Vdiag No.: 09
Starting
The UCH controls the command and supply part of the start-up function and the starting and charging process is
controlled by the UCH. For this function to operate normally, the protection function must have been successfully
completed.
IMPORTANT:
When the vehicle battery has a low charge, the drop in voltage caused by operating the starter could reactivate
the immobiliser. If the voltage is too low, the engine cannot be started, even by pushing the vehicle.
Note:
If several, i.e. three or four, attempts have been made using a key not allocated to the vehicle, the injection
computer locks. Insert a key allocated to the vehicle for 20 seconds in + after ignition feed, then switch off
the ignition and wait for the end of power-latch (20 minutes) to allow the injection computer to unlock.
* Powerlatch: Injection computer power supply duration after + 12V after ignition cut-off to the ignition switch.
