If the customer has not reported a non start
issue, clear the DTC and check vehicle starts
correctly. If a non start issue has been reported
run the manufacturers approved diagnostic
system Start Authorisation Application and
follow the actions required for this DTC. Carry
out any pinpoint tests associated with this DTC
using the manufacturer approved diagnostic
system. Check CAN communication between
Electronic Steering Column Lock and instrument
cluster (check transmission out speed, vehicle
speed, engine speed, gear position and
powermode signals to Electronic Steering
Column Lock). Refer to the electrical circuit
diagrams and check Electronic Steering Column
