Operation Number Structure for Diagnosis Jobs

Diagnosis activities are to be coded within the structure of the operation number group.

These operation codes are grouped together in the respective design groups with the number range XX-0640 to XX-0999 (see the table below) and are always assigned to the system to be

diagnosed. Generally, "54-1011 Perform quick test" will be used when starting diagnosis. After the quick test, the system test for each of the design groups will be listed.

If it is necessary to perform another quick test in the course of the repair order, then this must be invoiced via the operation codes for diagnosis and testing work.

The diagnosis structure following on the quick test depends on whether a fault code has been

stored for the customer complaint. This should be taken into account when preparing the order.

The following application rule always applies to the necessary test operations:

1. Use of the operation code with the ending "O"e.g. XX-0640, XX-0660, XX-0700, ... ), if: no fault code is stored but a reproducible customer complaint is present and further test operations are necessary

2. Use of operation codes with the ending "1" (e.g. XX-0641 , XX-0661 , XX-0701 , ... ),if : a fault code has been stored.

3. The joint use of diagnostic operations, e.g. XX-0640 and XX-0641 , is permissible only in justified cases. The justification for common use must be entered in the message field or the operation item may be rejected. This would be a unique circumstance.

Some specific tests are applied as individual operation codes with working hours or ZM time such as (but not limited to) :

• Check fuel low pressure circuit • Check throttle valve actuator

• Check charging system for leaks

In the case of engine subjects, operation codes are established for the fo llowing individual

component tests under operation code 07-0641 "Check separate parts of engine ... .... ...... as per fault code" :

• Check coolant temperature sensor

• Check intake air temperature sensor

• Check hot film MAF sensor

• Check charge air temperature sensor

• Check intake port shutoff

• Check leakage quantity of injectors

• Check knock control

• Check ignition coils (secondary side)

• Check oil sensor

• Check intake manifold pressure sensor

The following operation numbers and operation texts have been applied for selected models for processing of complaints in the telematics area:

• 82-0702 Check radiorrv • 82-0703 Check screen • 82-0704 Check CD-drive/changer and CC drive • 82-0705 Check navigation system • 82-0706 Check telephone/cell phone • 82-0707 Check fiber optic cable and wake-up signal • 82-0708 Check antennae

On some selected models the operation items listed replace operation item 82-0700 "Check communication system (after quick test)".

Telematics diagnosis operations on the model series without published operation codes listed above should be carried out under operation codes 82-0700 and 82-0701 .

In all other design groups, the structure and procedures for the diagnosis work on control units with fault codes is shown in the same way.

The operation code 82-9905 for COMAND remains valid . Items 80-XXXX for key programming or

teach-in remain unchanged.

The operation code 54-101 O "Check electrical system, establish findings" or 82-1015 " Establish diagnosis on the electrica l system" are available for diagnosis work, if no special diagnosis operation item is available within the affected design group. Combination of this/these operation codes with test items of the diagnosis structure described is not permissible.
