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.

–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.
