NOTESNo faults should be present or stored.
Only apply these checks if the status remains NO when a button on a key is pressed.
Special note:
This status enables you to check that the UCH is receiving the radio frequency signals
transmitted by a key that may or may not belong to the vehicle.
SPECIFICATIONSYES
NO
Does the status change to “YES” after one of the other buttons on the key is pressed?
YES
Replace the key.
NOCheck the operation of this status with another key for the New Twingo, Modus or Clio
III.
If the status changes to YES, check the condition of the first key's battery.
If the fault is still present, replace the key and allocate the key using command SC015
Key allocation.
If the status remains NO, consult the interpretation of DF054 Computer.
AFTER REPAIRRepeat the conformity check from the start.
Carry out fault finding on the system.

SPECIFICATIONSPRESSED
RELEASED
Check the presence and condition of fuse F5 (15 A) in the passenger compartment fuse and relay box
(component code 1016).
Replace the fuse if necessary.
Check the condition and connection of the brake pedal switch 4-track connector (component code 160).
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
On component 160, with the brake pedal depressed, check the continuity between connections AP10 and 5A
and the insulation of connections AP10 and 65A.
On component 160, with the brake pedal released, check the continuity between connections AP10 and 65A
and the insulation between connections AP10 and 5A.
Replace the switch if faulty. (See MR 411 mechanical systems 37A, Mechanical component controls, Brake
light switch: Removal - Refitting).
Check the condition and connection of connector PE1 of the UCH (component code 645) (tabs bent, oxidised,
broken).
Check for + 12 V (+ battery feed) on connection AP10 of the brake switch connector (component code 160).
If it is not correct, check the insulation, continuity and the absence of interference resistance of connection
AP10 between components 160 and 1016.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRRepeat the conformity check from the start.
Carry out fault finding on the system.

Check the condition of the key battery and of the button contacts.
Replace the battery if necessary.
Try the vehicle's second key.
If the status changes to Active, replace the first key and allocate the keys using command SC015 Key allocation.
If the fault is still present, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

ALTERNATOR CHARGE SIGNAL
NOTESNo faults should be present or stored.
Note:
In the event of a malfunction, the value will by 99.6% (engine running).
Depending on the battery charge status, the operating phase and the battery temperature, the UCH determines
what the voltage across the battery terminals should be.
When the battery charge drops, and PR076 Battery voltage after rest decreases, the UCH can temporarily
increase the PR075 Alternator setpoint voltage by 1 V and for a period of 15 minutes after switching on + after
ignition feed.
Before and during starting, PR075 Alternator setpoint voltage is fixed at 10.7 V.
A maximum of 30 seconds after the engine has started, the UCH sets PR075 Alternator setpoint voltage to the
optimum value calculated.
The injection computer can also control the alternator (component code 103) regulation voltage.
The injection computer sends the maximum authorised power delivered by the engine, to the UCH via the
multiplex network.
If the power available by the engine is less than the power consumed by the alternator (component code 103),
the UCH reduces PR075 Alternator setpoint voltage.
0 % < PR073 < 100 %
In the event of a fault, carry out a complete check on the battery and the charging circuit (see Technical Note
16A, Starting-Charging).
If the fault is still present, contact Techline.
AFTER REPAIRRepeat the conformity check from the start.
