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.
