Good afternoon all,

My door contacts are not working anmore (all four doors) of my E70 from 2010, and I already tried replacing the FRM and also replacing the complete door locks. I also measured the wiring, which is also ok.

I discovered on the internet that this error can be caused by a coding error. There is a service bulletin of BMW about this. Please see below.

I have ISTA-P versin 3.66, but I don't have the conversion option mentioned in the service bulletin. How can I obtain this conversion?

Thanks in advance and best regards Hendrik

Vehicles produced from August 31, 2009 to March 31, 2012

SITUATION

One or more of the following situations can occur:

1. While the vehicle is in motion, a CC (Check Control) message in the KOMBI (instrument cluster) indicates that the doors are open, even

though they are closed. In addition, a warning gong sometimes sounds, along with the interior lights turning on and off. This can affect all the doors.

2. The battery is discharged due to the FRM3 (footwell module) constantly waking the vehicle.

These situations can occur intermittently. The following fault code memory entries may also be present in the FRM:

- 0x9CBC - short-circuit or break in circuit in front door contacts, and/or
- 0x9CBD - short-circuit or break in circuit in rear door contacts

CAUSE

A coding error in the FRM3 is causing incorrect door contact detection.

[NEW] PROCEDURE

1. Perform a vehicle test using ISTA/D (Integrated Service Technical Application, Diagnosis) and complete relevant test plans for any FRM fault

codes that are stored.

Note:

When the ISTA system message displays: Battery voltage only "XX.XX" V. Please connect charger. Please note the displayed battery voltage reading in the repair order comments section.

2. Perform the conversion "Activate threshold change door contact" with ISTA/P 2.46.0 or higher. The HO word "SWTK" will be added to the

VO.

Note:
After this conversion is added to the measures plan, finish the programming/coding procedure by accepting the measures plan and following the instructions as indicated in ISTA/P.
