it for 50,000 working cycles at a temperature of between -30 °C to + 60 °C.
Batteries from competing brands can be easily found on the market, but the Bosch warranty is not valid unless only PANASONIC

batteries are used.
Replacing the battery
Battery replacement should not take longer than 3 minutes. When fitting the new battery pay attention to battery polarity.
If you fail to comply with the foregoing instructions the ROLLING CODE necessary to transmit the signal from the key to the

control unit will be deleted.
The ROLLING CODE can be reset by following the key synchronisation procedure.
Key synchronisation procedure
- introduce the key into the switch
- turn it to start
- press the remote control button
This procedure makes it possible to reset the ROLLING CODE

Electronic central control unit (ECU)

The central control unit is located underneath the central dashboard. It controls both centralised closing/opening of the doors

and activation/de-activation of the anti-theft protection by means of the signal supplied to it by the remote-control key, with

the consequent switching on of the remote-control switches located inside the actual control unit.
If one of the remote-control switches should be blocked (working contact blocked) during operation, causing continuous

activation of the door-locking motor(s), the control unit will switch on remote-control switches that create bridges on the

remote-control switch in question, in order to avoid serious damage to the motor(s) concerned. Once normal operation of the

faulty remote-control switch is reinstated, then these remote-control switches will switch off.
The central unit is connected to the cable in the cab/bonnet by means of one 12-pin connector and one 28-pin connector. Each

central unit has a pin code, which is programmed at the end of the line test. This pin code will consist of 5 digits, each of which

will be a binary-coded decimal number from 0 to 9.
In addition, the ECU detects faults in the system, signalling the by causing the anti-theft signalling LED at the centre of the ceiling

light to flash. It is possible to identify two types of failure: minor and major. In the first case, with the +15 power supply on, the

LED will remain on without flashing, while in the second case, again with the +15 power supply on, the LED will flash. Major failures

are those concerning the ECU, and are caused by:
- an error in the ROM/RAM check sum
- an error in the EEPROM check sum
- remote-control switch with working contact blocked.
