Information
Depending on the country, there are more or less strict laws or standards regarding the vehicle speed up to which the TV picture may be shown for the driver.
This speed threshold is coded as a fixed entry in PCM. The threshold is set to the lowest value (0 km/h + handbrake) ex-works (PCM supplier) for safety with regard to spare parts, etc.
An electronic code (18-digit code number) is needed to change this threshold value. It can be entered in PCM, Freely-selectable codes using the PIWIS tester.
During production in Leipzig, a specific code is worked out for each of the speed levels 0 km/h + handbrake, 0 km/h, 5 km/h and 9 km/h and this is stored in IPAS.
The required threshold is then coded in the vehicle (PCM) for the relevant target country. A combination of C No. (country code) and dealer/importer code is used for selecting the country at the end of production.
If the destination country for vehicles is changed, or if the PCM is replaced following repairs, for example, the threshold must be set to the value defined in the destination country (in Tuner Parameters ).
