(2) Precautions when connecting or disconnecting connectors.
(a) Before you disconnect any connectors related to the electric power steering system, turn the ignition to IG ON and set the steering to the straight-ahead position. Disconnect the connector after turning the ignition to IG OFF.
(b) Before you connect any connectors related to the electric power steering system, confirm that the ignition is turned to IG OFF, connect the connector and turn the ignition to IG ON while the steering is in the straight-ahead position.

CAUTION:
Do not turn the ignition to IG ON if the steering is not in the straight-ahead position.
