Diagnostic Cable

The Diagnostic Cable is used to connect the diagnostic head to a vehicle with the 20 pin underhood connector. The cable consists of the 20 pin connector, the cable and the 21 pin plug for connection to the head (bottom left).

OBD Diagnostic Cable

The OBD Diagnostic Cable is used to connect the diagnostic head to the OBD II diagnostic connector (upper right).

Diagnostic Head

The Diagnostic Head enables operation of the diagnostic interface via either radio or cable communication.

DIAGNOSTIC HEAD LED COLOR AND FUNCTION

Scheme 597

Scheme 597
SymptomPossible CausesRemedy
No connection possible (LED 1 on diagnostic head is dark).No Power supply of the diagnostic head via vehicle electrical systems.First check the plug-in contact on the BMW or OBD diagnostic cable and its connection to the vehicle. Switch on the ignition. If the LED still does not light up, send a Fault Report Fax.
Connection to the diagnostic head not possible or faulty (LED 2 flashes yellow); no diagnostic head is recognized (see "Administration, Diagnostic Head Allocation" window). The diagnostic head cannot be connected.Interference due to excessive distance from the vehicle; in the case of radio link, may also be due to external radio sources or absorption. Diagnostic head software defective. Incorrect IP address when the diagnostic head was changed. Radio card in the diagnostic head defective. Radio card in the control panel is defective.Check the correct connection of the cables at the diagnostic head. Change the location of the diagnostic head and, if necessary, of the control panel. If this does not remedy the fault, change the connection type. If there is still no connection, send a Fault Report Fax. Perform a reinstallation in accordance with Section 7.7 Check the IP address in the "Administration, Network configuration" window. If possible, use the second diagnostic head to check the radio link. If the connection can be established, the card in the first diagnostic head is defective. Send a Fault Report Fax. If possible, use the second diagnostic head to check the radio link. If no connection can be established with this head either, the card in the control panel might be defective. Using a suitable tool (such as a screwdriver), pry the cover off the radio card slot in the left handle of the control panel ( see scheme 71); you will then se one green and one yellow LED on the radio board. If the green LED is lit, the radio board is OK. If the yellow LED is flashing rapidly, data transmission is being formed correctly. If the LEDs are in any other state, send a Fault Report Fax.
LED 3 Flashing RedInterior temperature of the diagnostic head is too high.Terminate the diagnosis. Terminate the connection and allow the diagnostic head to cool adequately before using it again.
LED1 flashing rapidlyGeneral fault in the diagnostic head.Send a Fault Report Fax.
"Recorder" button on the back lights up in green.Only while booting.Not a Fault. This button has not function at this time.

Scheme 598: Optical Testing and Programming System - OPPS

OPPS (Optical testing and Programming System) is a device that may be used instead of the Diagnostic Head as a vehicle interface for either the DISplus or GT1. When used, it replaces the Diagnostic Head. OPPS was developed to reduce the amount of time required to program E65/E66 MOST control modules by 30-60% and to diagnose the Fiber Optic communication systems MOST and Byteflight. OPPS can be connected into the MOST bus and the OBD connector simultaneously.

Refer to E65 CIP PROGRAMMING SETUP below, for details on how to connect and make use of OPPS for CIP programming. Each OPPS unit will have the Network settings for your service workshop configured when you receive it. API International has been contracted to perform this service

  1. No loading or configuring necessary upon receipt of the OPPS.

Note. OPPS is delivered with newer operating software than is available through the DISplus/GT1. Do not under any circumstances perform an OPPS software update available in "Connection Setup" or if automatically prompted by the DISplus/GT1 software until CD32. If an update is performed before CD32 the OPPS will be non-operational and must be returned for repair.

All OPPS units remain the property of BMW of North America LLC. Centers may not sell, transfer or assign any third party to use the OPPS and its software.

Cabling Setups

There are 2 different cabling setups that are addressed in this section. Each is used for E65/E66 programming and MOST/Byteflight diagnosis. Each OPPS will require 1 Network IP address and 1 wall mounted LAN receptacle. API has acquired the additional IP address (es) for each center.

If upon receiving your OPPS the workshop has a sufficient number of LAN receptacles, use cable setup #2. If the workshop does not have a sufficient number of wall mounted LAN receptacles, use cable setup #1. The following is an overview of the 2 different cabling setups.

  1. Cable setup #1 This setup should be used if the OPPS is operated independent of the workshop network.
  2. Cable setup #2 This setup should be used if the OPPS is operated on the workshop network.

E65/E66 Optical Bus And Harness Testing Setup

Attach the OPPS and GT1 in accordance to Cabling setup 1 or 2. Follow the directions in the Diagnostic program test module. The following is an example of how to test the SVS module and the SVS fiber optic harness.

Note. Always consult the "Operating Instruction" books supplied with the OPPS and the "Functional Description" section in the DISplus/GT1 Test Modules for complete testing instructions.

  1. For SVS Optical CM testing you will need Control module cable (663 122) OR
  2. For SVS Optical CM harness testing you will need Control module harness cable (663 123)
  3. Attach the Long OBD cable (3) to the OPPS
  4. Attach the DK LAN cable (4) to the OPPS
  5. During the Test module you will be instructed to attach the MOST test loop P/N 663 124 (2) to the OPPS as illustrated.

Note. This is a crucial step and must not be ignored. Failure to complete this step will result in incorrect readings and results.

  1. Next you are instructed to attach the MOST control unit cable P/N 663 122 (2) and the MOST test loop P/N 663 124 (4). This is a crucial step and must not be ignored. Failure to complete this step will result in incorrect readings and results.
  2. Remove the test loop
  3. Remove the SVS harness from the module
  4. Remove the fiber optical insert (4) from the SVS harness plug.
  5. Insert the free end of the MOST CM cable P/N 663 122 (5) into the SVS harness plug and plug the assembly into the SVS module.
  6. Follow the DISplus/GT1 test module instructions.
