BMW 7 Series: Initializing Rain/Light (Solar) Sensor

NOTE: Initialization is necessary:

• after replacing windscreen
• after replacing rain/light (solar) sensor
• after replacing optics on rain/light (solar) sensor
• after installing a used rain/light (solar) sensor

NOTE:

• Connect BMW diagnosis system
• Initializing rain/light (solar) sensor

NOTES ON ESD PROTECTION (ELECTRO STATIC DISCHARGE)

Notes

NOTE: Electrical components which are particularly sensitive to electrostatic discharge (electronic control units, sensors, etc.) are marked with the ESD warning symbol.

E - Electro
S - Static
D - Discharge

Statically charged persons can discharge themselves when they touch electrical components.

NOTE: Humans can only detect a discharge starting from a level of approx. 3000 V.

The danger threshold for electrical components already starts from a level of approx. 100 V.

Example: Mechatronic control unit.

Fig. 285: Precaution For Pins And Multi-Pin Connectors Directly

IMPORTANT: Do not touch pins and multi-pin connectors directly!

Touch electrical components by their housings only.

IMPORTANT: To avoid damaging or destroying electrical components as a result of electrostatic discharge, it is absolutely essential to observe the following instructions:

• When replacing electrical components, leave the replacement components in their original packaging until immediately before they are to be installed
• If necessary, always return a removed component in its original packaging (always pack the component away immediately)
• Read and comply with user information on using the associated special tool 12 7 060

Personal protective equipment:

Electrically conducting clothing (high wool content, antistatic shoes required).

These can primarily be identified by the logo on the side.

PROGRAM / ENCODE THE CONTROL UNIT (E)

NOTE: In order to avoid incorrect programming procedures and fault messages, it is essential to always use the most current version when working with the ISTA/P programming system.

NOTE: Battery voltage must not drop below 13.0 V during programming. Connect battery charger prior to programming Use only BMW-recommended battery chargers* *Sourcing reference Workshop Equipment Catalogue.

programming routine via ISTA/P:

• Connect the battery charger to the vehicle.
• Connect the programming system with the vehicle.
• Determine the action plan and, if necessary, add complete car coding to the action plan.
• Accept action plan with the control units to be programmed/encoded and enabled, if necessary or work through.
• Observe the reworking list!
• Connect the workshop system to the vehicle.
• Perform brief test and delete fault memory.
