Control units
Variants
Depending on the vehicle's target market and the vehicle equipment specification, a variety of demands are
placed on the entry and start authorisation system. The resulting type diversity is covered only by different
variants of the entry and start authorisation switch E415. The switch variant is determined by the following
vehicle characteristics:
● with or without Advanced Key
● with automatic or manual gearbox (due to ignition key withdrawal lock)
● radio frequency of the ignition key (315 MHz, 433 MHz or 868 MHz)
The entry and start authorisation control unit J518 as well as the aerial reader unit for entry authorisation for
keyless entry system J723 are available in one variant only.
