00 00 ... CBS reset

The CBS service jobs can be reset in the car with the on-board computer button on the direction indicator/main-beam switch. It is only possible to code the statutory intervals specific to individual countries with the diagnosis system. It is always recommended to reset the CBS jobs via the diagnosis system.

Resetting service-relevant jobs

CBS reset in the car

Note. First carry out the service measure. Resetting of a service job must always be carried out after the service measure has been completed.

Note. Perform reset according to instructions. The resetting procedure is aborted by a timeout or a terminal change.

The service jobs can be reset in the car at the instrument cluster. Here, the availability of a service job is set to 100 % again (corresponding to a new part).

The availability is an internal computing value (not visible to the user).

Observe the following procedure when resetting with the trip odometer reset button

1. Switch on terminal 15.
2. Press the trip odometer reset button for approx. 10 seconds until the 1st service job appears in the LC display.
3. The upper display in the speedometer is illuminated by a service symbol (e.g.: an oil can denotes an oil change). The lower display in the speedometer indicates the time or distance remaining until the next service (e.g.: 14000). Set desired maintenance scope with the rocker switch on the direction indicator/main-beam switch.
4. To reset, press the on-board computer button on the direction indicator/main-beam switch until the message "RESET" appears.
5. Resetting is confirmed by pressing the on-board computer button for a slightly longer period.
6. A clock is displayed during resetting.
7. A check/tick is displayed after "RESET" on successful resetting.
8. Repeat the procedure for each additional service which is to be reset.

Note. Resetting increases the service counter. Each reset increases the service counter of the respective job by 1. The service counter is used in the SAM on a job-specific basis to control additional tasks.

Note. Sorting is chronological. The service jobs are sorted in chronological order. The most critical job is displayed first.

Note. Vehicle inspection and exhaust emission test are country-specific. The statutory intervals specific to individual countries are coded with the diagnosis system.

CBS reset with diagnosis system

1. The CBS jobs can be reset via the diagnosis system on the following path: => Diagnosis => Function selection => Service functions => Maintenance => CBS reset
2. The individual CBS items are displayed in the BMW diagnosis system with service counter and availability.
3. The service counter is increased by 1 during the reset. All service counters are set to "1" on new vehicles.
4. Availability is set to 100 % during the reset. It is basically a display quantity indicating the wear level of the job. The greater the availability, the more distant is the next service appointment. 0 % means that the service item must be carried out.

61 00 ... Notes on handling wiring harnesses and cables

In general

To avoid damage, observe the following instructions

1. Avoid compressive and tensile loads
2. Make sure cables are laid without kinks or abrasions
3. Ensure non-contacting routing at sharp-edged body parts; use muckets if necessary
4. Secure additionally laid cables/leads with cable ties

In addition

Shielded cables (coaxial cables)

1. This may lead to indifferences in noise radiation and interference immunity at contact points in the shield
2. To satisfy the requirements of the type approval, it is essential to replace shielded cables completely

Fibre-optic cables

Note. Fibre-optic cables are coloured differently as follows

1. Green = MOST (M edia O riented S ystems T ransport) fibreoptic cables
2. Yellow = ISIS (I ntegrated S ervice I nformation S erver) fibreoptic cables
3. Orange=repair fibre-optic cables

Treating cables and fibre-optic cables

FlexRay

It is possible to repair the FlexRay. In the event of damage, the cables can be joined with conventional butt connectors.

Note. The cable is a twisted cable. If possible, maintain twisted cable after repair.

86 10 ... Positioning of multitrailer hood for maintenance and repair work

For maintenance and repair work, raise the hood using a lifting platform. Twin-column lifting platforms, body lifting platforms and twin-stamp underfloor platforms are suitable. The seating plates and areas of the lifting platform must be adjustable according to the dimensions of (Scheme 23).

Scheme 23

The lifting platform must conform to the relevant legal provisions of the accident prevention regulations and be serviced as specified. Comply with the lifting platform operating instructions, in particular the safety instructions and the carrying capacity.

Make sure you adhere to the BMW-recommended work area of 5 x 7 m and to an escape route of 0.6 m between two lifting platforms.

Please comply with the following instructions before raising the hood

1. Raise only when it is unloaded
2. Ensure sufficient clearance between the seating plates/seating areas and the GFP edge of the hood
3. The hood must always be positioned in the middle of the lifting platform.
