UCH
Vdiag No.: 0F
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.
*Powerlatch: Time required for injection computer supply after + 12V after ignition cut-off to the ignition switch. 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.

Check the battery voltage with the starter motor activated and the + starter supply.
Check the condition of the starter exciter terminal. Repair if necessary.
Check for +12V at the starter excitation terminal, when the starter is activated.
Repair if necessary (ignition switch supply, correct operation of the ignition switch and ignition switch/starter
connection).
If the fault is still not resolved, check that the starter motor is operating correctly. Replace the starter motor if
necessary (see MR 374, Mechanical, 16A, Starting - Charging, Starter: Removal - Refitting).

Check the battery voltage when the starter is turning and check the earth straps connecting the engine and
transmission assembly to the vehicle chassis.
Check that the starter motor has not seized or locked.
If the fault is still present, replace the starter motor (see MR 374, Mechanical, 16A, Starting - Charging, Starter:
