» ifhKd'; d 9 il» >id iiutl t>£- onicad^id IprhJi lu iiifcjl ujjumlhL-n Tlhk L:-nlr-:-! nuiluh mu* rrattk rtnm*4 swd ■’JialL*d nottiir IV k 111 LIL ■' Three options when ending a session: • Break • Cancel • Quit Canceling a Session • rilH h rni ■illrflmi AF u|iirwtMiQ midi T-a Einurrl a z-n -n - ij n r-rl p zmt -r. fir-- c-z ("nmirr;- tTWHttm etcnif- vd ^nt"i rd |:m'j rtkirfr11 udzri.iD -ipdil lUZZ 1 ZK : r Z3 MTiZIZIl TK \ KCEI I 1 u fyilkn lti I f ■ r-11 ■dt rrirl irrftrte-r nannrlrd Uufkcltlrt* 3ligmJ*-rap£>l lf<. . rp-ZJj U 4 riL jC rnC Lr nruMtl and mlallid n zfliH Vkllkdfll nhy M ctmiii nintir Dl 9 llf^£t£ 0 tll ■ i 1 1 ■ ■ I ■.- A dialog box reminds you to print the diagno¬ sis report.

Hint: The Diagnostic Report will be stored. To print select “Stored Diagnosis Report” from the Print menu. If manual determination was used a dialog box asking for the chassis number appears before the reminder box. The program uses the chassis number entered for the diagnostic report. 14 BMW Diagnosis Break - Pausing/Interrupting a Session This feature allows the session to be “stopped” temporarily and resumed at a later time. Example: A co-worker needs to clear faults on a waiter vehicle. Your diagnosis might take another 20 minutes. If you select “Pause”, the faults on the other vehi¬ cle can be cleared and afterwards you can resume in the exact same position you left off.

Schematics are in the left box only and can be dis¬ played as full page or left half of the screen. Only one schematic may be viewed at a time. Highlight the schematic (4) and press the “Display”button (5). Linked pages to a diagram are accessed by highlighting a Hotspot. If the Hotspot changes color from green to amber then there is linked information available. The infor¬ mation is accessed by touching the Document button and selecting the “new” docu¬ ment.

Screen 2. Documents (only if the top hotbox #3 is selected first) Note: If the hotbox above a component location picture orpin assignment page is selected the entire contents of that box will be printed. 1 L'.iT i w t 7E:-Tnra ■y.'.'

If the schematic is larger than what is displayed, the entire diagram will not be printed. Note: If a picture is displayed when print screen is selected, the picture output is very low resolution and can be illegible. The better way to print it out would be using the print document function. 28 BMW Diagnosis ■ Print Document Highlight the green frame which is around the title of the schematic, component location, pin assignment page, etc. Then press the Print button and select Document (2). The printed schematic will include: the date, time, page number, description of the circuit and vehicle information. Samples of printouts using the “print document” feature. The following document abbreviations can be found in the header of the document window (2) or display boxes (1).
