Keyless Entry: Service and Repair
REPROGRAMMING REMOTE TRANSMITTERS (Scan Tool Function 07)Central Locking
The two central locking system variations can be coded according to the possible function/equipment variations.
Central locking system variations:
- Central locking with anti-theft warning system
- Central locking with radio-frequency operated remote control and anti-theft warning system
NOTES:
- Basic functions of the central locking system variations are listed in the standard coding table. See below.
- If a customer requests a special, individual coding of the central locking system, use the questions see below to determine the correct system coding.
Standard Coding Table
NOTE: Always check whether the ultrasonic interior monitor has On Board Diagnostic (OBD) capability (refer to footnote).
1) The vehicle has ultrasonic interior monitoring with OBD capability (i.e. with address word 45), there is a signal from the control module for ultra-sound sensors -J347-.
Coding Questions For Individual Central Locking Functions
NOTES:
- First determine which central locking version this vehicle has (e.g. what central locking and anti-theft warning system).
- Make a copy of the applicable table for the current vehicle coding.
- Answer all questions in the table with a "yes" or "no." In the last column, enter your copy of the number of answers.
- If in doubt, ask the customer what central locking functions are desired.
- Total all the results from top to bottom. The total gives the valid control module coding. Add the figures up again as a check.
- Examples of coding calculations, see below.
Table I: Vehicles With Central Locking And Anti-theft Warning System
1) Only one of questions 4 and 5 can be answered with "yes," but both can be answered with "no."
Table II: Vehicles With Central Locking And Anti-theft Warning System
1) Only one of questions 4 and 5 can be answered with "yes" , but both can be answered with "no".
Example Of A Special Central Locking Coding
This is a case of an Audi A8 with central locking and anti-theft warning system. A safety central locking system is desired. The USA door locking logic must be activated and setting of the anti-theft warning system will be confirmed by triggering the 4-way flashers. The ultrasonic interior monitoring has no On Board Diagnostic capability.
1) Only one of questions 4 and 5 can be answered with "yes," but both can be answered with "no."
