DTC Description Possible Causes Action Battery voltage at electric
steering column lock control
module too low
Electric steering column lock
control module, instrument
cluster, central junction box
fault with the road wheel against a curb. If the
column lock is failing to disengage, the customer
may be able to rectify this by rotating the
steering wheel while pressing the engine start
button
If fault persists, complete a CAN network
integrity test using the manufacturers approved
diagnostic system. Alternatively, refer to the
electrical circuit diagrams and check CAN circuits
between the central junction box, the instrument
cluster and the electronic steering column lock.
Refer to the electrical circuit diagrams and check
the central junction box, the instrument cluster
and the electronic steering column lock power
and ground supply circuits for short circuit to
ground, short circuit to power, open circuit, high
resistance. Repair circuit(s) as required. Clear
DTC, perform an on demand self-test and retest
If fault persists, check that the vehicle battery
supply voltage is between 9-16 volts. Rectify as
required B100D-96

supply voltage is between 9-16 volts. Rectify as
required
Ensure the column lock bolt movement is not
obstructed or restricted (the parked position of
the road wheels may be exerting a turning force
through the steering column, preventing the lock
from releasing. The steering wheel may need to
be held against the force to allow the column
lock to release). Clear DTC, repeatedly lock and
unlock car using the key fob and retest
If fault persists, complete a CAN network
integrity test using the manufacturers approved
diagnostic system. Alternatively, refer to the
electrical circuit diagrams and check CAN circuits
between the central junction box, the instrument
cluster and the electronic steering column lock.
Refer to the electrical circuit diagrams and check
the central junction box, the instrument cluster
and the electronic steering column lock power
and ground supply circuits for short circuit to
ground, short circuit to power, open circuit, high
