PR001
BATTERY VOLTAGE
NOTESCheck that the battery terminals are correctly tightened.
Check the consistency between the battery voltage measurement from the multimeter and the value of PR004
Battery voltage.
Engine stopped: 11 V < X < 13.5 V.
Engine running: 10.5 V < X < 16 V.
If the voltage values are not consistent (greater than 0.3 V difference between the 2 values), check the connection
between the + battery feed and the Protection and Switching Unit.
If the values are consistent, run fault finding on the battery and charging circuit (see Technical Note 6014A,
Checking the charging circuit, 16A, Starting - Charging).
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.

ALP45 Impossible to stop engine
NOTESOnly check this customer complaint after performing a complete check with the
diagnostic tool.
Check whether the engine switches off if the Start button is pressed twice.
If it does, make sure the card is not considered absent by the UCH, particularly by checking for messages on the
instrument panel.
Check that the button presses are detected correctly by the UCH using status ET070 Start button.
If not, see the procedure for dealing with this status.
Check that status ET110 UCH request to injection or UPC is STOP when the button is pressed.
If there is a fault, see the procedure for this status.
Check the consistency of parameter PR008 Vehicle speed with the vehicle stationary.
If not, run fault finding on the ABS.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a complete check with the diagnostic tool.

ALP46 Steering lock fails
NOTESCheck for any faults on the steering lock.
Check the battery voltage. It should be between 9 V and 16 V.
Check the validity of parameter PR008 "Vehicle speed".
Check for any faults in the Airbag computer (impact detected) and ABS/ESP
computers.
Reminder: In hands-free mode, the steering column lock is locked as soon as the
ignition is switched off.
With the card in the reader, the steering column lock is locked after the ignition is
switched off as soon as the card is removed from the reader.
The conditions for a drop in + after ignition feed without the steering column locking are:
–the card is present in the card reader,
–over 20 minutes passing with the card in the card reader after the engine has stopped,
–the vehicle speed is not zero,
–power being requested by the steering column lock too frequently.
With regard to vehicles fitted with UCH computer Vdiag 4F or above:
–the Renault card is removed from the card reader when the vehicle is in forced + after ignition feed,
–3 mins have elapsed following a starting failure due to an engaged gear,
–the Renault card is removed from the card reader following a starting failure due to an engaged gear,
–a front door is open following a starting failure due to an engaged gear and the card is not in the reader.
Check that these conditions are not present.
Check the consistency of statuses ET072 Steering column lock and ET073 Steering column lock signal.
In the event of a fault, see the procedure for these statuses in the UCH section.
Check that the steering column lock belongs to the vehicle using status ET248 Steering column lock immobiliser
code.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a complete check with the diagnostic tool.
